Photoconductive detector
WebInfrared Photoconductive Detectors Infrared light at wavelengths sometimes beyond 5 μm can be detected with lead salt detectors, e.g. containing lead selenide (PbSe) or lead sulfide (PbS). Such devices are not fabricated with epitaxial growth, as e.g. InGaAs photodiodes, but rather by deposition of thin polycrystalline films.
