Precision Interferometer
• Modes: Michelson, Fabry-Perot and Twyman-Green
• Large Precision Optics
• 5 kg Machined Aluminum Base

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 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, including 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 0 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 beamsplitter are flat to a º wavelength to ensure uniform interference patterns.
• Larger Optics – The 3.2 cm (1-1/4”) diameter optics in the interferometer produce larger and sharper interference patterns for better experimental results.
