FIELD: physics.
SUBSTANCE: proposed device comprises opaque casing, dispersing element arranged there inside, and digital camera arranged there outside with light wavelength metre attached on camera shield. Camera lens is fitted in tube attached to casing inner wall, tube ID complying with lens OD, via casing front wall opening. Slot-like radiation channel is located on the left of said opening. Dispersing element represents a fragment of CD cut perpendicular to disc track direction and attached to casing opposite side, perpendicular to said tube with lens.
EFFECT: simplified design, fast registration of spectrum.
