Mercury cadmium telluride (HgCdTe) thermoelectric cooled photoconductive mid infrared photoconductive detector 2.0-15um

The amplification detector is a thermoelectric cooled photoconductive HgCdTe (mercury cadmium telluride, MCT) detector. This material is sensitive to light waves in the mid infrared spectral range of 2.0 to 15 μ m. The semiconductor cooling chip (TEC) uses a thermistor feedback circuit to control the temperature of the detector element at -30 ° C, thereby reducing the impact of thermal changes on the output signal Transform. To achieve excellent results, we recommend connecting the output cable (not included) to a 50 ohm terminal. Due to the AC coupling of the detector, it requires a pulse or chopper input signal. AC coupled detectors will not see uncracked DC signals because they are sensitive to changes in intensity rather than intensity.
