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 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. Whether you need a standard or custom red dot LED or point souc, Marktech can deliver it with speed and efficiency.”
