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.

The mounting flange supplied with the DH_MCT12 is compatible with the entire range of Bentham monochromators and accessories.
