InAs room temperature photovoltaic infrared detector
PVA-3-d1.2-SMD-pAl2O3-115
PVA-3-d1.2-SMD-pAl2O3-115 is a room-temperature IR photovoltaic detector based on InAs heterostructure. It enables the detection of radiation in the range from 1.3 μm to 3.6 μm. The detector has a surface-mount design allowing for easy integration into electronic systems and making it more practical for many applications. The planar sapphire window protects against mechanical damage and environmental influences. This detector is mercury and cadmium-free and is fully compliant with the RoHS Directive.
