Description

This module consists of the detector (474 321) with a PIN photodiode and is mounted on top of the pivot arm of the modules (474 121, 474 154). By turning the arm the angle resolved intensity distribution either of the laser diode or the fibre output can be measured. The module is connected to the signal conditioner box (474 306) where a BNC socket is provided to connect the output either to an oscilloscope or digital multimeter.
