Princeton Infrared Technologies, Inc. (PIRT) is a fabless infrared company focused on design, test, and final assembly of infrared imaging and detection products specializing in InGaAs detector arrays. These detector materials are used to detect light beyond what our eyes see in the Near Infrared as well as Short Wave Infrared (900nm-1700nm) versus visible light (400-750nm). Detectors and cameras are similar to cell phone cameras except they see infrared light that our human eyes do not see. There are numerous applications for imaging and detecting light beyond what humans can image with our eyes including applications that need to detect moisture, temperature, or specific laser wavelengths, i.e. laser designators for dropping bombs and eye-safe lasers used in range finders. InGaAs is fabricated in what is called a III-V semiconductor fab which is very similar to where they manufacture silicon integrated circuits for computer chips, but the manufacturing plant is for different materials than Silicon like InGaAs or GaAs. PIRT will leverage the many larger III-V fabrication facilities that are now capable of building InGaAs detector arrays. This will be a significant cost driver since todays InGaAs imager producers currently maintain their own semiconductor fabrication facility, which are only at partial capacity due to the relatively small volumes being sold resulting in higher cost.
