InAs Photovoltaic Detector

2.4 – 3.2 µm, two-stage thermoelectrically cooled

PVA-2TE-3-0.1×0.1-TO8-wAl2O3-70 is a two-stage thermoelectrically cooled IR photovoltaic detector based on InAs alloy. It does not contain mercury or cadmium and is complying with the RoHS Directive. 3° wedged sapphire (wAl2O3) window prevents unwanted interference effects.

Spectral response (Ta = 20°C, Vb = 0 mV)

Features

  • High performance in the 2.4- 3.2 µm spectral range
  • Two-stage thermoelectrically cooled
  • Complying with the RoHS Directive
  • No bias required
  • No 1/f noise
