HgCdTe (MCT) Photovoltaic DetectorPVMI-2TE-8
2.0 – 9.8 µm, two-stage thermoelectrically cooled, optically immersed, multiple junction
PVMI-2TE-8 is two-stage thermoelectrically cooled IR photovoltaic multiple junction detector based on sophisticated HgCdTe heterostructure for the best performance and stability, optically immersed in order to improve parameters of the device. The detector is optimized for the maximum performance at λopt = 8.0 μm. It especially useful as large active area detector operating within 2.0 to 9.8 µm spectral range. 3° wedged zinc selenide anti-reflection coated (wZnSeAR) window prevents unwanted interference effects.
