Photoconductive sensors made of mercury cadmium telluride (MCT) still offer the highest possible sensitivity in the middle IR range. The photovoltaic version of HgCdTe detectors is ideally suited for direct current and low frequency applications.
HgCdTe is a ternary semiconductor material. Its composition determines the cut-off wavelength.
The application field is equal to InSb, but without LN2 cooling. The typical 1/f noise does not occur with PV MCT detectors and are therefore ideally suited for distributed current and low frequency a
