PbS Detectors Polycrystalline lead sulfide detectors (PbS) detect infrared radiation in the wavelength range between 1 µm and 3.3 µm. Description PbS detectors exhibit a higher sensitivity than PbSe detectors, by more than one order of magnitude; however, the time constant is longer. The IV-VI semiconductor PbS is a photodetector that reacts to incident IR radiation and changes its electrical resistance. These detectors are used especially when large-area detectors are required because they are significantly less expensive than comparable InGaAs detectors. The typical chip size of LASER COMPONENTS’ standard detectors is 2 mm x 2 mm. Other configurations are also available upon request.
