Title
(EN) OPTICAL ELEMENT FOR UNIFORM ILLUMINATION AND OPTICAL SYSTEM INCORPORATING SAME
(FR) ELEMENT OPTIQUE POUR UN ECLAIRAGE UNIFORME ET SYSTEME OPTIQUE INTEGRANT CET ELEMENT
Abstract
(EN)
An optical element for homogenizing lignt and an optical system incorporating same are disclosed. The optical element includes an optical rod that has an input face and an output face. The input face of the optical element is not parallel to the output face of the optical element.
(FR)
L'invention concerne un élément optique pour homogénéiser de la lumière, et un système optique intégrant cet élément optique. L'élément optique de l'invention comprend une tige optique présentant une face d'entrée et une face de sortie. La face d'entrée de l'élément optique n'est pas parallèle à la face de sortie de l'élément optique.
