Introduction
This equipment integrates the historically important Michelson interferometer, the high resolution Fabry-Perot interferometer and the useful Twyman-Green interferometer into one unit. The Michelson interferometer is still an important instrument in today's laboratories. As the most typical instrument for interferometry, Michelson interferometer is often the first to be introduced to students. The Fabry-Perot interferometer is also an important metrological tool, allowing precise measurements of wavelength and free spectral range. A Twyman-Green interferometer is a very useful variant of the Michelson interferometer, usually used for measuring defects in optical components such as lenses, prisms, plane-parallel windows, laser rods, and plane mirrors. Measurements are precise in three modes of operation. Switching between the three modes and aligning components are relatively simple.
Example patterns of equal inclination fringes and equal thickness fringes produced by this interferometer.
Key features
- Stable: heavy steel base enhances stability.
- Three Modes: Michelson, F-P & Twyman-Green.
- Easy Operation: Two micrometers, one for presetting, the other for fine adjustment to control mirror movement. Mounting holes for screen, air chamber, easy to assemble or dismantle.
- Precise: Min division of micrometer 0.2 mm. Flatness of BS & compensator 0.05 ..
- Large Optics: 30mm in diameter produces larger patterns for more accurate experiment result.
- Complete Solution: Includes necessary components to perform 9 experiments in Michelson mode, 2 in Fabry-Perot mode and 1 in Twyman-Green mode.
- Time saving Documentation: Comprehensive document contains both theoretical and practical description, save your time for preparing the experiments.
- Competitive Price: affordable price within your budget.
