Michelson Interference Kit
Function introduction
Laser beam is split into transmission and reflection beams through the beam split prism. After reflected by a 0° incident mirror separately, the two beams are merged again via the beam split prism. Interference fringes can be generated on any planes through the combined laser path, and interference fringes characterizes the difference in wavefront and phase of the two beams. If two spherical laser beams interfere with each other, concentric annular light and dark stripe can be obtained. If two approximate plane laser beams interference, the straight light and dark stripes can be obtained.
Two interference arm directions are formed by inserting two sets of optical rods perpendicular to each other. In addition to its own two-dimensional pitch correction, the two mirrors can also slide backwards to change the length of the interference arm to meet the insertion of special application substances in the interference arm and change the wavefront and phase of one of the beams. One mirror is fixed to the precision translation stage for precise interference arm length changes.
Typical application
This system kit can be applied to the following aspects:
- Measurement of refractive index change of transparent materials
- Study on phase change of transparent materials
- Surface accuracy measurement researches
(If there are special requirements of light source or displacement control, please discuss the program and customize it with us.)
