High sensitivity modules of easy-to-use
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.
