Abstract

Abstract Translated from French Collimateur pour le contrôle cu le réglage de l'harmonisation entre deux dispositifs optiques fonctionnant chacun sur une gamme de longueurs d'ondes distincte de l'autre et comportant un trou source (1) pratiqué dans un miroir plan (5), éclairé par une source (2) rayonnant dans les deux gammes de longueurs d'ondes et placé au foyer d'un collimateur à miroirs. Le faisceau issu de ce collimateur à miroirs fournit après réflexion sur le miroir (12) un premier faisceau de lumière parallèle (6) transmettant l'une des gammes de longueurs d'ondes et, après transmission à travers la lame à faces sensiblement parallèles (4) et un diasporamètre (8), un second faisceau de lumière parallèle (7) transmettant l'autre gamme de longueurs d'ondes. Les faisceaux ayant le même entre axes que celui des deux dispositifs optiques sont rendus rigoureusement parallèles au moyen du diasporamètre (8). Collimator for control or adjustment of the harmonization between two optical devices each operating on a range of wavelengths distinct from the other and comprising a source hole (1) made in a plane mirror (5), illuminated by a source (2) radiating in the two wavelength ranges and placed at the focus of a mirror collimator. The beam coming from this collimator with mirrors provides after reflection on the mirror (12) a first parallel beam of light (6) transmitting one of the ranges of wavelengths and, after transmission through the blade with substantially parallel faces ( 4) and a diasporameter (8), a second parallel beam of light (7) transmitting the other range of wavelengths. The beams having the same between axes as that of the two optical devices are made rigorously parallel by means of the diasporameter (8).
