FIELD: technological processes.
SUBSTANCE: narrow-band filter consists of two identical transparent triangular prisms, which are made of a material with a high refractive index. Between them are alternating layers made of materials with low and high refractive indices.
EFFECT: simplification of the design of the interference filter and expansion of the transmission suppression zone.
