InfraRed Associates, Inc. offers InSb/HgCdTe two colour infrared detectors for both commercial and military applications.

These detectors are constructed in the form of a sandwich and respond to different buy adjacent regions of the infrared spectrum.
The InSb/HgCdTe two colour sandwich has the top layer of InSb responding from 1µ to 5.5µ and the lower element of HgCdTe responds from 5.5µ to 125.µ.

InSb Infrared Detectors

The HgCdTe detectors can be fabricated in quadrant arrays for tracking and positioning systems, scanning systems and night vision equipment.

The quadrant arrays require a common lead between the four elements in either the X or Y direction.
