HgCdTe (MCT) Photovoltaic Detector

2.0 – 13.0 µm, two-stage thermoelectrically cooled, multiple junction

PVM-2TE-10.6 is two-stage thermoelectrically cooled IR photovoltaic multiple junction detector based on sophisticated HgCdTe heterostructure for the best performance and stability. The detector is optimized for the maximum performance at λopt = 16.6 μm. It especially useful as large active area detector operating within 2.0 to 13.0 µm spectral range. 3° wedged zinc selenide anti-reflection coated (wZnSeAR) window prevents unwanted interference effects.

Spectral response (Ta = 20°C)
