Title (EN) AUTO-FOCUS MICRO-LENS HOLDER
(FR) SUPPORT DE MICROLENTILLES AUTOFOCUS
Abstract:
(EN) A microlens holder for supporting at least one microlens in alignment with a light source is described. Each of the microlenses has a radius and a back focal length varying linearly with the radius. The microlens holder includes a base having at least one V-groove therein for receiving the at least one microlens, each of the V-grooves having a pair of side walls, both side walls being tilted by an angle $g(u) relative to the plane of the emitting light source. The value is defined by the relationship cos($g(u)) = (1 + k)-1, where k is a positive constant factor associated with the at least one microlens. The microlens holder allows auto-focussing of the light source, independently of the exact diameter of the microlenses mounted in the holder. The optical alignment of the microlenses is made easier as well.
(FR) L'invention porte sur un support d'au moins une microlentille la maintenant en alignement avec au moins une source lumineuse. Chacune des microlentille présente un rayon, et une distance focale arrière variant linéairement avec le rayon. Ledit support comprend une base présentant au moins une rainure en V destinée à recevoir au moins une microlentille, les parois latérales desdites rainures faisant chacune un angle $g(u) par rapport au plan de la source émettrice de lumière, dont la valeur est définie par la relation cos ($g(u)) = (1 + k)-1, où k est un facteur constant positif associé à au moins une microlentille. Le susdit support permet donc une autofocalisation de la source lumineuse indépendamment de la précision du diamètre des microlentilles y étant placées. L'alignement optique des microlentilles s'en trouve également facilité.
