Abstract
【解決手段】複数枚の複屈折板を貼り合わせて成る1/2波長板において、材質が水晶の4枚の複屈折板が、各複屈折板の主面同士を貼り合わせた形態で形成されており、且つ各複屈折板の厚み比が、入射又は出射側の複屈折板から、1:2:1:1である1/2波長板。
【選択図】図1
Description
図1は、本発明における1/2波長板を示した外観斜視図である。図2は、実施例に開示した本発明の実施形態の1/2波長板における、各複屈折板の光学軸方位を示した方位図である。図3は、本発明における1/2波長板における、波長−PS変換効率特性を示したグラフであり、比較のために同グラフ内には従来の1/2における同特性グラフも示している。尚、各図においては、説明を明りょうにするため構造体の一部を図示せず、また寸法も一部誇張して図示している。特に図1における各複屈折板の厚み寸法は誇張して図示している。
