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.

The exceptional LineCam12 camera features an InGaAs linear array detecting light from 400 -1700nm

POSTED 12/20/2017

The LineCam12 is a digital linescan camera for imaging in the SWIR and visible bands (0.4-1.7mm).  It has two digital output formats USB3 Vision and Camera Link. The device can even be powered by USB3 in most applications.  The LineCam12 utilize a 1024x1 state of the art InGaAs linear array imager on 12.5mm pitch that was built for both machine vision and spectroscopy applications.

The LineCam12 is an advanced linescan camera with 14 bit digital data at 37klines/s on Camera Link output or <20klines/s with USB3.  The camera currently comes in two varieties 250mm tall pixels for spectroscopy and 12.5mm square pixels for machine vision applications.  The camera has incredible versatility enabling full wells from 75ke- to 100Me- with 128 steps of variation as well as integration times from 10ms to >150s.  On chip optical pixel binning (where every other detector is disconnected from the ROIC thus signal is captured by neighboring pixels) is available by command to trade spectral resolution for increased signal level.  Pixel skipping or binning is also available allowing for 48klines/s at 512 resolution in the same camera platform, activated by a simple command structure.  The TEC stabilized camera has 31 non-uniformity correction (NUC) tables with 15 factory set and 16 user defined tables to enable flexibility for the given environment.

This lattice matched InGaAs array is backside illuminated enabling detection from 0.4 to 1.7um with no bond pads or wires in the way of your signal and minimize stray reflections found in front side illuminated arrays with many wire bonds near the active imaging area.  The array can be customized to allow optical filters to be placed on the active detector area something that is nearly impossible in front side illuminated devices.
