InAsSb superlattice four-stage thermoelectrically-cooled optically immersed photovoltaic infrared detectorsPVIA-4TE-13-1x1-TO8-wZnSeAR-36

PVIA-4TE-13-1x1-TO8-wZnSeAR-36 is a four-stage thermoelectrically cooled (4TE) photovoltaic IR detector based on InAs/InAsSb superlattice heterostructure for optimal performance and stability, optically immersed to enhance the parameters. It enables the detection of radiation in the range from 2.0 μm to 13.6 μm. Its optical area (A_o) is 1 mm × 1 mm. The detector is available in the TO8 package with a 3 deg. wedged zinc selenide anti-reflection coating window (wZnSeAR) to prevent unwanted interference effects.
