Description
рующего зеркала, во сколько :раз фокусное рассто ние объектива больше радиуса кривизны поверхности изображени .of the mirror, how much: once the focal length of the lens is greater than the radius of curvature of the image surface.
Следовательно, при одних и тех же погрешност х сканирующего механизма точность сканировани значительно увеличиваетс , что позвол ет более грубым механизмом получить высокую точность сканировани .Therefore, with the same errors of the scanning mechanism, the scanning accuracy is significantly increased, which allows a more coarse mechanism to obtain high scanning accuracy.
Предмет изобретени Зеркальиый объектив, содержащий первичное и вторичное вогнутые зеркала и третье выпуклое зеркало с центральным отверстием , отличающийс тем, что, с целью устранени перефокусировки, упрощени конструкции и повышени точности сканировани , он снабжен расположенным между вторичным и выпуклым зеркалами плоским зеркалом, установленным с возможностью поворота вокруг ортогональных осей, перпендикул рных к оптической оси объектива и проход щих через центр кривизны поверхности изображени .Object of the Invention A mirrored lens containing primary and secondary concave mirrors and a third convex mirror with a central hole, characterized in that, in order to eliminate refocusing, simplify the design and improve scanning accuracy, it is provided with a flat mirror arranged between the secondary and convex mirrors that is installed rotation about orthogonal axes perpendicular to the optical axis of the lens and passing through the center of curvature of the image surface.
