INFRARED DETECTOR
PbS photoconductive detector
P2532-01, P2682-01
Infrared detectors utilizing photoconductive effects
Features
Makes PbS cells useful in a wide range of applications
including radiation thermometers and flame monitors
l
High sensitivity
l
Large active area
l
Low price
l
Lower temperature detection limit: 100 藲C
l
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
l
Room temperature operation
