Title (EN) MULTI-FOCAL OPTICAL LENS, AND MANUFACTURING METHOD FOR SAME
(FR) LENTILLE OPTIQUE MULTIFOCALE ET SON PROCÉDÉ DE FABRICATION
(JA) 多焦点眼用レンズとその製造方法
Abstract:
(EN)  In order to reduce halos that occur in multi-focal optical lenses, the mechanism of the phenomenon was elucidated and a solution was found based on the results. Thus provided are a multi-focal optical lens having a new structure and a manufacturing method for the same which can effectively reduce halos. A multi-focal optical lens having a focal point formation region (28), which forms at least two focal points, provided to an optical portion (12) of a lens (10), wherein a cancellation region (30) is provided to the optical portion (12), said cancellation region (30) providing diffracted light of an amplitude distribution that reduces, on the image plane of the first focal point among the aforementioned focal points, the amplitude distribution of light other than the light that forms the first focal point.
(FR) Afin de réduire les halos qui apparaissent dans des lentilles optiques multifocales, le mécanisme du phénomène a été élucidé et une solution a été trouvée sur la base des résultats. La présente invention concerne donc une lentille optique multifocale ayant une structure innovante qui, avec son procédé de fabrication, permet de réduire efficacement les halos. Dans une lentille optique multifocale d'après la présente invention, une région de formation de points focaux (28) forme au moins deux points focaux et elle est ménagée sur une partie optique (12) d'une lentille (10), et une région de suppression (30) est ménagée sur la partie optique (12). Ladite région de suppression (30) émet une lumière diffractée d'une distribution d'amplitude qui réduit, sur le plan image du premier point focal parmi les points focaux susmentionnés, la distribution d'amplitude de toute lumière autre que la lumière qui forme le premier point focal.
(JA)  多焦点眼用レンズにおいて生成されるハロの低減を目的としてその機構の解明を行い、その結果に基づく解決方法から見出された、ハロを効果的に低減することのできる、新規な構造の多焦点眼用レンズおよびその製造方法を提供する。 レンズ10の光学部12に対して、少なくとも二つの焦点を与える焦点形成用領域28が設けられた多焦点眼用レンズにおいて、前記焦点のうち第一の焦点における像面上で、第一の焦点を形成する光以外の光による振幅分布を減少せしめる振幅分布の回折光を与えるキャンセル用領域30を、光学部12に設けた。
