Key Features:
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 the 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. This system, the Precision (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 (see "Related Products" below). |
