P2532-01 Datasheet, PDF (1/4 Pages) Hamamatsu Corporation – PbS photoconductive detector

INFRARED DETECTOR
PbS photoconductive detector
P2532-01, P2682-01
Infrared detectors utilizing photoconductive effects
Features
l Room temperature operation
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 ˚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 Radiation thermometers
l Flame monitors
l Water content analyzers
l Food ingredient analysis
l Spectrophotometers
Accessories (Optional)
l Heatsink for one-stage TE-cooled type
l Heatsink for two-stage TE-cooled type
l Temperature controller for TE-cooled type
l Preamplifier for PbS/PbSe photoconductive detector
l Power supply for amplifier
l Infrared detector module with preamp Cooled type
