"Ten". Bi-platform photodetector
with integrated amplifier

Bi-platform photodetector with integrated amplifier “Ten” is intended for reception and amplification of low light signal in wide range of frequency of modulation.

It consists of two photodiodes and two broadband operational amplifiers, placed in the standard case TO-5. Frequency band and factor of amplification are regulated by four external resistors. The device is steady against mechanical influences: impact up to 200g, vibration up to 30g.
