当社ではØ12.7 mm(Ø1/2インチ)およびØ25.4 mm(Ø1インチ)ウェッジ付きシリコン(Si)ウィンドウをご用意しております。 こちらの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。 ウィンドウはコーティング無しまたは 2～5 µm用ARコーティング付きです。また当社では、平面ウィンドウ も様々な基板材料とコーティングでご用意しております。
シリコン(Si)は、近赤外域や中赤外域の一部で使用する用途に適した光学材料です。 高い熱伝導性と低い密度により、レーザーウィンドウに適しています。 ただし、このウィンドウはチョクラルスキ法によるシリコン(OCz-Si)を使用して製造しているので、9 µmで強い吸収帯があり、テラヘルツ周波数では透過率が低くなります。そのため、CO2レーザの透過用途やテラヘルツ用途でのご使用には適しません。
こちらでご紹介しているシリコン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(上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もございます。 他には、広帯域ARコーティングが片面のみに施されているウェッジ付きビームサンプラもご用意しております。また、カスタム仕様のサイズや厚さのウェッジウィンドウもご提供可能です。詳細は当社までお問い合わせください。

(posted 2021-01-05 20:17:56.7) which surface is the wedge surface? YLohia
(posted 2021-01-13 11:31:58.0) Thank you for contacting Thorlabs. If the window is not engraved with an arrow on the edge pointing to the wedged side, you can rest the optic on a flat table on top of graph paper or lined paper. Then look for the reflection of the lines in the surface reflection. Tilt the window so that, on the flat side, the lines in the reflection are parallel to the lines on the paper. As the optic rolls, this will still be true on the flat side. On the angled side, the lines in the reflection will process around the lines on the paper when it rolls. j.travers
