China Wholesale velocity of light Factories – LIT-4 Michelson Interferometer – Labor
China Wholesale velocity of light Factories – LIT-4 Michelson Interferometer – Labor Detail:
Description
The Michelson interferometer is a fundamental instrument in physics laboratories. The platform design is used to facilitate the addition of the studied material to the optical path. It can observe equal inclination interference, equal thickness interference and white light interference, measure monochromatic light wavelength, sodium yellow double line wavelength difference, transparent dielectric slice and air refractive index.
This equipment contains a Michelson interferometer on one square base, which is made of a thick steel plate with a rigid-frame. He-Ne laser as light source, it can also be changed to semiconductor laser.
The Michelson interferometer is known for observing two-beam interference phenomena such as equal-inclination interference, equal-thickness interference, and white-light interference. It has been used for precise measurements of wavelengths, small-path distances, and refractive indices of transparent media.
Experiment Examples
1. Interference fringe observation
2. Equal-inclination fringe observation
3. Equal-thickness fringe observation
4. White-light fringe observation
5. Wavelength measurement of Sodium D-lines
