HgCdTe (MCT) Photoconductive DetectorPC-4TE-14
1.0 – 16.0 µm three-stage thermoelectrically cooled
PC-4TE-14 is four-stage thermoelectrically cooled IR photoconductive detector based on sophisticated HgCdTe heterostructure for the best performance and stability. The device is optimized for the maximum performance at λopt = 14.0 μm. The device should operate in optimum bias voltage and current readout mode. Performance at low frequencies is reduced due to 1/f noise. 3° wedged zinc selenide anti-reflection coated (wZnSeAR) window prevents unwanted interference effects.
