Type II Superlattice Photoconductive Detector

PCIAS-3TE-12-1×1-TO8-wZnSeAR-36

1.6 – 12.6 µm, three-stage thermoelectrically cooled, optically immersed

PCIAS-3TE-12-1×1-TO8-wZnSeAR-36 is a Type II superlattice three-stage thermoelectrically cooled IR photoconductor, with excellent parameters. Detector element is monolithically integrated with hyperhemispherical GaAs microlens in order to improve performance of the device. Photoconductive detector 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 window (wZnSeAR) prevents unwanted interference effects. For detection of CW radiation, using of optical chopper system is recommended. This detector does not contain mercury or cadmium and is compliant with the RoHS Directive.
