LEARN MORE

Princeton Infrared Technologies, Inc. (PIRT) is focused on supplying Shortwave Infrared detectors to both the commercial and defense markets. PIRT is a fabless semiconductor company focusing on design and integration. Shortwave Infrared (SWIR) Imaging using lattice matched InGaAs provides some of the lowest noise imaging material for imaging in the SWIR. Princeton Infrared Technologies, Inc. (PIRT) has detectors that image from 0.5 to 1.7µm, which are useful for a variety of commercial and defense applications. These include detecting moisture, determining plastic types, plant health, fill level, as well as imaging lasers. We sell these imagers by themselves, in packages, as well as in complete camera systems both 1D linear arrays and 2D area cameras up to 1.3Mpixles.

Princeton Infrared Technologies Announces Phase II Award from MDA to Develop Time of Flight Camera for 3D Imaging

POSTED 11/18/2020

Monmouth Junction, NJ - Princeton Infrared Technologies, Inc. (PIRT), specialists in indium gallium arsenide (InGaAs) imaging technology and affordable shortwave-infrared (SWIR) linescan cameras, visible-SWIR science cameras, and 1- and 2-D imaging arrays, announces a Phase II Small Business Innovation Research (SBIR) award from the Missile Defense Agency (MDA) to fund the development of a 128x128 on 50µm pixel pitch radiation hardened Laser Detection and Ranging (LADAR) system. Princeton Infrared Technologies will focus on developing a flash LADAR module featuring indium gallium arsenide phosphide (InGaAsP) linear mode avalanche photodiodes (APDs) optimized for detection of 1.06µm light hybridized to a custom ROIC and operated with camera electronics.  

In Phase I, PIRT developed the InGaAsP APD material structure and a unique ROIC circuit optimized for the application.

Martin H. Ettenberg, Ph.D., president of Princeton Infrared Technologies, Inc., notes, “We are excited about this Phase II research. The new APD detector structure combined with this unique ROIC design will enable an exciting space-based 3D LADAR system.”
