Interferometer

Experiment topics • Michelson interferometer • Fabry-Perot interferometer • Determination of the refractive index of glass* • Determination of the refractive index of air* • Twyman-Green test for optical components (qualitative)* * U10351 Accessory set required This complete equipment set comprises high-grade optical components mounted on a heavy, rigid base plate for precise and reproducible measurements. The large optical components permit a generation of clear and well-defined interference patterns in daylight. The reflective observation screen has an adjustable inclination. Pre-defined component positions allow quick rearrangement to ensure 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 laser base plate.
