InAs/InAsSb superlattice four-stage TE cooled optically immersed photovoltaic infrared detectorPVIA-4TE-13-1×1-TO8-wZnSeAR-36
PVIA-4TE-13-1×1-TO8-wZnSeAR-36 is a four-stage thermoelectrically cooler IR photovoltaic detector based on InAs/InAsSb superlattice heterostructure. It enables the detection of radiation in the range from 2.2 μm to 13.6 μm. The detector element is monolithically integrated with the hiperhemispherical GaAs microlens in order to improve the performance of the device. The detector is mounted in the TO8 package with a 3 deg. wedged zinc selenide anti-reflection coated window. It is mercury and cadmium-free and is fully compliant with the RoHS Directive.
