FIELD: physics.
SUBSTANCE: anti-laser protective light filter has a radiation-absorbing component made from coloured optical glass and a reflecting multi-layer dielectric coating on said glass. According to the invention, the wavelength of the maximum of the spectral reflection coefficient of the dielectric coating is shifted towards the long-wave region of the spectrum with respect to the wavelength of the active laser radiation by a value d=0.2-0.3 times the half-width of the spectral reflection band of the dielectric coating.
EFFECT: high degree of protection with increase in angle of incidence of laser radiation.
