ABOUT US
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.
ADVANTAGES
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.
APPLICATIONS
InGaAs arrays and imagers are ideal for a wide variety of military, industrial, biomedical, telecommunications, scientific and commercial applications. These include:
