Sensors Unlimited Inc – A part of Collins Aerospace
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.
