HgCdTe (MCT) Photovoltaic DetectorPVI-2TE-6-1×1-TO8-wZnSeAR-36

3.0 – 6.7 µm, two-stage thermoelectrically cooled, optically immersed

PVI-2TE-6-1×1-TO8-wZnSeAR-36 is two-stage thermoelectrically cooled IR photovoltaic detector based on sophisticated HgCdTe heterostructure for the best performance and stability. The device is optimized for the maximum performance at λ_opt = 6 µm. Detector element is monolithically integrated with hyperhemispherical GaAs microlens in order to improve performance of the device. Reverse bias V_b may significantly increase response speed and dynamic range. 3° wedged zinc selenide anti-reflection coated (wZnSeAR) window prevents unwanted interference effects.
