Abstract:
(EN) An optical device 30 includes a GRIN lens 35, a front optical fiber 31 for causing light to enter the GRIN lens 35, and a rear optical fiber 32 whereinto the light exiting from the GRIN lens 35 enters. A method for adjusting the beam quality includes a measurement step P2 for measuring the beam quality of light entering into the front optical fiber 31 and exiting from the rear optical fiber 32 through the GRIN lens 35, and an adjustment step P3 for adjusting the length of the GRIN lens 35 on the basis of the results of the measurement step P2.
(FR) L'invention concerne un dispositif optique 30 qui comprend une microlentille focalisante 35, une fibre optique avant 31, pour amener la lumière à entrer dans la microlentille focalisante 35, et une fibre optique arrière 32 dans laquelle entre la lumière sortant de la microlentille focalisante 35. Un procédé pour ajuster la qualité de faisceau comprend une étape de mesure P2 pour mesurer la qualité de faisceau de lumière entrant dans la fibre optique avant 31 et sortant de la fibre optique arrière 32, par l'intermédiaire de la microlentille focalisante 35, et une étape d'ajustement P3 pour ajuster la longueur de la microlentille focalisante 35 sur la base des résultats de l'étape de mesure P2.
(JA) 光デバイス30は、GRINレンズ35と、GRINレンズ35に光を入射する前段光ファイバ31と、GRINレンズ35から出射する光が入射する後段光ファイバ32と、を有する。ビーム品質の調整する方法において、前段光ファイバ31に光を入射し、GRINレンズ35を介して後段光ファイバ32から出射する光のビーム品質を測定する測定工程P2と、測定工程P2の結果に基づいて、GRINレンズ35の長さを調整する調整工程P3と、を備える。
