Sensors Unlimited - UTC Aerospace Systems, 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:

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 — UTC Aerospace Systems, 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 — UTC Aerospace Systems took some time out on day two of the Photonics West exhibition to catch us up on the relaunch of their InGaAs linear arrays, an update on the export classifications of a 320x256 SWIR camera, and a quick refresher on their standard suite of SWIR cameras.
Applications engineer Curt Dvonch took time out of day one of the DSS exhibition to give us a closer look (it’s small, you may have to squint) at the new 320CSX Micro SWIR camera and walked us through some of its more notable features.
Doug Malchow with Sensors Unlimited Inc., a UTC Aerospace Systems company, kicks off our BiOS and Photonics West video coverage by showing us some SWIR imagery and telling us about some new and exciting developments to their line of cameras.
A team of researchers at Purdue University’s Earth, Atmospheric, and Planetary Sciences Department recently tested the practicality of using shortwave infrared (SWIR) imaging for improving the detection of poorly-visible tornadoes in supercell thunderstorms. The team turned their attention to the Churchill Navigation ION digital recorder. The recorder’s ION and CameraLink adapter allowed the team to quickly connect and record video and metadata simultaneously from two different types of cameras; a SWIR camera provided by Sensors Unlimited and a visible-light camera.
InGaAs is an alloy of gallium arsenide and indium arsenide, and is a III-V compound semiconductor. Creating this material is a complicated process, so why go through all the trouble? This article discusses InGaAs in detail and offers benefits for using this technology for SWIR and other imaging applications.
The U-2 spy plane is the leading reconnaissance platform for the United States with the ability to see at great lengths inside national borders with a closed airspace. The camera used in today’s U-2, SYERS, uses electronic sensors to see in both the mid-wave infrared (MWIR) band (thermal energy) and the short wave infrared (SWIR) band (reflected light). It is the SWIR band that gives the SYERS its remarkable atmospheric penetration capability in reflected light.
The development of InGaAs sensors has enabled the practicality of using the shortwave infrared (SWIR) spectrum for imaging applications. This article discusses the basics of SWIR imaging, and the benefits of using InGaAs technology and its use with thermal imaging.
Long wave infrared (LWIR) and mid-wave infrared (MWIR) sensors and cameras have been used in military settings for detecting human activity through thermal emissions. Using the short wave infrared (SWIR) portion of the spectrum extends unique capabilities that often compliment LWIR and MWIR imaging. Until recently, the only way to see in this part of the spectrum was to use large, cryogenically cooled sensors. However, Sensors Unlimited of Princeton has produced small, uncooled cameras using the new indium gallium arsenide (InGaAs) semiconductor material.
InGaAs pixel chips are utilized in various products including 2D NIR/SWIR cameras, NIR/SWIR linear arrays and avalanche photodiodes (APDs), which are widely used in surveillance, night-vision devices, industrial machine vision, process control, laser beam profiling, scientific instrumentation and medical imaging applications. This application note presents the process of creating NIR pixel chips starting at the crystal growth of semiconducting InGaAs on an InP substrate wafer to the product inspection.
The GEM G2S is an additional multifunctional imaging device (sold separately) that upgrades the GEM III to a day/night short wave infrared (SWIR) imager. The additional SWIR capabilities include visibility through haze, smoke, and dust for long range ISR, image SWIR markers and beacons, and enhanced situational awareness.
The GEM III is a multifunctional night vision device with a wide variety of configurations for an array of cameras, camcorders, lenses, and scopes for covert surveillance operations. Features include a Detachable Picatinny Rail, precision optics for high-resolution imagery, genuine OEM components for ensuring compatibility, and the ability to maintain lens control and lens-to-camera communication.
The large format 640 x 512 pixel 640SDX-1.7RT InGaAs room temperature solid-state camera allows users to capture images in the Short Wave Infrared (SWIR) range of 0.9 to 1.7 ,m. Its high resolution and high sensitivity provide real-time night-glow-today light imaging for passive surveillance and use with lasers.
These high-speed 640SDWH and 640SDWHVis InGaAs room-temperature 640 x 512 pixel solid-state cameras allow users to capture full-sized images at 109 frames per second (fps) or smaller Regions of Interest (ROI) at over 15,000 fps.
