PbS photoconductive detector

Infrared detectors utilizing photoconductive effects

Features

● Room temperature operation

Makes PbS cells useful in a wide range of applications

including radiation thermometers and flame monitors

● High sensitivity

● Large active area

● Low price

● Lower temperature detection limit: 100 ˚C

● Thermoelectrically cooled types

Cooling a PbS cell increases sensitivity and improves

S/N, so cooled types are widely used in precision

photometry such as in analytical instruments.

Applications

● Radiation thermometers

● Flame monitors

● Water content analyzers

● Food ingredient analysis

● Spectrophotometers
