Title (EN) BEAM HOMOGENIZER COMPRISING ZOOMING MECHANISM
(FR) HOMOGÉNÉISATEUR DE FAISCEAU COMPORTANT UN MÉCANISME DE VARIATION DE FOCALE
(KO) 주밍기구가 포함된 빔 균질기
Abstract:
(EN) The present invention relates to a beam homogenizer comprising a zooming mechanism, and the present invention comprises: a first array lens which is fixedly disposed on an optical axis along which a laser is output and on which microlenses with a predetermined shape are arranged at regular intervals on a plate-shaped base; a second array lens which is spaced apart from the first array lens, disposed on the same optical axis, and movably disposed along the optical axis, and on which microlenses with a predetermined shape are arranged at regular intervals on the plate-shaped base; a third array lens which is spaced apart from the second array lens, disposed on the same optical axis, and movably disposed along the optical axis, and on which microlenses with a predetermined shape are arranged at regular intervals on the plate-shaped base; and a condensing lens which is spaced apart from the third array lens, is fixedly disposed on the same optical axis, and condenses the received laser light.
(FR) La présente invention concerne un homogénéisateur de faisceau comprenant un mécanisme de variation de focale, la présente invention comprenant : une première lentille matricielle disposée à demeure sur un axe optique le long duquel un laser est émis et sur laquelle des microlentilles d'une forme prédéterminée sont agencées à intervalles réguliers sur une base en forme de plaque ; une deuxième lentille matricielle espacée de la première lentille matricielle, qui est disposée sur le même axe optique et disposée mobile le long de ce dernier, sur laquelle des microlentilles d'une forme prédéterminée sont agencées à intervalles réguliers sur la base en forme de plaque ; une troisième lentille matricielle espacée de la deuxième lentille matricielle, qui est disposée sur le même axe optique et disposée mobile le long de ce dernier, sur laquelle des microlentilles d'une forme prédéterminée sont agencées à intervalles réguliers sur la base en forme de plaque ; et une lentille de condensation espacée de la troisième lentille matricielle, qui est disposée à demeure sur le même axe optique et qui condense la lumière laser reçue.
