Complete both Michelson interferometer and Fabry-Perot interferometer experiments with this high-grade equipment set. With the optional accessory kit, students can also determine the refractive index of glass, refractive index of air, and Twyman-Green qualitative test for optical components. This complete equipment set of optical components is 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 also features an adjustable inclination. Pre-defined component positions allow for 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. Beam splitter: Evenness: λ/10 (front side), λ/4 (rear side) Size: 40 mm dia. Surface-coated mirror: Evenness: <λ/2. Size: 40 x 40 mm2. Eccentric reduction: approx. 1:1000 (individual calibration specified on eccentric base) Size: 24.5 x 33 x 2.5cm; weight: 10 lbs. A He-Ne Laser and the Accessory Kit, both available separately are required to complete some of the experiments.
Interferometer Accessory Kit This accessory set for the interferometer consists of a vacuum cell for determining the refractive index of air and a glass plate on a rotatable holder for examining the surface quality of optical components or Twyman-Green interferometer. A vacuum hand pump and silicone tube are also required.
