Title (EN) FRESNEL LENS AND OPTICAL DEVICE PROVIDED WITH SAME
(FR) LENTILLE DE FRESNEL ET DISPOSITIF OPTIQUE EN ÉTANT ÉQUIPÉ
(JA) フレネルレンズ、及びそれを備えた光学装置
Abstract:
(EN)  Provided is a Fresnel lens having excellent heat resistance and being capable of producing a change to even, high-quality light and dispersing the light without reducing the center illuminance thereof even when a poor-quality semiconductor light source is used. This Fresnel lens has two or more chevron-shaped prisms on a surface thereof, the Fresnel lens comprising a cured material of a curable composition containing an epoxy compound (A), and a roughening treatment being performed on the prism surface of the chevron shape in which the longest inclined side is formed in a cross-section obtained by cutting the Fresnel lens in a plane which is perpendicular to a reference face of the Fresnel lens and passes through the center of the Fresnel lens.
(FR)  La présente invention concerne une lentille de Fresnel douée d'une excellente résistance à la chaleur et pouvant modifier une lumière uniforme de haute qualité et disperser la lumière sans réduire son éclairement central même lorsqu'une source de lumière à semi-conducteurs de mauvaise qualité est utilisée. Ladite lentille de Fresnel comprend deux prismes ou plus en forme de chevron sur une de ses surfaces, la lentille de Fresnel comprenant un matériau durci d'une composition durcissable contenant un composé époxy (A) et un traitement de rugosification étant réalisé sur la surface de prisme en forme de chevron dans lequel le côté incliné la plus long est formé dans une section transversale obtenue par découpe de la lentille de Fresnel dans un plan qui est perpendiculaire à une face de référence de la lentille de Fresnel et traverse le centre de la lentille de Fresnel.
(JA)  耐熱性に優れ、品質が悪い半導体光源を使用した場合であっても、中心照度を低下させることなく、むらのない高品質な光に変えて拡散することができるフレネルレンズを提供する。 本発明のフレネルレンズは、表面に山形形状のプリズムを2個以上有するフレネルレンズであって、エポキシ化合物(A)を含有する硬化性組成物の硬化物からなり、前記フレネルレンズの中心点を通り、且つ前記フレネルレンズの基準面に垂直な面で前記フレネルレンズを切断した際の断面において最も長い傾斜辺を形成する山形形状のプリズム表面に粗化処理が施されてなる。
