These devices combine a dewar type detector with a compatible preamplifier, and easily operate to detect infrared radiation just by connecting to

a DC power supply. InGaAs, InSb and MCT (HgCdTe) detectors are provided as standard devices (liquid nitrogen cooling). Custom-designed

devices with different active areas, FOV or amplifier gain, etc. are also available to meet your specific needs.

Features

l Compact integral detector unit

l Optimum connections between the detector element and pre-

amplifier allow amplified signals to be easily obtained.
