Method for correcting optical wavefront aberrations, and optical system, for example a telescope, thus obtained

摘要

The optical wavefront for various wavelengths between the entrance eyepiece side (EP) and objective side (AP), in visual field is calculated. A compensation plate (7) is placed between the reflectors (4,5) for adjusting the phase difference using calculated optical wavefront. Independent claims are also included for the following: (a) optical system manufacturing method; (b) telescope.
