特長

  • λ = 200 nm~6 μmで透過率≥ 94%
  • 波長120 nmにおいても、透過率>50%
  • Ø12.7 mm(Ø1/2インチ)およびØ25.4 mm(Ø1インチ)バージョンから選択可能

フッ化マグネシウム(MgF2)製のウィンドウはØ12.7 mm(Ø1/2インチ)、Ø25.4 mm(Ø1インチ)のサイズが用意されています。これらは、深紫外域から中赤外域で高い透過率を有しています。このウィンドウは非常に耐久性があり収差を最小に抑えることができます。フッ化マグネシウム(MgF2)ウィンドウは光軸が結晶のC軸に平行になるようにカットされており、複屈折が最小に抑えられています。

フッ化マグネシウム(MgF2) ウィンドウは真空UV域範囲を含む深紫外(UV)域にお使いいただけます。120 nmでも>50%の透過率が得られるので、エキシマレーザ、また 121 nmで水素ライマンα線適用の製品とのご使用に適しています。UVA、UVB、可視域または赤外域(200~1000 nm)では、約94%の透過率、波長範囲1~6 µmでは約95%の透過率を示します。
