ABOUT US

Originally founded in 1991 as an advanced research and development company, Sensors Unlimited, Inc. quickly grew to become a major supplier of InGaAs technology, products, and shortwave IR imaging solutions.

Now as Raytheon, an RTX Business, the team operates in an ISO 9001:2015 certified fabrication facility occupying over 97,000 square feet and that includes a III-V foundry with Class 100 clean rooms and state-of-the art processes such as our MOCVD epitaxial growth and detector formation. Products built on our proprietary InGaAs platform are SWIR cameras, 1- and 2- dimensional focal plane arrays (FPAs), extended wavelength response InGaAs image sensors, alongside RTX, has the resources to custom design structures and devices for a variety of customer requirements. Current deployments include laser tracking for weapons and communication systems, covert and fixed-site surveillance, ground and air unmanned vehicle (UV) payloads, gimbal sensor assemblies, night vision and free space communications. Other applications for InGaAs technologies and imaging systems include near-infrared spectroscopy, security and surveillance, line-scan inspection, process control, laser beam profiling, microscopy, art inspection, and astronomy.

Raytheon serves customers in the commercial aerospace and defense industries. We combine complementary technology offerings and world-class engineering teams to deliver innovative solutions. The foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world.

The SUI management team has a combined total of over 75 years’ experience in the infrared detector industry, making us ready for any shortwave or near infrared imaging challenge. In addition, our highly experienced engineering staff, forty-four percent of whom hold an advanced degree, strives continually to advance our technology to the next level. In addition to its outstanding development and fabrication team, SUI relies upon its intellectual property portfolio, which consists of over 15 patents in InGaAs technology.

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.

NEWS

  • Sensors Unlimited, a Raytheon Company (An RTX Business) has launched a new website at  www.sensorsinc.com that features its world-class shortwave infrared (SWIR) cameras and components based on indium gallium arsenide (InGaAs) imaging technology.

  • The 1280JSX features a 1.3MP high resolution, high-sensitivity InGaAs imager. Designed for real-time imaging from daylight to low-light conditions, it is ideal in applications such as covert surveillance with 24/7operation, multi-laser spotting and tracking, imaging through atmospheric obscurants, DVE and integration into unmanned aircraft systems, handheld and robotic systems. VIS/ SWIR technology extends the camera’s sensitivity down to 0.5 µm wavelength response for enhanced versatility.
