HgCdTe three-stage thermoelectrically cooled optically immersed photoconductive infrared detectorsPCI-3TE-12-1x1-TO8-wZnSeAR-36
PCI-3TE-12-1x1-TO8-wZnSeAR-36 is a three-stage thermoelectrically cooled (3TE) photoconductive IR detector based on HgCdTe heterostructures for optimal performance and stability, optically immersed to enhance the parameters. Its specific wavelength (λspec) is 12.0 µm and its optical area (Ao) is 1 mm × 1 mm. The detector should operate in optimum bias voltage (Vb) and current readout mode. Performance at low frequencies is reduced due to 1/f noise. The detector is available in TO8 package with a 3 deg. wedged zinc selenide anti-reflection coated window (wZnSeAR) to prevent unwanted interference effects.
