InSb photovoltaic detector
P5968/P4247 series
High-speed response, low-noise photovoltaic detector
P5968/P4247 series are photovoltaic detectors having high sensitivity in the so-called atmospheric window at 3 to 5 µm. Custom devices are also
available to meet your special request.
Features
Applications
Cooling hold time: 8 hours
Thermometers (radiometers)
Thermal imaging
Remote sensing
Gas analysis
FTIR
Spectrophotometry
Repumpable metal dewars (liquid nitrogen cooling)
allow 8-hour hold time. Starling cooling type without
pour-filled liquid nitrogen is also provided.
Built-in preamp type available
Built-in preamp allows high precision photometry.
