HPPD-M-B™ Amplified MCT Photodetector

HealthyPhoton's TEC cooled MCT Amplified Photodetector is a highly sensitive photovoltaic HgCdTe (mercury cadmium telluride. MCT) detector for sensitive detection of photons in the mid-IR spectral range from 2 to 12 µm.

The detector output can be DC or AC coupled. A multi-stage semiconductor thermoelectric cooler (TEC) is equipped to ensure the active area operating at a temperature ~190K, thereby minimizing the effect of thermal noise. The detector package adopts aluminum alloy materials, which shields the working environment from electromagnetic interference and also effectively dissipates heat.
