Description

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.
