'A useful Optical grating to correct Optical Aberrations.

摘要

Optical grating used to correct Optical Aberrations.It consists of a First Plurality of bars (2) triangular in cross section, which are arranged in parallel with each other; and a Second Plurality of bars (3) also triangular in cross section, which are arranged parallel to each other; but in a relationship perpendic With regard to the first level bars (2) so that the two sets of bars (2)3) forming a Grid that delimits Square apertures (4) to allow the passage of Light. Application in the correction of optical Aberrations, both in natural lenses such as the eye, as in Photographic lenses and the like.
