Title
(EN) OPTICAL ELEMENT AND PRODUCTION METHOD THEREFOR
(FR) ÉLÉMENT OPTIQUE ET SON PROCÉDÉ DE PRODUCTION
(JA) 光学素子およびその製造方法
Abstract
(EN)
Provided is a method for producing an optical element by press molding a prismatic material so as to shape the light-transmitting section of the optical element and a flange extending outward from the light transmitting section. In this production method, with respect to the end face of the flange, only the corner portions of the material are subjected to the mold transfer.
(FR)
L'invention concerne un procédé de production d'un élément optique par moulage par compression d'un matériau prismatique de façon à former la section de transmission de lumière de l'élément optique et une bride s'étendant vers l'extérieur à partir de la section de transmission de lumière. Dans ce procédé de fabrication, par rapport à la face d'extrémité de la bride, seules les parties de coin du matériau sont soumises au transfert de moule.
(JA)
角柱形状の素材から光学素子の光透過部、および光透過部から外側に延在するフランジをモールドプレス成形することを通じて光学素子を製造する方法が提供される。かかる製造方法では、フランジの端面に対して、素材の角部のみを金型転写に付す。
