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. The Precision (Basic) Interferometer (OS-9255A) 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. Features: Stable -- The massive (5 kg) base is machined from a single block of aluminum ensuring extremely stable optics. Smooth Mirror Movement -- With the taut-band suspension system, there's no starting or stopping friction and virtually no backlash (less than 0.5 micron). Precise Measurements -- Mirror control is extremely fine -- one micron per division of the micrometer head. The mirrors and beam-splitter are flat to 1/4 wavelength to ensure uniform interference patterns. Larger Optics -- The 3.2 cm (1-1/4") diameter optics in the PASCO Interferometer produce larger and sharper interference patterns for better experimental results. Complete -- Includes everything necessary to perform basic Michelson and Fabry-Perot interferometry. With this Complete Interferometer System, students can also: Demonstrate that cross-polarized beams will not interfere Measure lens irregularities in Twyman-Green Mode Measure the indices of refraction for air and glass. The indices of refraction for user-supplied materials can also be measured.
