Mach-zender study

Item Code: SN1057

Working and Principle :

The Mach-Zender interferometer consists of two semi-reflecting plates (beamsplitters) and mirrors. A light beam is divided into two, after which both beams are recombined by eans of a semi-reflecting mirror. One of these beams will be named the Reference beam, while the other will allow us to take measurements on the vacuum index or plate thickness.
