CH253

CH253 optical detector module is composed of side-on PMT, power supply circuit and amplifier circuit. The current signal generated by the PMT is transformed into voltage signal after being converted and amplified.

The optical detector module can be adjusted by voltage or potentiometer to control gain, and is characterized by low noise, wide  frequency bandwidth, strong anti-interference, adjustable gain and wide dynamic range.
