Two or four single lead-salt detector elements are assembled within a single TO-39 or TO-8 housing each with its own IR optical filter, supplied from either one of many LASER COMPONENTS’ standard optical filters or a custom designed optical filter. Free issue filters or windows can also be used. The popular detector element of choice measures 1 mm x 1 mm square. Single channel detectors usually employ 2 mm x 2 mm square elements.
With a spectral response from 1 - 5.2 µm these high detectivity detectors are ideal for non-dispersive infrared (NDIR) simultaneous gas sensing. Popular gases include CO2, CO, HC and a reference channel typically at 4 µm.
For increased signal to noise, thermal electric coolers (TECs) with one, two, three or even four stages can also be included.
Due to their high response speed, typically exhibiting a 200 µs time constant, these detectors are ideal for fast events, such as the detection of hot spots in train wheels, car engine combustion efficiency, electro-mechanical converters, and incinerator efficiency for example.
