Large optical disk and semi-circular lens

Estructura del mecanismo
Función	This small optical apparatus contains a metal support for holding a lamp. It has a graduated disc on which the diopters are placed. Each diopter is held in place by a screw in its centre. The disc can turn, and it is thus possible to measure the angles formed by the incident, refracted and reflected rays. Here the device is mounted with a semi-circular prism.
