Description
Известные устройства дл измерени абсолютных коэффициентов зеркального отражени с использованием системы из трех св занных между собой плоских зеркал, предназначенных дл вращени светового Пучка И установленных до измер емого зеркала, не дают возможности вращать щирокие или расход щиес световые пучки.The known devices for measuring absolute mirror reflection coefficients using a system of three interconnected flat mirrors designed to rotate the light beam AND installed before the measured mirror do not allow the wide or diverging light beams to rotate.
В предложенном изобретении дл избежани указанного недостатка в системе из трех зеркал использованы два плоских и одно вогнутое зеркало.In the proposed invention, in order to avoid this deficiency in the system of three mirrors, two flat and one concave mirror were used.
На чертеже показана оптическа схема устройства, имеюща три зеркала 1, 2-vi 3, из которых зеркало 5-вогнутое (сферическое, эллиптическое , параболическое), а зеркала 1 и 2 - плоские. Все три зеркала жестко св заны между собой и вращаютс как одна система вокруг оси О-О, при этом выход щий из системы пучок света вращаетс с удвоенной угловой скоростью.The drawing shows an optical diagram of the device, having three mirrors 1, 2-vi 3, of which the mirror is 5-concave (spherical, elliptical, parabolic), and mirrors 1 and 2 are flat. All three mirrors are rigidly connected to each other and rotate as one system around the O-O axis, while the light beam leaving the system rotates at twice the angular velocity.
Устройство может работать -в пучках с большой аппаратурой, не требу дополнительной фокусирующей оптики.The device can work in beams with large equipment, without the need for additional focusing optics.
