HgCdTe (MCT) Specifications

Hg1-xCdxTe (mercury cadmium telluride) is narrow direct bandgap alloy with a tunable bandgap spanning the shortwave infrared to the very long wave infrared regions. HgCdTe is the only common material that can detect infrared radiation in both of the accessible atmospheric windows. These are from 3 to 5 µm (the mid-wave infrared window, abbreviated MWIR) and from 8 to 12 µm (the long-wave window, LWIR).HgCdTe is a common material in photodetectors of Fourier transform infrared spectromet
