THE STYAG PHOTODETECTOR PREAMPLIFIER MODULE

THE STYAG-CH PHOTODETECTOR PREAMPLIFIER MODULE

ü Photodetector preamplifier module on the basis of a PbSe-photoresistor array of 64 (16х4) responsive elements;

ü two-stage thermoelectric cooler (temperature difference of 70 ˚С), signal amplification over each channel, linear output;

ü hermetically sealed construction;

ü metal-to-glass package with a flat leuco sapphire input window;

ü application: devices to establish precise position of high-speed thermal objects
