Beam separator : POD060210

This device enables the incident beam to be divided into two emergent beams of identical light intensity, through one half-reflecting plate & one mirror.
The separator plate is fixed, while the mirror is fitted upon one adjustment knob, enabling the User to make the reflected beam emergence angle to vary.
It is also possible to vary the path difference between the two emergent beams.
The assembly is carried on one Ø 10 mm rod.
