Marktech Optoelectronics Releases New Green and Red Dot LEDs – Just in Time for the Holidays

Marktech’s Introduces Standard Green Dot LEDs and Expands Red Dot LED Line-up

Marktech Optoelectronics, Inc. (www.marktechopto.com)(Marktech), a privately-held leading designer and manufacturer of standard and custom optoelectronics, including UV, visible, near-infrared (NIR), and short-wavelength infrared (SWIR) emitters, detectors, InP epi wafers, and other compound semiconductors, today announced the release of their enhanced sharpness 25 and 50 micron green dot point source LEDs (MTSP-1358 and MTSP-1360) for reflex sights, riflescopes, sports optics, camera viewfinders, and other aiming applications. In addition, Marktech expanded their offering of red dot LEDs with additional micron sizes and package types.

Our green dot LEDs utilize a “true green” 520nm wavelength, which appears brighter to the human eye compared to a 650nm red point source with equivalent power output. Green dots appear “brighter” because the rod receptors in the human eye have the more response to 520nm green light than 650 red light. However, red dots are still desirable in many applications. For instance, if the background, foliage, or target is a similar shade of green, then a red dot might be a better option.

Standard red dot LEDs micron sizes include 25 µm, 50 µm, 80µm, 100 µm, and 150 µm. Red dot LEDs with micron sizes of 10µm, 13µm, 30µm, 40µm, and 60µm available on a custom basis. Our standard red dot LEDs are available in two package types: a 2.1×2.1 SMD Flat Lens and a 1.6×1.5 SMD Flat Lens. Several additional package type options are available such as chip on board (COB) and flex circuit. Marktech can also custom design package for OEM needs.

Marktech’s 2.1mm x 2.1mm package for dot or point source LEDs.

Marktech’s red dot-circle-cross reticle LED with individually addressable elements.

Marktech can assemble the red dot or reticle die into various standard and custom packages as well as chip-on-board (COB), rigid PCB, and flexible circuit assemblies. We have also incorporated our avalanche photodiode (APD) detectors in conjunction with red dot and display reticles for riflescopes, binoculars, LIDAR speed guns, and rangefinders with laser distance, speed, or range measurement capabilities.

Red Dot LED Product Applications
The typical function of red dot and reticle LEDs is aiming or targeting. The red dot appears within the riflescope or reflex sight. The reflected image of the red dot LED on the optical lens provides a virtual spot on the target. Unlike aiming lasers, a visible laser spot does not appear on the target, so the prey or target cannot see the spot. In addition, specialized coatings are used on the optics to enhance reflections or the red light wavelengths from the LED, which reduces the appearance of the red dot to prey, enemy combatants, or other targets.

While the recognized leader of premium red dot LEDs to the optical scopes industry, Marktech red dot and reticle LEDs find additional applications outside riflescopes and gun sights. Laser rangefinders and LIDAR speed guns often utilize a red dot aiming sight to target an object for measurement. Telescopes have a narrow field of view and require finderscopes or red dot finders to locate specific stars or constellations. An increasingly popular application of red dot LEDs is on cameras. A red dot viewfinder on a camera is helpful in the photography of fast-moving objects.
Red dot, reticle, and alphanumeric LEDs benefit a wide range of applications, including:

  • Riflescopes
  • Reflex Sights and Red Dot Sights
  • Illuminated Reticle Scopes
  • LIDAR Speed Guns
  • Optical pyrometers
  • Telescope Finderscopes or Red Dot Finders
  • Night Vision (NV) Devices
  • Rangefinders & Range-finding Binoculars
  • Camera Red Dot Viewfinders
  • Stage Lights and Spot Lights
  • Ocular Displays in Microscopes and Medical Optics
  • Displays in Smart Glasses, Goggles, and AR/VR Devices
  • Head-mounted display in scuba masks and helmets
  • Optical encoders
  • Edge sensors
  • Proprietary OEM Optical Assemblies.

Packaging Options

Marktech’s dot and reticle LEDs are available in various package types depending on the requirements of your application. For instance, our 25µm and 50µm red dot LEDs are available in both a 2.1mm x 2.1mm SMD packge and a more compact 1.6mm x 1.5mm SMD package. For applications requiring a larger package such multiple dot LEDs, reticle LEDs and microdisplay LEDs, we have 3mm x 4mm frameless SMD, COB, flex circuit, and custom designed packaging options.

