Description
1.無機光学素子
2.無機光学素子の製造方法
3.実施例
本発明を適用した無機光学素子は、柱状構造からなる複屈折膜と、複屈折膜上に形成された保護膜とを備え、複屈折膜が、柱状構造の間隙に保護膜の成分が侵入してなるものである。これにより、複屈折膜と保護膜成分とが結合し、複屈折膜と保護膜との高い密着性を得ることができる。
次に、本発明を適用した無機光学素子の製造方法について説明する。本発明を適用した無機光学素子の製造方法は、柱状構造からなる複屈折膜上に、保護膜を成膜し、柱状構造の間隙に保護膜の成分を侵入させるものである。これにより、複屈折膜と保護膜成分とを結合させ、複屈折膜と保護膜との密着性を向上させることができる。
以下、本発明の実施例について説明する。ここでは、柱状構造上に保護膜を有する無機波長板を作製し、保護膜の密着性、及び高温高湿試験における反射率の変化量について、評価した。なお、本発明はこれらの実施例に限定されるものではない。
図3に示すフローチャートに基づいて、図2に示す無機波長板を作製した。先ず、ガラス基板に対してマッチング膜を形成した。次に、マッチング膜の形成されていないガラス基板の反対面に対して、反射防止膜を形成した。次に、マッチング膜上にTa2O5からなる斜方蒸着膜を形成し、100℃以上300℃以下の温度でアニール処理した。
JIS K5600に準拠し、反射防止膜上から直角の格子パターン(25マス)を切り込み、複屈折膜まで貫通させた後、反射防止膜上にテープを貼り、テープをはく離した。テープのはく離に対する保護膜の耐性を、剥がれレベルとしてJISK 5600に準拠する分類0〜5に評価した。
比較例1の無機波長板の複屈折膜への保護膜成分の侵入量は0nm、実施例1〜4の無機波長板の複屈折膜への保護膜成分の侵入量はそれぞれ3nm、5nm、10nm、16nmであった。
