Description
光学ベース素子と、
少なくとも1つの二色性染料を含有する、配向された少なくとも1つの偏光膜を組み込んだ層状構造と、
光学品質の感圧材料の少なくとも1つの層を備えた層状構造であって、前記構造を光学ベース素子の表面に永続的に保持するように光学ベース素子の一方の表面と偏光膜を含む層状構造との間に配置された層状構造と
を備えた偏光光学素子が提供される。
/a1/ 層3の一方の面を露出させるために2つの剥離可能ライナーのうちの一方を剥離するステップ
/b1/ 層3の2つの剥離可能ライナーのうちのもう一方を介して、層3の露出した面をレンズ1の前面に押し付けるステップ
/c1/ 層3のもう一方の面を露出させるために2つの剥離可能ライナーのうちのもう一方を剥離するステップ
/a2/ 接着剤層3の第1の面を露出させるために2つの剥離可能ライナーのうちの一方を剥離するステップ
/b2/ 層3の2つのライナーのうちのもう一方を介して、層3のこの第1の露出した面を偏光構造2に押し付けるステップ
/c2/ 層3の第2の面を露出させるために2つの剥離可能ライナーのうちのもう一方を剥離するステップ
− とりわけ層状構造がPVAをベースとする偏光膜のみで形成されている場合、つまり、保護膜を備えていない場合、層状構造を光学ベース素子に押し付ける前に、制御された方法で偏光膜を湿らせることができる。このように偏光膜を湿らせることにより、偏光膜をより容易に光学ベース素子の表面の曲率に一致させることができる。
− 接着構造3は、インサート膜、たとえば厚さ10μmのPET膜によって分離された、同じタイプまたは異なるタイプの光学品質の2つの「感圧」接着剤層を備えることができる。複合接着構造3がレンズ1の上にアセンブルされると、複数の接着剤層のうちの1つが光学ベース素子とインサート膜の間に置かれ、また、接着剤の他の層がインサート膜と偏光構造の間に置かれる。2つの個別感圧接着剤に基づくこのような構成により、これらの接着剤の選択を互いに独立して最適化することができ、それにより、一方では偏光構造に対する優れた粘着を得ることができ、また、他方では光学ベース素子、さらにはインサート膜の両面に対する優れた粘着を得ることができる。
− 層状構造中に存在するあらゆるひずみを小さくするために、偏光構造が光学ベース素子に押し付けられた後に、得られた偏光光学素子を加熱することができる。このような加熱は、たとえば80℃のオーブンの中で1時間にわたって実行することができる。
− 光学ベース素子に結合された偏光構造が偏光膜のみで形成されている場合、偏光膜を保護するために、引き続いて偏光膜に機能コーティングを施すことができる。このようなコーティングは、詳細には、とりわけ光学および眼科学分野で広く使用されている耐衝撃コーティングまたは摩耗防止コーティングであってもよい。
[実施例1:屈折率が1.665、ジオプターベースが6.75の偏光眼科用レンズの製造]
レンズまたは湾曲した膜のベースは、屈折率が1.53であり、また、同じ曲率を有する平凸レンズの屈折パワーとして定義されている。
偏光層状構造2は、TEG1465DUの参照の下でNitto Denkoによって製造された、厚さ約20ミクロンのポリアクリラートPSA層を備えた三酢酸セルロース/PVA/三酢酸セルロースタイプの偏光膜である。偏光層状構造2は、約110ミクロンの厚さを有しているため、この商用膜の総合厚さは約130ミクロンである。偏光膜の一方の面および反対側の面に、それぞれ、可撓性で、かつ、除去可能な2つの追加保護膜が置かれている。
