A holographic corrector is considered for eliminating surface aberrations of the main telescope mirror, specifically a compound mirror, on the basis of the existing relation between spectral range, wavefront distortion, and chromatic aberration. This relation is examined for typical holographic conversion of a plane wavefront into a spherical one. A hologram recorded with counter light beams yields a spectral band which widens with decreasing thickness of the light-sensitive film and makes it possible to eliminate any path-difference resulting from wavefront conversion. This requires making the curvature of the photographic plate equal to half the sum of the curvature of the original reference wavefronts. Such a correcting hologram must be placed in the plane of the exit pupil of the objective.
