definition
| - An optical filter is an optical subsystem that selectively transmits light having certain properties (often, a particular range of wavelengths, that is, range of colours of light), while blocking the remainder. They are commonly used in photography, in many optical instruments, and to colour stage lighting Optical filters can be arranged to segregate and collect light by wave length.
