Precision Interferometer

Precision Interferometer

SKU Item Code: SK059 Category

This equipment combines the historically important Michelson interferometer, the high resolution Fabry-Perot interferometer and the useful Twyman-Green interferometer.
Measurements are precise in three classical modes of operation. Switching between the three modes of operation and aligning components are very simple, as this complete set of high quality components is carefully mounted on a heavy, stable base.
