InAsSb room temperature photovoltaic infrared detectorPVA-5-d1-SMD-NW/pAl2O3-115
PVA-5-d1-SMD-NW-115 and PVA-5-d1-SMD-pAl2O3-115 are uncooled photovoltaic IR detector based on InAsSb heterostructure for optimal performance and stability. It enables the detection of radiation in the range from 2.0 μm to 5.6 μm. The diameter (dA) of its active element is 1 mm. The detector is available in the SMD package without a window or with a planar sapphire window (pAl2O3).
