Title (EN) OPTICAL LENS
(FR) LENTILLE OPTIQUE
(JA) 光学レンズ
Abstract: front page image
(EN)The purpose of the present invention is to provide an optical lens that exhibits a low water absorptivity and an excellent heat resistance, excellent transparency, and excellent optical properties (refractive index, Abbe number, photoelastic coefficient). The optical lens comprises a polyester resin that contains a unit (A) represented by general formula (1).
(FR)Le but de la présente invention est de fournir une lentille optique qui présente une faible absorptivité de l'eau et une excellente résistance à la chaleur, une excellente transparence, et d'excellentes propriétés optiques (indice de réfraction, nombre d'Abbe, coefficient photoélastique). La lentille optique comprend une résine de polyester qui contient une unité (A) représentée par la formule générale (1).
(JA)低吸水性であり、耐熱性、透明性及び光学特性(屈折率、アッベ数、光弾性係数)に優れる光学レンズの提供を目的とする。下記一般式(1)で表される単位(A)を含むポリエステル樹脂からなる光学レンズ。
