Abstract

a. Système optique grossissant. b. Système optique caractérisé en ce que le dispositif plan comporte, sur deux de ses surfaces parallèles, des rangées respectives de rainures telles que la section droite de chaque surface transversalement à la longueur d'une rainure se présente sous la forme d'une pluralité d'arcs, les rainures sur l'une des surfaces étant disposées transversalement par rapport aux rainures sur l'autre surface. c. L'invention s'applique aux systèmes optiques grossissants.at. Magnifying optical system. b. Optical system characterized in that the planar device comprises, on two of its parallel surfaces, respective rows of grooves such that the cross section of each surface transversely to the length of a groove is in the form of a plurality of arcs, the grooves on one surface being disposed transversely to the grooves on the other surface. vs. The invention applies to magnifying optical systems.
