SWIR and MWIR LEDs

Marktech is one of a few limited manufacturers that supply emitters in the extended NIR wavelength or SWIR (Short Wavelength Infrared). The SWIR spectrum spans from 1020nm to 3000nm wavelengths. In addition, we are now providing mid-wave infrared (MWIR) LEDs . The MWIR spectral range encompasses 3000nm to 5000nm (3µm to 5µm). Our standard product offering includes wavelengths from 1020nm to 4300nm and operating currents ranging from 20mA to 350mA for high-power applications.

Marktech’s series of SWIR and MWIR LEDs are available in a variety of package types such as ATLAS hermetic SMD, metal hermetic TO-cans, conventional surface mount device (SMD), plastic molded through-hole, chip scale packaging (CSP), chip-on-board (COB), starboards, linear boards, and custom packaging designed to meet specific OEM requirements. These short and mid-wave IR emitter devices achieve optimal performance for gas monitoring, moisture sensing, medical diagnostics, flame detection, chemical analysis, fiber optical communication, military, optical switching, and material sorting. The SWIR spectral range is also known as the Extended NIR or NIR II (NIR2).

Product Information

Discover the cutting-edge realm of short wave infrared (SWIR) technology with Marktech Optoelectronics’ innovative SWIR LEDs. These LEDs harness the power of short-wave infrared light, offering unparalleled performance and energy efficiency for many applications. Operating in wavelengths typically between 1000nm to 3000nm, SWIR LEDs penetrate materials more effectively than NIR LEDs, revealing characteristics invisible to the human eye and standard NIR cameras. Ideal for industrial inspection, night vision, spectroscopy, and medical imaging applications, Marktech’s SWIR LEDs are designed to meet the highest standards of quality and reliability. Experience the unseen with SWIR LEDs, unlocking new possibilities in the invisible spectrum.

The SWIR wavelength range also requires specialized optical detectors, as standard silicon detectors have a maximum sensitivity limit of approximately 1100nm. Marktech produces a line of 1.7µm and 2.6 µm InGaAs detectors optimized for sensing light in the SWIR wavelength range. Marktech’s SWIR LEDs satisfy a growing need for high-speed light emission in ranges not easily seen by standard detectors.

These detectors can be obtained as individual discrete components or combined with a silicon sensor to cover the complete spectrum of light from the visible to the SWIR range. Marktech also offers the option to produce multi-element devices with emitter and detector chips in the same package.

SWIR light is at the boundary between visible and thermal imaging, and this spectral range has unique properties. As a result, the market for SWIR devices is increasing. They are being used in a variety of applications, including produce inspection, security, surveillance, anti-counterfeiting, and biomedical.

SWIR LED Features

High Penetration Capabilities

SWIR LEDs can see through fog, smoke, and dust and even penetrate certain materials, making them indispensable for industrial quality control, security, and search and rescue operations.

Unmatched Image Clarity

Imaging with SWIR LEDs can provide more explicit images than NIR LEDs in low-light conditions, enhancing the capabilities of imaging systems in industrial, medical, and security applications.

Versatility

With wavelengths ranging from 1000nm to 3000nm, our SWIR LEDs are suitable for various applications, from scientific research to commercial and industrial use.

Energy Efficiency

Designed for minimal power consumption, these LEDs offer an environmentally friendly solution that reduces operational costs.

Durability

Built to last, Marktech SWIR LEDs are available in hermetic packaging to ensure a longer lifespan, reducing the need for frequent replacements and maintenance.

Eco-Friendly

Compliant with environmental regulations, our SWIR LEDs are safe to use and contribute to a greener planet.

SWIR LED Applications

Medical Diagnostic Devices

SWIR bio fluorescence and absorbance can be used to analyze urine and blood chemistry analysis for early detection and measurement of critical biomarkers (sugar, cholesterol/lipids, etc.) of disease and underlying health conditions. SWIR LEDs combined with SWIR cameras can detect cancerous, or diseased tissue to differences in SWIR LED light absorption, which does not occur in the visible wavelength range.

Smoke, Fog, & Night Vision

SWIR LEDS allow InGaAs photodiode-based imagers to see through smoke, fog, dust, sand storms, clouds, rain, plastics, and certain organic materials, which is useful in military, firefighting, and police applications. SWIR imagers and detectors work equally well at day and night, unlike thermal imagers, which “bloom” or are blinded during daylight.

Short-Haul Fiber Optic Communications

1550nm SWIR light is the most common wavelength in fiber optic communication systems. 1550nm SWIR LED emitters paired with 1.7µm can provide components for transmitters and receivers in short-haul optical communications. SWIR LEDs and InGaAs quadrant photodiodes also find applications in short-range free-space communication systems. For longer distances, lasers are used in combination with photodiodes.

Silicon wafer inspection systems

SWIR light can pass through silicon, enabling the detection of invisible subsurface flaws using visible light sources.

Presence and Level Sensors

Depending on the specific SWIR LED light wavelength, SWIR light can be absorbed by, reflected from, or transmitted through a material, polymer, powder, fluid, chemical, or other media. SWIR wavelengths, where the material is highly absorbed SWIR light or where the material appears opaque or non-transparent, allow for the sensing of the presence or level of a media through a glass or plastic container or vessel. SWIR light is passed through the container, and InGaAs photodiode or SWIR cameras detect the light transmitted to gauge level or presence. In applications with open containers non-transparent to the SWIR wavelength required to sense the media, detection can be accomplished by transferring through the top opening in the vessel. Water presence and level can be sensed through plastic or glass containers using 1450nm LEDs. Water will absorb 1450nm SWIR light and appear dark. 1700nm SWIR light will enable the detection of the presence and level sensing of oils and fats. Level sensing of ethyl alcohol or ethanol is accomplished with a 1500–1600 nm LED light source. Optical bandpass filters might be required in some of these applications.

Horticulture, Agriculture, and Food Inspection

SWIR light enables the detection of spoilage and bruises on fruit and disease on plants before signs show up in the visible spectral range. SWIR LEDs and imagers mounted on drones or aircraft can also monitor crop health and moisture content and predict yield by analyzing the reflected SWIR light from crops.

Optical Sorting

SWIR LEDs can detect different types of plastics, foods, inorganic materials, or organic materials in sorting applications. For instance, stones are sometimes mixed in with grains and seeds; these could be sorted out with SWIR LEDs combined with an InGaAs photodiode. Roasted coffee beans have a lower moisture level than green or partially roasted beans. A 1450nm LED light source and a SWIR photodiode detector image could sort beans by roasting level.

Painting Restoration / Artwork Examination

SWIR light and imaging has become an essential art restoration and authentication tool. SWIR LED light can allow art experts and curators to image underdrawings or pentimenti (hidden layers of paint in paintings). The SWIR analysis can help understand how the artworks were created and validate authenticity. And authentication.

Anti-counterfeiting

SWIR can detect unique SWIR fluorescent pigments embedded in currency or documents. It can also detect counterfeit materials and chemical substances that should not be present in a product or document.

Water and Moisture Sensors

Water has high absorption peaks at 1450nm, 1950nm, and 2600nm to 2800nm SWIR wavelengths. 1450nm SWIR LEDs are the most commonly used SWIR LEDs for water and moisture detection because 1450nm SWIR light can be detected with 1.7µm InGaAs photodiodes. Marktech’s 2.6µm InGaAs photodiodes could detect all three absorption peaks at 1450nm, 1950nm, and 2600nm to 2800nm.
