The invention concerns a system for achieving an optical image of an object (136), and/or for achieving optical collimation (137) of light from a light source (130), comprising a concave mirror (131; 134), the surface normal of which forms an angle with the incident light in a beam. A negative lens (132; 133) that co-operates with the concave mirror is arranged in the incident and/or exit beam paths such that an image with eliminated or reduced imaging aberrations is achieved in a focal plane (135), and/or that the exit light from a light source (130) is collimated (137).
L'invention concerne un système permettant de produire une image optique d'un objet (136) et/ou une collimation optique (137) de la lumière émise par une source lumineuse (130). Ce système comprend un miroir concave (131 ; 134) dont la surface normale forme un angle avec la lumière incidente d'un faisceau. Une lentille négative (132 ; 133) qui coopère avec le miroir concave, est placée dans le trajet de faisceau incident et/ou sortant de telle façon qu'une image avec suppression ou réduction des aberrations soit produite dans un plan focal (135) et/ou que la lumière sortante de la source lumineuse (130) soit collimatée (137).
