Photovoltaic IR detectors featuring a semiconductor element made of InAs, InAsSb, or a superlattice material. These detectors are cadmium- and mercury-free, ensuring compliance with the RoHS directive and making them suitable for the consumer market. With a spectral range spanning from 1.3 to 15.2 µm, they are widely used in demanding applications, including FTIR spectroscopy, gas detection, CBRN threats detection, CO2 laser measurements, free-space optical communication, dentistry, and glucose sensing.
