8.2. Total reflex spherical reflexometer

A total reflection spherical reflexometer is an integrating sphere with an inner diameter of 200 mm and three holes:

1) for measured samples,

2) for the light source,

3) for the radiation receiver.

The purpose of the reflexometer is to measure total (specular + diffuse) reflection from the surface under investigation at an angle of 30°.
