PVIA-2TE-3-1×1-TO8-wAl2O3-36

InAs Photovoltaic Detector

2.4 – 3.2 µm, two-stage thermoelectrically cooled

PVIA-2TE-3-1×1-TO8-wAl₂O₃-36 is a two-stage thermoelectrically cooled IR photovoltaic detector based on InAs alloy, optically immersed in order to improve performance of the device. It does not contain mercury or cadmium and is complying with the RoHS Directive. 3° wedged sapphire (wAl₂O₃) window prevents unwanted interference effects.
