Thin film for Prism

Thin film is a technique where the thickness can be from nm to um.

As the dichroic mirror is a mirror that reflects or transmits specific wavelengths using interference of light by a thin film. As a technique, several tens of layers of dielectric materials with different index are mainly used, and light interference generated by the difference in optical path length is used to obtain a specific wavelength.
