Mirrors are an important component of most optical assemblies. Mirrors are used here that are coated with a reflective layer on the front. This prevents unwanted reflections on the front and back of the glass plate.
There are two variants of mirror suspension in the set, as well as the combination with a piezo element:
- The suspension at a 90° angle is used for
- The suspension at a 45° angle is used for
- The combination of suspension at a 90° angle with a piezo element can be used for
- investigation of the effects of the smallest changes in distance in the arms of the Michelson interferometer on the interference pattern.
90° mirror
Below you will find information on assembly and possible experiments.
Assembly
The adjustment works in the same way as for the laser diode, the LED and the piezo mirror module.

Special Features
The soldering points on the piezo element are sensitive to mechanical stress. A piece of shrink tubing directly behind the soldering points can serve as strain relief.
