interferometer

The Interferometer is made up of a complete equipment set comprising high-grade optical components mounted on a heavy, rigid base plate, for precise and reproducible measurements. The large optical components permit a the generation of clear and well-defined interference patterns in daylight. The reflective observation screen has an adjustable inclination, while pre-defined component positions allow quick rearrangement to ensure extremely rapid preparation for the various experiments.

uses of the interferometer

The interferometer is suitable for a range of experiment topics, including:

• Michelson's interferometer
• Fabry-Perot interferometer
