Abstract: front page image
(EN)An optical element (10) which comprises as shown in the figure an input optical member (11) molded to a unitary body by arranging a plurality of optical fibers (14) in parallel with each other, and having incident and emergent surfaces (11a, 11b) which make angles of 31° and 90° respectively to an optical axis, and an output optical member (12) also molded to a unitary body by arranging a plurality of optical fibers (14) in parallel with each other, and having incident and emergent surfaces (12a, 12b) which make angles of 31° and 90° respectively to an optical axis, wherein the emergent surface (11b) of the input optical member (11) and the incident surface (12a) of the output optical member (12) are fixed to each other in a contacting state, the emergent surface (11b) of the input optical member (11) is polished optically to a specular surface and the incident surface (12a) as a whole of the output optical member (12) is polished coarsely so as to provide a center line average coarseness of 0.49 $g(m)m.
(FR)L'invention porte sur un dispositif optique (10) comportant: un élément optique d'entrée (11) coulé sur un corps monolithique consistant en plusieurs fibres optiques (14) en parallèle présentant des surfaces incidente et émergente (11a, 11b) faisant des angles respectifs de 31° et de 91° avec un axe optique, ainsi qu'un élément optique de sortie (12) également coulé sur un corps monolithique consistant en plusieurs fibres optiques (14) parallèles et présentant des surfaces incidente et émergentes (12a, 12b) faisant des angles respectifs de 31° et de 91° avec un axe optique. La surface émergente (11b) de l'élément optique (11) d'entrée, et la surface incidente (12a) de l'élément optique (12) de sortie sont reliées l'une à l'autre et en contact, la surface émergente (11b) de l'élément optique (11) d'entrée est d'un poli optique spéculaire, tandis que la totalité de la surface incidente (12a) de l'élément optique (12) de sortie est d'un poli rugueux correspondant à une rugosité moyenne de ligne centrale de 0,49 $g(m)m.
