Description

Experiment content:
Observe the interference phenomenon of light (equal thickness fringes, equal inclination fringes, white light color fringes)
Measure the wavelength of monochromatic light (optional laser and other monochromatic light source). Measure the wavelength difference of sodium yellow light and sodium yellow light double line (optional low pressure sodium lamp light source)
Measure the coherence length of sodium light (optional low-pressure sodium light source).
Observe white light interference fringes (optional parallel white light source).
Instrument features:
A precision two-dimensional adjustment frame is used to adjust the optical path.
Select different accessories to carry out a variety of experiments.
Complete set of equipment:
Michelson interferometer, light source (optional).
Main technical indicators:
The stroke of the moving mirror is 100mm/200mm.
The inching handwheel indexing value is 0.0001mm.
Wavelength measurement accuracy: when the fringe count is 100, the relative error of determining the wavelength of monochromatic light is less than 2%.
The flatness of the splitting plate and the compensation plate is λ/30.
The flatness of the moving mirror and the reference mirror is λ/20.
