要約
(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.

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.
