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.

PIRT Introduces High-Resolution, Extended Shortwave Infrared (SWIR) Camera for Beam Profiling at BiOS & Photonics West 2022

  • New T2SL thermoelectrically-cooled SWIR camera supports extended SWIR wavelength response to deliver superior beam profiling from the visible to 2050 nm using a single imager.

Monmouth Junction, NJ – January 19, 2022 - 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, introduces the 1280BPCam, an extended-SWIR response camera developed specifically for laser beam profiling. The new InGaAs/GaAsSb (InGaAs/gallium arsenide antimonide) type-II super lattice (T2SL) detector features 1280 x 1024 pixels on a small 12-µm array pitch that delivers 90 frames per second (fps) at full resolution.

The extended wavelength response of the T2SL material plus the 3-stage thermoelectric cooler (TEC) enable high sensitivity from 400 nm to 2050 nm, making it possible to image from the Visible out to the SWIR spectrum with a single imager. The high-resolution imagers are specially fabricated on 100 mm substrates to enable low-cost production.

The 1280BPCam’s advanced focal plane array integrated in the camera generates full 14-bit pixel data at high resolution which is reliably transferred by a Medium Camera Link interface. Other notable features include snapshot exposure, selectable trigger modes, and user-selectable regions of interest (ROI). Integration times range from 50 µs to greater than 16 ms. With less than 275e- read noise, high dynamic range of greater than 1000:1, plus greater than 20% quantum efficiency for 1.9 µm, the extended SWIR beam profiling detector camera is ideal for use in a variety of industrial, medical, and defense applications.

To see a live demo of Princeton Infrared Technologies’ advanced 1280BPCam for laser beam profiling, please visit booth #8371 at SPIE’s BiOS, January 22 - 23, 2022, and booth #3371 at Photonics West, January 25 - 27, 2022, Moscone Center, San Francisco.
