CA 2667803

A lens assembly (4) having a first lens (12) and a second lens (13) each having a spherical surface section (12b, 13b) at its one end surface, a band-pass filter (14), and a sleeve (15) for receiving the band-pass filter (14). In the lens assembly (4), the first lens (12) is fixed to one end side of the sleeve (15) with the spherical surface section (12b) made to be in contact with an opening edge on the one end side of the sleeve (15), and the second lens (13) is fixed to the other end side of the sleeve (15) with the spherical surface section (13b) is made to be in contact with an opening edge on the other side of the sleeve (15). An optical device (1) is constructed by assembling the lens assembly (4) in it.

L'agencement de lentilles (4) selon l'invention comporte une première lentille (12) et une seconde lentille (13), chacune ayant une section de surface sphérique (12b, 13b) au niveau de sa seule surface d'extrémité, un filtre passe-bande (14), et une gaine (15) destinée à recevoir le filtre passe-bande (14). Dans l'agencement de lentilles (4), la première lentille (12) est fixée à une extrémité de la gaine (15), la section de surface sphérique (12b) étant conçue pour être en contact avec une arête d'ouverture sur un côté d'extrémité de la gaine (15), et la seconde lentille (13) est fixée à l'autre côté d'extrémité de la gaine, la section de surface sphérique (13b) étant conçue pour être en contact avec une arête d'ouverture sur l'autre côté de la gaine (15). Le dispositif optique (1) selon l'invention est construit en montant l'agencement de lentilles (4) en lui.
