Type II Superlattice Photoconductive DetectorPCAS-3TE-12-0.1×0.1-TO8-wZnSeAR-70

1.6 – 14.4 µm, three-stage thermoelectrically cooled

PCAS-3TE-12-0.1×0.1-TO8-wZnSeAR-70 is a Type II superlattice three-stage thermoelectrically cooled IR photoconductor, with excellent parameters. 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.
