The photodetector can be used for detection of laser radiation in the infrared wavelength range.
Principle of operation
The signal from InSb photoresistor operated at room temperature is enhanced by a preamplifier with multiplication factor 100 and bandpass 100 kHz.
Areas of application
Noncooled infrared photodetector can be used in scientific investigations, medicine and thermal imaging technique.
