Abstract
(EN)
An optical system is provided with a prism (15) having an incidence surface (15a), an exit surface (15d), and a first reflective surface (15b). The interior of the prism (15) includes an intermediate image formation position (Px) of a component (Rx) of laser light (R) in an X direction, and the intermediate image formation position (Px) differs from an intermediate image formation position (Py) of a component of laser light (Ry) in a Y direction orthogonal to the X direction.

Système optique pourvu d'un prisme (15) ayant une surface d'incidence (15a), une surface de sortie (15d) et une première surface réfléchissante (15b). L'intérieur du prisme (15) comprend une position de formation d'image intermédiaire (Px) d'un composant (Rx) de lumière laser (R) dans une direction X et la position de formation d'image intermédiaire (Px) diffère d'une position de formation d'image intermédiaire (Py) d'un composant de lumière laser (Ry) dans une direction Y orthogonale à la direction X.
