1.6-10.5 µm; Active Area 0.01, 1 mm²; Responsivity 0.04-4.4 A/W; Detectivity 1.2x108-9.0×109 cm·Hz1/2/W; Resistance 28-5,000 Ω; Package TO39, TO8 Vigo System develops and produces a variety of MWIR and LWIR type II superlattice (T2SL) photoconductive (PC, PCAS series) and photovoltaic (PV, PVAS series) IR detectors, operating at room temperature or thermoelectrically cooled. These detectors achieve excellent parameters without cryogenic cooling (LN2). They do not contain mercury or cadmium and are complying with the RoHS Directive. The PCAS series of InAs/InAsSb type II superlattice photoconductive IR detectors contains 2-stage (PCAS-2TE series) or 3-stage (PCAS-3TE series) thermoelectrically (TE) cooled detectors with excellent parameters. Photoconductive detectors should operate in optimum bias voltage and current readout mode. Performance at low frequencies is reduced due to 1/f noise. A 3° wedged zinc selenide anti-reflection (AR) coated window (wZnSeAR) prevents unwanted interference effects. Some models additionally feature anti-reflection (AR) coating applied to the active element. For detection of CW radiation, the use of an optical chopper system is recommended. The PVAS series of InAs/InAsSb type II superlattice photovoltaic IR detectors contains uncooled or 2-stage (PVAS-2TE series) thermoelectrically (TE) cooled detectors with excellent parameters. The PVAS-2TE series features a 3° wedged sapphire window (wAl2O3) preventing unwanted interference effects.
