Four-quadrant APD modules

Four-quadrant APD modules

Model: GD5242Y/ GD4243Y

Short Description:

It consists of four same units of Si avalanche photodiode with pre-amplification circuit that enables weak current signal to be amplified and convert into voltage signal to achieve the conversion process of photon-photoelectric-signal amplification.
