ABOUT US
Sensors Unlimited Inc., An RTX Company
Sensors Unlimited is a major supplier of Indium Gallium Arsenide (InGaAs) technology, products, and shortwave infrared (SWIR) imaging solutions. Their technology is used in applications such as security and surveillance, military, machine vision, photovoltaics, medical, spectroscopy, semiconductor inspection, instrumentation, thermography, and telecommunications.
Sensors Unlimited has continued to push InGaAs technology forward, today producing not just single point light sensing diodes, but InGaAs one-dimensional linear arrays and two-dimensional focal plane array cameras.
SWIR Area Cameras
Sensors Unlimited offers a variety of compact, highly sensitive SWIR area cameras that are well suited for applications that require real-time daylight to low-light imaging in wavelengths ranging from 0.4um to 1.7um. Resolutions up to 1.3MP and multi-mode laser tracking and decoding products are available.
Linescan Cameras
SUI’s Linescan cameras deliver line capture rates up 147,000 lines per second for a wide range of applications including Optical Coherence Tomography, Machine Vision for inspection, sorting and / or monitoring of continuous processes and inspection of silicon wafers and through polished silicon blocks.
Linear Photodiode Arrays
SUI products are available with cut-off wavelengths of 1.45, 1.7, 2.2 or 2.6 microns. All sensors exhibit reduced dark current and improved uniformity. Array lengths of 256, 512, or 1024 pixels, with widths of 1/4, 1/2, or 1 inch are available with antiblooming to prevent charge overflow from saturated pixels.
Soldier Handheld Systems
SUI Handheld systems provides distinct advantages over other available viewer technologies including visible (CMOS), thermal, and night vision (I2) systems. Battlefield laser aim points are easily identified through conditions that degrade other systems including haze, smoke and dust. The field-ready SPS+MMT provides high resolution video a and simultaneous tracking and decoding of 3 pulsed battlefield lasers day and night.

INDUSTRIES & APPLICATIONS
As the U.S. continues to increase its security at border crossings, airports, and other points of entry, biometrics will play an important role. SWIR cameras can help identify disguises at the border and therefore supplement security efforts.
Manufacturers of glass hollowware have long sought a way to pick out defective product at the hot end of their process, while the pieces are still above 200ºC. At that glass inspection stage, rejects are identified, then shunted aside and reprocessed efficiently, greatly reducing scrap.
Whereas past reconnaissance needs were more strategic, today's needs are highly tactical, demanding a high level of persistence and the ability to identify individual humans in the field of interest. In recent years, the exceptional capabilities of short wave infrared (SWIR) technology have made it the next generation of imaging technology for ground, airborne, and space technology.
Examine the world of InGaAs linear arrays and detectors for NIR and SWIR spectroscopy and various applications and advantages of spectroscopy, including mineral analysis and material identification.
Contactless machine-vision inspection using photoluminescence (PL) imaging with shortwave infrared (SWIR) cameras can help solar cell producers improve both efficiency and quality of their photovoltaic products. Inspection of silicon bulk ingots, sliced wafers, processed layers, and complete photovoltaic cells is possible with SWIR imaging.
Multi-spectral electroluminescence and SWIR imaging can be used to separately inspect multi-junction uniformity and relative output.
By using the 1.05 µm central wavelength, instrumentation companies are developing systems to image deeper through the retina into the blood vessel layer to diagnose eye diseases and monitor treatment.
The GHGSat’s microSat circles the Earth every 90 minutes, collecting infrared images. Find out how data from the microSat enables industries to monitor their own carbon dioxide and methane emissions.
