特長
- 30 arcminのウェッジウィンドウ
- Ø12.7 mm(1/2インチ)およびØ25.4 mm(1インチ)ウィンドウをご用意
- ARコーティング付きのタイプやカスタム仕様のサイズもご提供可能です。詳細は当社までお問い合わせください。
当社では、コーティング無しのØ12.7 mm(1/2インチ)およびØ25.4 mm(Ø1インチ)フッ化マグネシウム(MgF2)ウェッジウィンドウをご用意しております。ウェッジ付き光学素子はフリンジパターンの発生をなくし、また、面間における共振を防ぐのに役立ちます。ウィンドウはレーザ出力を外部の影響から保護でき、また、ビームサンプリングの用途で使用する際に便利です。 様々な基板材料やコーティングの平面ウィンドウもご用意しております。
MgF2ウィンドウは深紫外線の用途や、さらには真空紫外線の用途にも適しています。120 nmで50%以上の透過率を達成し、エキシマレーザーシステムと一緒に用いる用途や、121 nmの水素ライマンα線を使用する用途に適しています。当社のMgF2 ウィンドウは、紫外線A(UVA)、紫外線B(UVB)、可視および赤外線(IR)領域でも使用でき、200～1000 nmにおいて約94%の透過率、1～6 µmにおいて約95%の透過率を達成します。複屈折を最小限に抑えるため、当社のMgF2 ウィンドウは、結晶軸が光軸に平行になるようにカットされています。
こちらでご紹介しているMgF2ウェッジウィンドウの他に、異なる基板材料を使用したウェッジウィンドウもご用意しております(右のセレクションガイドをご参照ください)。また、一般的なレーザ波長域に対応したARコーティングを施したウェッジ付きレーザーウィンドウや、片面のみ広帯域ARコーティングを施したウェッジ付きビームサンプラもございます。 当社の標準的なARコーティングや、カスタム仕様のサイズ、厚さ、ウェッジ角にも対応可能です。詳細は当社までお問い合わせください。
