Product Details
Precision Interferometer
A high-precision, movable-mirror interferometer that can be used to perform Michelson, Fabry-Perot & Twyman-Green interferometry.
Description
No study of interferometry should overlook the historical importance of the Michelson interferometer. Yet in the laboratory, the Fabry-Perot and Twyman-Green interferometers can be more important tools; the first for high-resolution spectroscopy, the second for testing and producing optical components with aberrations that can be measured in fractions of a wavelength.
The PASCO Interferometer is a high-precision, movable-mirror interferometer that can be used to perform Michelson, Fabry-Perot and Twyman-Green interferometry. Mirrors are attached with thumbscrews, so it’s easy to set up and change configurations.
The PASCO Interferometer can be ordered in a variety of systems. The OS-9255A Basic Interferometer can be operated in either the Michelson or Fabry-Perot modes. The Complete Interferometer Systems also contain components for the Twyman-Green mode and a vacuum pump for the refractive index of air experiment.
Note: The fitted case will hold all components and accessories except the 5 kg base, which must be stored separately.
