  • Princeton Infrared Technologies Announces SBIR Phase II Award for Coherent LADAR Detectors, News Release, May 2019

    Monmouth Junction, NJ – May 1, 2019 - 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.”

  • Faces in Vision: Martin Ettenberg, Vision System Design, June 2017

    President of Princeton Infrared Technologies, Inc. Year and location founded: 2013 in Monmouth Jct., NJ. After leaving Sensors Unlimited Inc. Goodrich Corporation in 2011 I did some consulting on SWIR imagers. I was constantly being asked "Why are InGaAs detectors so expensive?" I had a standard answer about volume and custom foundries but after the fourth or fifth call I started to really think about the problem and looked at what our colleagues in the silicon imager world were doing. This became the founding principle of Princeton IR Technologies: We are a foudryless semiconductor company leveraging outside foundries with larger volumes, better equipment, and more uniform processes to drive down costs and increase quality in our imaging products.  (See page 40)

  • Princeton Infrared Technologies Receives Vision Systems Design's Gold Level Innovators Award 2017, PRLOG, April 2017


    MONMOUTH JUNCTION, N. J.  – April 4, 2017 - Princeton Infrared Technologies, Inc. (PIRT) (, announced today that its LineCam12 linescan camera, based on indium gallium arsenide (InGaAs), shortwave infrared (SWIR) detector technology, was recognized by the judges of the annual Vision Systems Design (VSD) Innovators Awards program with a Gold Level award because of its unique properties. The judging panel consisted of esteemed experts from system integrator and end-user companies.  The exceptional LineCam12 camera features the only InGaAs linear array with visible, near-infrared (NIR), and SWIR sensitivity.  By detecting light from 400 nm to 1700 nm, the new linescan camera enables machine vision (MV) and spectroscopy users the ability to see both visible, NIR, and SWIR light simultaneously, allowing hyperspectral imaging applications that would have previously required 2 or 3 cameras to achieve the same performance. The low read noise of <80e- is a factor of 4x lower than other known legacy cameras in the industry. The advanced SWIR-InGaAs 1024-element linear array can image over 37k lines per second and has a 12.5 µm pitch. With two digital outputs, USB3.0 and Camera Link®, the LineCam12 is easy to integrate into new and/or existing systems.   Martin Ettenberg, Ph.D., founder and CEO of Princeton Infrared Technologies, notes, “This is the second year in a row that we’ve received the gold level award and it’s only our second product to enter the competition! Last year, our scientific camera, the 1280SciCam was selected. This year’s award-winning LineCam12 with its wide spectral sensitivity is an ideal linear array for machine vision tasks while also serving the spectroscopy market. We are delighted to be honored again by Vision Systems Design’s Innovators Awards Program.”
