Abstract

Optic grille used to correct optical aberrations. Consists of a first plurality of bars (2) of triangular transversal section, which are parallelly available between themselves; and of a second plurality of bars (3) also of triangular transversal section, which are also available parallelly between themselves; but in a perpendicular relationship with respect to the first bars (2), so that the two series of bars (2, 3) form a grid that delimates square-size openings (4), in order to permit the passage of the light. Of application in the correction of optical aberrations, both in natural lenses such as the eye, and in photographic and similar lenses. (Machine-translation by Google Translate, not legally binding)
