Abstract

　プラスチック製の対物レンズを有しながらも温度特性を良好に維持しつつ、短波長の光束を用いて光ディスクに高密度に情報の記録及び／又は再生を行える光ピックアップ装置用の対物レンズ及び光ピックアップ装置を提供するために、（４）式を満たすように波長特性を若干犠牲にして、（３）式を満たすように温度特性を良好として、温度変化が生じても球面収差の発生を抑えることができる対物レンズを創成したのである。このような良好な温度特性は、３以上３０以下の数の輪帯から構成され、かつ、隣り合う輪帯同士が入射光に対して所定の光路差を生じるように形成された輪帯構造を、対物レンズの光学面に備えることで得ることができる。
