Abstract : A mirror objective lens dependent on certificate 139101 is described. In order to correct chromatic aberration and image curvature and also to diminish coma and astigmatism, a double-convex lens is placed close to the image surface of the objective. The first (according to the direction of light travel) radius of curvature of this lens is less than the second and its optical power is greater than the optical power of the objective by 1.3 orders of magnitude. A mirror lens of this description in which an aspherical correction is made on the spherical mirror, the divergence of the coordinates of the mirror from spherical being monotonic.
