Room Temperature HgCdTe

Infrared Associates, Inc. can now provide Room Temperature HgCdTe detectors covering the wavelength range from 1µm to 6µm.  These detectors offer both high sensitivity and ease of operation.  They are offered in a range of packaging options.  In addition, for those applications in which temperature drift is undesirable, resulting in changes in detector performance*, thermal stabilization can be accomplished by mounting the detector element on a single stage TE cooler.  This will allow the detector to maintain a temperature of 20-25 degrees C over a wide range of ambient temperatures while ensuring stable detector performance.

* For every degree increase in ambient temperature, there is a corresponding decrease  of ~2% in D*peak!