Point Source LEDs

Our small 10 µm diameter red dot LEDs and visible or NIR point source LEDs can replace lasers in specific applications. They are also used as emitters in optical encoders, position sensors, edge sensors, light barriers, and other sensing applications. For sensing applications requiring higher power visible or infrared (IR) emission, Marktech has a series of point source LED emitters from the 620nm to 650nm in the visible band and from 750nm to 980nm in NIR band.

“We are proud to offer our customers what we believe are the best dot or point source LEDs in the market. Our innovative manufacturing processes and rigorous inspection ensure that every green, red or NIR point source we produce meets the highest standards of clarity, brightness, and durability.

Buying Your Engineer or Scientist a New Photodiode for Christmas? 8 Questions to Ask When Selecting A Photodetector Manufacturer

Marktech’s innovative hybrid and silicon-InGaAs detectors.
Si-InGaAs photodiodes can enable broadband detection from 254nm to 2600nm

1. How extensive is the photodiode manufacturer’s product offering? Do their photodiodes have the wavelength sensitivity, speed, active area, and other performance parameters to meet your photo- detection requirements?

The supplier should have a broad enough product line to meet your current and future needs.

They should have photodiodes in their line-up meeting your application’s wavelength sensitivity, speed, dark current, and size needs. For example, Marktech produces both silicon and indium gallium arsenide (InGaAs) photodiodes, which provide a wavelength sensitivity range from 250nm to 2600nm – or, over the ultraviolet (UVB), visible, near infrared (NIR) and short wave infrared (SWIR) bands. Marktech has an extensive line-up of photodiode detectors with these wavelengths with a range of active areas and package types. However, suppose the supplier only has one or few types of photodiodes. In that case, photodetectors may not be their main focus. As a result, they will not be able to provide as many choices, assistance in selecting the suitable detector, and guidance in developing detector specifications.

Marktech has 500+ standard or catalog detectors, LED products, and over 3000 customized products. Most catalog products are available immediately through our distributors, Digi-Key Electronics and Mouser Electronics.

In 2021, Marktech products became available in Japan through our latest partner, Rikei Corporation. Established 65 years ago in Tokyo, Rikei Corporation is a trusted trading partner and value-added solutions provider serving many electronic original equipment manufacturers (OEMs) and communications companies. Rikei excels in system integration and component distribution, leveraging superior procurement skills, deep domain knowledge, and expertise in systems technology and electronics for high-quality solutions throughout the project lifecycle.

Marktech also has sales engineering representatives in Canada (ARL Group), Israel (Militram), and France & Germany (Syscom-Prorep). Our extensive offering and ability to tailor products to specific OEM design specifications have long set Marktech apart from other optoelectronic manufacturers. For example, Marktech’s photodiode detectors have various wavelength sensitivity ranges, active area sizes, and package types including TO can, SMD, PLCC, through-hole, and hermetic SMD packaging.

2. Are they familiar with specifying photodiodes for your industry application? Can the manufacturer modify or customize their photodiodes to suit your needs?

Custom 64 element Si PDA for ice particle measurements on aircraft wingtip.

The supplier should be familiar with your application or ideally developed or customized photodetectors for similar use cases. Every application can have unique details necessitating intricate modifications to detector specifications to enable viable detection levels. Off-the-shelf or catalog photodiodes can be sufficient for less demanding applications. However, we have found in many cases that customization of a photodiode in terms of wavelength sensitivity, active area size, package type, and hermetic properties can increase the overall performance and reduce the total cost of your design. The custom component cost might be slightly higher, but reducing part count and simplifying circuit designs can result in a total cost benefit. In addition, Marktech can further customize photodetector designs by adding amplifiers, thermionic coolers, and LED emitter in the same package. Marktech can also apply anti-reflective coatings and filter coatings to windows or lids. Marktech has partnered with many OEMs to develop specialized InGaAs and silicon photodiode detectors for aerospace, analytical instrument, automotive, automation & industrial sensing, medical, and wearable applications. Our products can be found on satellites, top-tier automobiles, non-invasive medical diagnostic devices, position sensors, spectrometers, refractometers, laser alignment systems, and colorimeters.

3. Does the supplier produce LED emitters with your application’s wavelength, power output, and package type?

Position sensing, spectrometry, refractometry, LiDAR, security, and other industrial applications often use photodetectors in conjunction with an LED emitter or light source. Therefore, the manufacturer should have LED emitters with the wavelength and power ranges to complement the photodetector selected. Marktech has an extensive line of LED emitters to provide the proper light source for InGaAs and silicon photodiode detectors selected. Marktech’s testing laboratories can evaluate both emitters and detectors. In addition, our labs can customize or sort LEDs to tighter or lower variations in peak wavelength (±1nm). Our optoelectronics engineers and LED experts can further customize LEDs with packaging and assembly options such as flex circuits, COB, and PCB.

