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 SBIR Phase II Award for Coherent LADAR Detectors

POSTED 05/01/2019

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 Small Business Innovation Research (SBIR) award. The Phase II SBIR contract with Air Force Research Laboratory (AFRL) will fund the development of detector arrays for coherent laser detection and ranging (LADAR). Princeton Infrared Technologies will focus on developing detector arrays using multi-quantum well materials enabling detection from 0.9 to 2.4 µm with low-dark current and high-quantum efficiency. This will enable a new generation of high-resolution cameras that can image at, or near, room temperature while allowing high sensitivity in the shortwave-infrared spectrum. The new arrays will be high speed, enabling next-generation coherent LADAR using arrays versus single-element detectors.

The SBIR Phase II project is a $750,000, 2-year effort that will concentrate on new material development. Princeton Infrared Technologies and its’ subcontractors will be conducting research on the development of new multi-quantum well materials, in addition to strained-superlattice materials manufactured on indium phosphide (InP) substrates. The R&D work will be supported by the Air Force Research Laboratory at Wright-Patterson Air Force Base, Ohio.

President of Princeton Infrared Technologies, Martin H. Ettenberg, Ph.D., notes, “Utilizing multi-quantum well materials will enable high-sensitivity detectors to image beyond what lattice-matched InGaAs detectors can detect in the SWIR range. These next-generation detector arrays will benefit long-range LADAR used by the Air Force to identify targets. Current systems require cryogenic cooling while these materials will not, thus vastly lowering costs, size, weight, and power. The material development will also be useful in the commercial sector for spectroscopy and industrial imaging.”
