INFRARED DETECTOR
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 碌m. Custom devices are also
available to meet your special request.
Features
Repumpable metal dewars (liquid nitrogen cooling)
allow 8-hour hold time. Starling cooling type without
pour-filled liquid nitrogen is also provided.
l
Built-in preamp type available
Built-in preamp allows high precision photometry.
P7751-01 (Uses P5968-060.)
P7751-02 (Uses P5968-200.)
