A beam splitter is an optical component that is used for splitting an incident light beam in two directions. Beam splitters are used to separate the light by a ratio of power between what is being transmitted through the optic and what is being reflected. Beam Splitters can also be used to separate polarization states as well as different wavelengths of light.
