Abstract

a. Système oculaire pour système optique infrarouge afocal non galiléen. b. Système oculaire caractérisé en ce qu'il comprend deux éléments de lentilles, l'élément arrière étant convergent et comportant une surface arrière, soit convexe, soit concave, et une surface avant convexe, et l'élément avant se présentant sous la forme d'une ménisque à surface arrière convexe et à surface avant concave, le rayon de courbure de la surface arrière concave étant plus grand que celui de la surface avant concave, mais l'épaisseur de l'élément avant étant telle qu'elle lui procure une convergence positive. c. L'invention s'applique aux systèmes oculaires pour système optique infrarouge afocal non galiléen.
