MCT12 Dewar-Cooled Photodiode (2-12µm)

The MCT12 cryogenically cooled mercury cadmium telluride takes high responsivity into the LWIR. Housing a 2x2mm active area MCT photodiode (2-12µm), the DH_MCT12 is operated in the photoconductive mode with the dedicated 475 ultra-low noise pre-amplifier module. Using an optically chopped input, the signal generated by this detector is best measured by the 496 DSP lock-in amplifier. Operation in the cryogenic mode offers ultimate sensitivity and low noise performance.
