This equipment combines the historically important Michelson interferometer, the high resolution Fabry-Perot interferometer, and the useful Twyman-Green interferometer in one unit. Michelson interferometer is still an important instrument in today’s physics laboratories and is used for observing two-beam interference phenomena. Fabry-Perot interferometer is for observing multiple-beam interference and measuring the fine structure of spectrum. Twyman-Green interferometer is used to measure the defects in optical components such as lenses, prisms, and windows etc.
Measurements are precise in three classical modes of operation. Switching between the three modes of operation and aligning components are very simple, as this complete set of high quality components is carefully mounted on a heavy, stable base.
Using this instrument, the following experiment examples can be conducted:
1.Two-beam Interference observation
2.Equal-inclination fringe observation
3.Equal-thickness fringe observation
4.White-light fringe observation
5.Wavelength measurement of the Sodium D-lines
6.Wavelength separation measurement of the Sodium D-lines
7.Measurement of the refractive index of air
8.Measurement of the refractive index of a transparent slice
9.Multi-beam interference observation
10.Measurement of the He-Ne laser wavelength
11.Interference fringe observation of the Sodium D-lines
12.Demonstrating the principle of a Twyman-Green interferometer