4. How long has the photodiode manufacturer been in business under the same ownership? Are they increasing in size, facilities, and capabilities?

The photodiode manufacturer should be a stable business. If the manufacturer has changed hands through acquisitions or bankruptcies, closed factories, or cut many detector product offerings, then the supplier may not be the best supplier. Instead, look for an established supplier with stability and expanding product offerings, capabilities, manufacturing plants and testing laboratories. Marktech was founded in 1985 by Mark Campito, a Navy veteran, who is still the CEO. Marktech has continuously focused on testing and invested significantly in creating world-class optoelectronic testing laboratories capable of analyzing photodiode detectors and LEDs. Marktech’s philosophy is that optoelectronics testing is crucial in maintaining product quality and consistency. In 2021-22, Marktech upgraded our detector and LED testing facilities in Latham, NY. Marktech also installed extensive burn-in test capabilities for component and assembly evaluations. In 2014, Marktech built and opened a new state-of-art silicon photodiode manufacturing plant in Simi Valley, California. Marktech Optoelectronics has continuously operated in New York State since 1985.

5. Does the supplier have a history of innovation, quality, and reliability? How often are new products added to their line-up?

Cutting-edge optoelectronic design require a supplier with innovative product and a willingness to customize and try new approaches, and expand the capabilities of their photodiode when required by a customer’s application. The frequent additions of new products to a photodiode manufacturer’s catalog indicates growth and innovation. Marktech is constantly adding new and innovative product to their portfolio of photodetectors and LED emitters. In addition, Marktech’s photodiode detectors are recognized and sought after for their integrity and reliability. In 2023, Marktech’s ATLAS Hermetic SMD Packaged InGaAs Photodiodes won the Best of Sensor award in the Aerospace/Space category at the Sensors Converge conference and exhibition. The award demonstrates Marktech’s ability to develop and manufacture high performance photonics products. Marktech’s award winning, compact hermetic SMD ATLAS packaged InGaAs photodiode (right) compared to a bulky TO can packaged detector (left).

6. Is the photodiode supplier an integrated optoelectronics manufacturer?

Ideally, the photodiode supplier you select will be “integrated” or manufacture the photodiodes device at the wafer level, dice the wafers into photodiode chips, package the chips, and when required assemble onto printed circuit boards (PCB, COB, flex circuits). Manufacturing integration provides more control of the quality and consistency because a single company oversees every step of the photodiode manufacturing process. There is no finger-pointing between suppliers, and any quality issues are quickly identified and resolved. New photodiode detectors are rapidly developed and delivered as well. Marktech is an integrated InGaAs photodiodes manufacturer. Our InGaAs photodiodes are fabricated on our Custom Designed MOCVD chambers in Japan. The InGaAs detector die are packaged, assembled, and tested in the same facility. Our Japanese factory has extensive optoelectronic engineering and photodiode design expertise.

Our InGaAs photodiode detector factory in Japan

7. Can the manufacturer fully test the characteristics of photodiodes and LEDs? What type of testing facilities does the manufacturer have for evaluating photodiodes and LED emitters?

The ability to test is essential in assuring quality, troubleshooting application problems, and simulating field conditions. In some cases, testing can show how variations in the application or use of a photodiode causes detection issues, which can be resolved through packaging, end-product design changes, or photodiode chip specification adjustments. Marktech has extensive expertise and laboratories for optoelectronic testing of both detectors and LED emitters.

8. Will the manufacturer be able to deliver in time to meet your design project schedule? Does the supplier have catalog or standard photodiodes available through major distributors? Where are their photodiode manufacturing facilities located?

Photodiodes should be manufactured in a country without supply chain issues arising from COIVD shutdowns, political upheavals, sanctions, or transportation problems. Ideally, your photodiode supplier should be located near your factory or within the same country. If the manufacturer has a catalog or standard offering of photodiodes, then these products could be delivered rapidly. In addition, while the specific photodiode might have to be customized for your application, a standard photodiode might help move the development process forward and collect data to finalize the photodiode specification.

Marktech has manufacturing facilities in Simi Valley, California and in Japan. We have extensive optoelectronic engineering and testing laboratories in Latham, New York and in Japan. Marktech has one the shortest delivery lead times in the photodetector industry for standard and custom photodiodes. Marktech’s standard photodiodes are available through Digi-Key Electronics and Mouser Electronics, so there is still time to order a new photodiode optical sensor for your special person.

