製品群全体の紹介

  • 複数の波長域をラインナップ
  • 広い波長域にわたりフラットな特性
  • λ/4 とλ/2 のリタデーション
  • 黒アルマイト仕上げの金枠に固定

アクロマティック波長板 (位相差板) は、使用する光の波長に依存せず一定の位相シフトを実現します。この波長非依存性は、2種類の異なる結晶材料を用いることで実現されます。入射光の波長が変化しても、各結晶毎に生じる位相シフト量が互いを相殺するため、結果的に波長依存性がなくなります。アクロマティック波長板 (位相差板) のフラットな特性は、チューナブルレーザーや多波長レーザーシステム、および他の広帯域波長光源との使用に理想的です。 

0°の入射角で用いるためにデザインされ、入射角が±3°ずれた場合でも位相ずれは1% 未満に収まります。23mmの開口径を持つ波長板は、2種類の結晶材料を接着で貼り合わせています。どのアクロマティック波長板 (位相差板) も、高速軸 (進相軸) を示すマーキングが付いた、黒アルマイト仕上げの金枠内に固定されます。

波長板と位相差板の理解

波長板と位相差板の用語、仕様、製作、構造。及び、正しい波長板の選定やアプリケーション事例について。位相差板としても知られる波長板は、光を透過し、ビームを減衰、偏位、あるいは変位させることなく、その偏光状態を修正します。波長板は、偏光の一つの成分をそれが直交する成分に対して位相を遅らせる (遅延させる) ことによって偏光状態を変化させます。
