PG15-J Laser Plane InterferometerDetailed product description：

Product Introduction of PG15-J Laser Plane Interferometer:

1. The operation of PG15-J laser plane interferometer is based on the principle of double beam equal thickness interference.
2. According to the research results of modern optics, light has both wave and particle characteristics. The interference phenomenon of light is a characteristic of the wave nature of light.
