mach-zehnder interferometer

The Mach-Zehnder Interferometer comprises a complete equipment set consisting of two beam splitters, two surface-coated mirrors, two observation screens and four polarisation filters. The optical components are all of the highest quality, and have been mounted on a heavy, rigid base plate for precise and reproducible measurements. Beyond the first beam splitter, the two parts of the split beam take different paths to the second beam splitter, where they are once again superimposed. This means that by adding in polarisation filters, it is possible for the two beams to be differently polarised. 

The large optical components permit a generation of clear and well-defined interference patterns , which can even be viewed in daylight as the tilt of the two reflecting observation screens is adjustable. Pre-defined component positions allow quick rearrangement, ensuring extremely rapid preparation for the various experiments. The equipment set includes a stable plastic box for storing the mounted and adjusted interferometer as well as the base plate for laser.
