Dichroic Filter

 Dichroic Filters (Color Separation Filters) separate visible light (400 nm - 700 nm) into usable spectral regions, reflecting one region while transmitting the other. Dichroic Filters are used in systems where it is desired to split the incident energy into two or more beams, each having a different spectral content of color.
