FIELD: optics. SUBSTANCE: the optical valve has a ring magnet system with an axial magnetization and a polarizer, magnetooptical rotator and an analyzer successively located on the optical axis. Besides, it has a compensator, the of the magnetooptical rotator is made in the form of a taper boss, and the generating line of the taper boss of the magnetooptical rotator is determined from known relationship L = 45°/(lambdaVn(Ar+B) and r lies within 0<=r<=rmax, where rmax the radius of the magnetooptical rotator, r- the radial coordinate, the compensator end is made in the form of a taper recess, whose outer surface closely adjoins the outer surface of the taper boss of the end of the magnetooptical rotator, n = n', where n' - the refractive index of the compensator material. EFFECT: enhanced consumers' properties due to an enhanced quality factor of the optical valve. 2 dwg |
