Indium antimonide (InSB)/MCT 2 colour detectors combine the advantages of InSb detectors with high sensitivity in the range 1 – 5.5 microns with the high sensitivity of the MCT detectors in the range up to 12.5 microns and beyond.
Principle
The HgCdTe (MCT) detector and the InSb detector are arranged at 90°. A dichroic mirror directs the shorter wavelength IR radiation to the InSb detector and the longer wavelength radiation to the MCT detector. Therefore, the best possible sensitivity is obtained over the whole IR range.
The HgCdTe element can be customised to extend its long wavelength response beyond 25mm. Custom configurations are available.
