Double prism interference experiment
Experiment contents and related subjects:
Adjust the optical path to observe the sub-wave front interference fringes and experience the principle and theory of sub-wave front interference.
Measure the interference fringe space and project the laser wavelength.
Features of instruments:
Using semiconductor laser (650nm, 4mW) as the light source and it’s power stability is better than 1%.
Use a one-dimensional displacement rack + 12 steps light probe to measure data, it’s more objective and the precision can reach 0.02mm.
The optical experiment guide is 1200mm.
Complete set of equipment:
Optical experiment guide, semiconductor laser, biprism, lens, laser power indicator, one-dimensional displacement rack+ 12 steps light probe and etc..