Marktech Optoelectronics Announces the Launch of Innovative Quadrant Silicon Photodiode – MT03-072

Marktech’s New 50mm Active Area Silicon Quad PD

[Latham, NY, November 28, 2023] – Marktech Optoelectronics, a renowned leader in optoelectronic components, is excited to announce the release of its latest innovation, the Quadrant Silicon Photodiode, part number MT03-072. This state-of-the-art photodiode meets the advanced needs of applications such as beam centering, beam nulling, position centering, beam alignment, optical tweezers, atomic force microscopes (AFMs), fine sun sensors (FSSs), and free space optical receivers.

Marktech's new New 50mm2 Active Area Si Quadrant Photodiode MT03-072
New 50mm2 Active Area Si Quadrant Photodiode MT03-072

The MT03-072 stands out in the market with its unique packaging in a hermetic TO-8 metal can. This robust packaging is expertly engineered to protect the photodiode and maintain optimal performance even in the most challenging environments. It effectively prevents the ingress of oxygen, moisture, water vapor, and other corrosive gases known to degrade semiconductor materials. These attributes make the MT03-072 exceptionally reliable and durable compared to products in standard plastic SMD or non-airtight packages.

One of the remarkable features of the MT03-072 is its non-outgassing nature in vacuum, low-pressure process chambers, or space environments due to its all-metal package containing no plastic or volatile organic compounds. This characteristic is crucial for high-precision applications where outgassing can significantly affect performance and results or damage the detector.

The MT03-072 quadrant photodiode or photodetector are made using Marktech’s proprietary Series 8 SiPD process offering a responsivity range from 350nm to 1100nm, with a peak sensitivity around 940nm to 980nm. This broad range ensures that it caters to a wide spectrum of applications, delivering high detection efficiency coupled with low noise.

For example, near infrared (NIR) laser beams with wavelengths of 800 to 980nm, 940nm, and 1064nm are commonly utilized for optical tweezing biological materials like cells, bacteria, or spores. NIR light provide a good balance between minimizing photodamage, low interference with fluorescence imaging excitation, and producing effective trapping forces. Atomic force microscopes are used to manipulate cells as well as measure surfaces at the atomic and nanoscale. These instruments utilize NIR lasers and quadrant photodiodes for precise position measurement of their cantilever or probe deflections. Marktech quad PDs are ideal for optical tweezer and atomic force microscope (AFM) applications.

Quadrant photodiodes are also used as optical receivers in free-space optical communications systems. A laser beam transmits a signal to a quadrant receiver using visible, NIR, or SWIR wavelengths. Water vapor, carbon dioxide, and other gases absorb light at specific wavelength ranges. Optical transmission bands occur between these regions of high absorption. Typical NIR laser wavelengths for free space communications include 808nm and 1064nm (Nd: YAG lasers), well within the MT03-072 photodiode specifications.

“Marktech is committed to pushing the boundaries of optoelectronic technology, and the launch of the MT03-072 is a testament to our dedication to innovation and quality,” said Vincent Forte, Chief Technology Officer (CTO) at Marktech Optoelectronics. “We are proud to offer a new product that not only meets but exceeds our customers’ expectations in terms of performance, reliability, and environmental resistance.”

Marktech Optoelectronics Awarded Veteran-Owned Small Business Certification

Marktech Veteran Owned Small Business Certification

July 23, 2019 – Latham, NY, USA  Marktech Optoelectronics, Inc. (www.marktechopto.com)(Marktech), a privately-held designer and manufacturer of standard and custom optoelectronics components and assemblies, including UV, visible, near-infrared, and short-wave infrared emitters, detectors, InP epiwafers, and other materials, for aerospace, automotive, industrial automation, in-laboratory R&D, medical, robotics, sensors, wearables, telecommunications, and other applications, today announced the achievement of its veteran-owned small business certification (VOSB).

This Marktech VOSB certification, awarded by the United States Department of Veteran Affairs (VA) Office of Small and Disadvantaged Business Utilization, via its Center for Verification and Evaluation (CVE), follows the company’s successful completion of a nearly year-long stringent application process. Over the next three years, this certification affords Marktech new eligibility under the Veterans First Contracting Program for VA federal contracting opportunities and related set asides, and with subsequent potential for certification renewal.

Marktech is the only known U.S. optoelectronics manufacturer to currently have such a distinction.

