INFRARED DETECTOR
InAs photovoltaic detector
P8079 series, P7163
High-speed, low noise photovoltaic IR detectors
InAs photovoltaic detectors cover a spectral response range equivalent to that of PbS detectors, but provide higher response speed and
lower noise.
Features
l Thermoelectrically cooled type: high sensitivity
l ^{and high-speed response}
Metal dewar type available for low light measurement
l Long-wavelength cut-off of up to 3.8 µm
l Easy-to-use detector/preamp modules available
Applications
l Gas analysis
l Infrared radiation measurement
l Infrared spectrophotometry
l FTIR
Accessories (Optional)
l Heatsink for one-stage TE-cooled type
l Heatsink for two-stage TE-cooled type
l Temperature controller
l Infrared detector module with preamp
