Description
表1は本発明の実施例(No.1〜11)、表2は比較例(No.12〜16)を示す。
得られた試料について、屈折率(nd)、アッベ数(νd)、ガラス転移点(Tg)、耐候性、耐水性、透過率を以下の方法により測定または評価した。結果を表1および表2に示す。また、No.4およびNo.15の試料の耐候性試験後の写真を図1に、No.4およびNo.13の溶融ガラス成形後の写真を図2に、No.2、No.4およびNo.11の各試料の透過率曲線を図3〜5にそれぞれ示す。
実施例であるNo.1〜11の試料は所望の光学特性を有しつつ、耐候性および耐水性に優れていた。一方、比較例であるNo.12、15、16の試料は耐候性および耐水性に劣っていた。また、No.15の試料は、波長300〜500nmの範囲において、λ70−λ5が100nmより大きく、紫外域の吸収特性に劣っていた。No.13、14の試料はガラス化しなかった。
