Dichroic mirror

A dichroic mirror is a multilayer optical thin-film mirror that utilizes light interference to separate light from a source into transmitted and reflected light.
It can extract specific wavelengths from a broad light source or combine two light beams of different wavelengths.

Features

Thin dielectric films with different refractive indices are coated in multiple layers, and light interference is used to allow the selection of transmission or reflection of light from a light source at the desired wavelengths.

The number of layers of thin dielectric film coated can be from a few to several hundred, which allows various characteristics to be realized.
The shape of the substrate to be coated can be anything from flat to a parabolic mirror.
