High-Resolution, Extended SWIR Camera for Beam Profiling

Supports extended SWIR wavelength response for beam profiling from the visible to 2050 nm using single imager

Published: Wednesday, February 9, 2022 - 12:57

(Princeton Infrared Technologies: Monmouth Junction, NJ) -- Princeton Infrared Technologies (PIRT), specialists in indium gallium arsenide (InGaAs) imaging technology and affordable shortwave-infrared (SWIR) linescan cameras, visible-SWIR science cameras, and 1- and 2D imaging arrays, has introduced 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 three-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. Integration times range from 50 µs to greater than 16 ms. With less than 275 e-read noise, high dynamic range of greater than 1000:1, plus greater than 20-percent 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.
