Title (EN) OPTICAL DEVICE
(FR) DISPOSITIF OPTIQUE
(JA) 光学装置
Abstract:
(EN) The present invention provides an optical device having high transmittance in a wide wavelength band, and in which the incidence and emission optical axes do not change when the wavelength changes. For this purpose, an optical device according to the present invention includes a transmissive diffraction element (2) that diffracts incident light, a reflection element (3) that reflects the incident light, and a rotation mechanism (4) that supports the transmissive diffraction element (2) and the reflection element (3). The transmissive diffraction element (2) and the reflection element (3) are supported so as to be rotatable about one rotation shaft of the rotation mechanism (4). In this case, preferably provided is an optical device in which intersecting lines of a light-diffracting surface of the diffraction element (2) and a light-reflecting surface of the reflection element (3) are arranged so as to coincide with said rotation shaft.
(FR) La présente invention concerne un dispositif optique ayant une transmittance élevée dans une large bande de longueurs d'onde, et dans lequel les axes optiques d'incidence et d'émission ne changent pas lorsque la longueur d'onde change. À cet effet, un dispositif optique selon la présente invention comprend un élément de diffraction transmissif (2) qui diffracte la lumière incidente, un élément de réflexion (3) qui réfléchit la lumière incidente et un mécanisme de rotation (4) qui soutient l'élément de diffraction transmissif (2) et l'élément de réflexion (3). L'élément de diffraction transmissif (2) et l'élément de réflexion (3) sont soutenus de manière à pouvoir tourner autour d'un arbre de rotation du mécanisme de rotation (4). Dans ce cas, il est prévu de préférence un dispositif optique dans lequel des lignes d'intersection d'une surface de diffraction de lumière de l'élément de diffraction (2) et une surface réfléchissant la lumière de l'élément de réflexion (3) sont agencées de manière à coïncider avec ledit arbre de rotation.
(JA) 本発明は、広い波長帯域において高い透過率を有しつつ、波長変化に際し、入射・射出光軸が不変となる光学装置を提供する。 そのため本発明に係る光学装置は、入射した光を回折させる透過型回折素子(2)と、前記入射した光を反射させる反射素子(3)と、前記透過型回折素子(2)と前記反射素子(3)を支持する回転機構(4)と、を備え、前記透過型回折素子(2)と前記反射素子(3)は、前記回転機構(4)の1つの回転軸の回りに回転可能となるよう支持される。この場合において、前記回折素子(2)において光が回折する平面と、前記反射素子(3)において光が反射する平面との交線が、前記回転軸と一致して配置される光学配置を備えることが好ましい。
