Sensors Unlimited, a part of Collins Aerospace, is the world’s leading manufacturer of indium gallium arsenide (InGaAs)-based imaging products. As renowned experts in shortwave infrared (SWIR) imaging, Sensors Unlimited, Inc. introduced the world to the concept of imaging in the shortwave IR spectrum with simple, compact, and uncooled cameras.
We offer a wide variety of InGaAs-based products, such as high performance, near-infrared (NIR) and SWIR cameras, and 1- and 2-dimensional focal plane arrays for use in military, aerospace, biomedical, commercial and industrial applications. Our in-house indium gallium arsenide III-V foundry features Class 100 clean rooms and an MOCVD epitaxial growth wafer fab, plus a 20,000 square foot detector manufacturing facility.
The advanced InGaAs detector technology allows imaging in the SWIR without the necessity of an external cooling system. Other benefits of our proprietary sensor technology are low power consumption and the ability to image at high frame rates, a remarkable advantage over current uncooled microbolometer technology. Our NIR cameras deliver what thermal imagers cannot – clear, lifelike detection in daylight or lowlight. Small and compact, they operate at room temperature with no moving parts and can image through glass and plastic using off-the-shelf glass optics. Because our InGaAs cameras have non-uniformity corrections (NUCs) that last for the lifetime of the cameras, they do not need NUCs in the field, making operation simpler.
InGaAs arrays and imagers are ideal for a wide variety of military, industrial, biomedical, telecommunications, scientific and commercial applications. These include:

Doug Malchow with Sensors Unlimited – A part of Collins Aerospace discusses SWIR imaging and why you should care about it. Watch the video for information on SWIR technology and how it can benefit your research – particularly where military, security, and industrial applications are concerned.
At DCS 2017, Doug Malchow took us through a presentation on when and why you should use SWIR (short-wave infrared) technology for imaging applications.
This year at Photonics West, Sensors Unlimited familiarized us with their export compliance guidelines for their line of cameras.
At SPIE’s DCS 2016 exhibition, Sensors Unlimited – A part of Collins Aerospace, Brendan Murphy, spent some time with Photonics Online to school us up on the three primary things one should consider before purchasing a SWIR imager — resolution, global availability, and cost.
Doug Malchow with Sensors Unlimited – A part of Collins Aerospace discusses the relaunch of his company's InGaAs linear arrays, provides an update on the export classifications of a 320x256 SWIR camera, and shares a quick refresher on their standard suite of SWIR cameras.
The Non-ITAR, Low-Cost Micro-SWIR 640CSX InGaAs cameras for military applications feature 640 x 512 pixel resolution, a 12.5 µm pitch, high sensitivity, and Automatic Gain Control (AGC). They also offer 30 or 60 frames per second (fps) full frame rate with 1.5 W power consumption. Exposure times are user configurable from 200 μs to 33 ms, and scan modes are continuous with user configurable trigger modes.
As the US continues to increase its security at border crossings, airports and other points of entry, biometrics will play an important role. Fingerprints and other direct contact means will become final identifiers of persons.
The 1024-LDH2 is a high-speed 1024-pixel linescan InGaAs camera that increases the A-line rate to 91,911 lines per second to enable spectral domain Optical Coherence Tomography (OCT) to capture detailed 3-D volumes of the retina, nerve head and choroid layer in a blink of the eye. For 1.31 μm SD-OCT, diode array-based OCT systems offer superior phase stability for doppler or polarization-sensitive OCT.
The SPS+MMT, a SWIR Pocket Scope + Multi Mode Tracker, is designed to provide high resolution video with laser tracking and decoding of up to 3 independent sources. Available capabilities include simultaneous tracking and decoding, out of band SWIR imaging (0.7 to 1.7 µm), enhanced battle damage assessment, and reduced fratricide and collateral damage.
The compact SPS (SWIR Pocket Scope) field-ready viewer is designed to provide high resolution video within day time and nighttime operations. The SPS makes it easy to identify battlefield laser aim points, reducing both the time to engage targets and the risk of fratricide and collateral damage. This imaging system’s performance is not degraded with bright flashes. Its versatility makes it helmet and weapon mountable with an adjustable reticle, digital zoom, media recording, and compatibility with other Sensors Unlimited lenses.
Sensors Unlimited – A part of Collins Aerospace introduces their new LDM series of compact, InGaAs SWIR line scan camera for machine vision, sorting, & solar inspection. The 1024LDM line-scan camera features high resolution, 1024-pixel imaging in the shortwave infrared (SWIR). Its square pixels are ideal for inspection of polished silicon blocks, ingots, or wafers, hot glass bottles, and for use on continuous-process lines that apply transparent coatings which can be ‘seen’ in the SWIR spectral region.
By using the 1.05 µm central wavelength, instrumentation companies are now developing systems to image deeper through the retina into the blood vessel layer (called the choroid) to diagnose eye diseases and monitor treatment.
The Salt Lake City Valley in Utah sometimes experiences trapped air pollution in the atmosphere that severely reduces ground visibility. This article demonstrates the difference between using visible light and SWIR cameras to provide greater detail in imaging, even in challenging conditions.
