HAMAMATSU P3207-07

PbSe photoconductive detectors
P9696 series
P3207-07
Infrared detectors with fast response and
high sensitivity in 5 m wavelength band
Compared to other detectors used in the same wavelength regions, PbSe photoconductive detectors have faster response and
can operate at room temperature, making them widely used in gas analyzers, etc. Cooling these detectors increases the sensitivity and improves the S/N. So cooled type PbSe photoconductive detectors are widely used in high-precision photometry such as
for analytical instruments.

Increasing the chopping frequency reduces the
1/f noise and results in an S/N improvement. The
S/N can also be improved by narrowing the noise
bandwidth using a lock-in amplier.