Notes Marktech CEO, Mark Campito, “Speaking equally, as both a proud U.S. Navy veteran, who originally enlisted under the G.I. bill, and a proud 40-year veteran of the optoelectronics manufacturing industry, this certification brings with it a special sense of honor, as it combines both of those rewarding histories in a truly innovative way. Marktech looks forward to the prospect of new opportunities to grow our business with the federal government now afforded to us with this certification. At the same time, we remain grateful to the many OEMs who champion diversity initiatives within their supply chains, including for U.S. veteran-owned small businesses like ours.”

The VA’s Veterans First Verification Program affords verified firms which are owned and controlled by veterans and service-disabled veterans the opportunity to compete for VA set asides. During verification, the CVE verifies SDVOSBs/VOSBs according to the tenets found in Title 38 Code of Federal Regulations (CFR) Part 74 and 13 CFR Part 125 that address veteran eligibility, ownership, and control. In order to qualify for participation in the veterans First Contracting Program, eligible SDVOSBs/VOSBs must first be verified. Applicants are verified in four unique stages: intake, assessment, federal review and decision.

Marktech Announces Successful InP Epitaxial Crystal Technology Development for Ultra-High-Speed (5G) Large-Capacity Signal Processing Applications

InP epitaxial crystal

April 24, 2019 – Latham, NY, USA  Marktech Optoelectronics, Inc. (www.marktechopto.com)(Marktech), a privately-held, veteran-owned leading designer and manufacturer of standard and custom optoelectronics components and assemblies, including UV, visible, near-infrared, and short-wave infrared emitters, detectors, InP epiwafers and other materials, today announced its successful in-house development of InP epitaxial crystal mass production technologies for ultra-high-speed (5G) large-capacity signal processing applications.

The Marktech R&D efforts were carried out under the direction of Dr. Gako Araki, a 25-year expert in ultra-high-speed InP HBT and HEMT epitaxial crystal growth technologies. A member of the Marktech team since 2010, Dr. Araki’s experience further includes a progressive series of related R&D tenures at the New Energy and Industrial Technology Development Organization (NEDO) and NTT Advance Technology Corporation, both in Tokyo, Japan.

Research was carried out in two distinct phases. Phase One consisted of ultra-high-speed (5G) lnP epitaxial crystal growth technology development using small prototype MOCVD equipment (4inch.x4). Phase Two consisted of actual ultra-high-speed (5G) lnP epitaxial crystal manufacturing using large mass-production MOCVD equipment, known as GAKOUS (4inch.x10).  Given that true lnP-HBT epitaxial crystal performance testing requires electrical characteristic evaluations on larger HBT devices, Marktech instead focused R&D efforts on the development of new manufacturing equipment which could produce InP-HBT epitaxial crystals with the necessary uniform quality, size and quality for large-capacity ultra-high-speed (5G) signal processing applications. These goals were successfully achieved via a new crystal manufacturing method: carbon-doped InGaAs growth without hydrogen.

The Marktech evaluation of the small MOCVD prototype derived from this equipment showed favorable performance characteristics. Marktech then performed successful high-frequency HBT electrical characterizations on the prototype with equally favorable results. As a result, Marktech was able to conclude its successful development of new lnP HBT epitaxial crystal growth production equipment, known as MOCVD GAKOUS, whose capabilities offer the necessary prototype growth technology reproducibility and uniformity for manufacturing quality control in ultra-high-speed (5G) lnP epitaxial crystal growth applications.

As a final accompaniment to this R&D, Marktech developed a series of non-destructive electron mobility measurement systems. This included time-resolve photoluminescence testing with infrared wavelength area measurements, a technique which proved useful in the performance of lnGaAs channel layer quality checks, as well as HBT gain estimates by p-lnGaAs base layers during crystal growth and production. Using these techniques, it was determined that the Marktech small MOCVD prototype 4inchx4 exhibited satisfactory performance with new organic materials, independent source injection and a narrow gap placed between the injector and surface to avoid complex surface reactions. As a result, Marktech developed its new MOCVD GAKOUS equipment to produce lnP epitaxial crystal material which could offer the same performance and reliability as that of the prototype, yet with sufficient quality and uniformity for larger-scale commercial lnP HBT and HEMT crystal production volumes.

Of this research, Marktech CEO, Mark Campito, notes, “Marktech is proud of the R&D work of Dr. Araki in the area of InP epitaxial crystal mass production technologies for ultra-high-speed (5G) large-capacity signal processing. Our team’s commitment to proactive R&D efforts that address diverse or emerging market sector needs has been well-demonstrated over the years, whether that’s a 5G application, LiDAR, wearables, or others. We look forward to working in partnership with key 5G industry players to help them achieve their device performance goals.”
