Abstract
【解決手段】予め選択された長さ及び幅のシームレスのディヒューザのシートを作製するための中空の円筒形のシームレスの金属マスタ(604)。本発明の追加の様相は、中空の円筒形のシームレスの反転可能なエラストマー系マスタ(402)及びそれを作る方法並びに感光媒体に可変のディヒューザの記録をもたらす装置及びプロセスを有する。
【選択図】図28
Description
幾つかの態様を有する本発明は、光成形ディヒューザ(拡散器)分野に関し、また、シームレスマスタ及びディヒューザフィルムのシーム複製(seam replication)とともに、その同様のもの、すなわち、区切り点又はマークのない連続した光成形被覆を作製する方法に関する。
ディヒューザマスタは、それを通じて伝送される光に望ましく光学的に作用し得る膨大な種類の光成形ディヒューザを作製するのに用いられる。
我々は、ディヒューザ及びそれらに関連したディヒューザ−マスタの縁部境界である「干渉」パターンと関係する種々の問題を、簡単に言えばシームレスマスタ及びそれを作製する方法である本発明を用いて解決した。我々の発明は、簡単に要約すると、3つの態様を有している。
以下、本発明の実施の形態について、添付図面を参照しながら説明する。
必要な場合、ピンホールフィルタ上に置かれた適切な対物レンズ(標準的には20X〜60X)をセットする。適切なテーブル上で、中間マスタディヒューザホルダを所定位置に置く。ここでは、中間マスタディヒューザをしっかりと固定する。好適な散乱角によって、適切な中間マスタをホルダ上に置く。最終マスタ及びそれに関連するマスタを所定位置に置く。ここでは、ホルダをしっかりと固定する(例えば接着剤で接合する)。テーブルに示されるように、大きな比率の楕円形のディヒューザマスタに関してセットアップする場合には、3〜9インチ(約76.2〜228.6ミリメートル)の広さで、「ソフトな」エッジのフォーカスをなすように、対物レンズに続き、円筒レンズをセットする。中間マスタの中央に対してスリットビームを指向させる。それた光が最終マスタ上に位置するのを防止するために、全ての遮蔽部材を配置する。最後に、約30μミリワットを読み出すべく、最終マスタへの干渉光を調整する。
