50:50の超短パルスレーザ用ビームスプリッタの透過ならびに反射ビームで分散のバランスを取るための1.0 mmウィンドウを用いた推奨構成(50 fs未満のパルスのみ)
特長
- Ø12.7 mm(Ø1/2インチ)およびØ25.4 mm(Ø1インチ)ウィンドウ
- 厚さ1.0 mm、3.0 mmまたは5.0 mm
- 300 nm～3 µmに平坦な透過率
- UV溶融石英(UVFS)とほぼ同じ材質特性
- 超短パルスにおける分散の調整に適した製品
こちらのコーティング無しのウィンドウは、光学石英ガラスの1種であるInfrasil®†製です。Infrasilは、UV溶融石英(UVFS)とほぼ同じ力学的、光学的特性を有しているため、UV溶融石英の代替品としてよく用いられています。InfrasilはUV溶融石英と比べ、1380 nm付近においてより高い内部透過率を有し、UV域から中赤外域においてはより平坦な透過特性を有します。また分散特性はほぼ同じです。上のグラフは、サンプルとして抽出したウィンドウの200 nm～3.2 µmにおける全透過率を示しています。
なおこちら光学素子はほかのウィンドウよりも薄く、厚みのある製品に比べて繊細ですのでご注意ください。また、標準的な止めネジ(セットスクリュ)型の光学マウントには薄すぎるため取り付けられません。ウィンドウを光学マウントに取り付ける時には、固定式光学マウントの場合と同様に、固定リングを用いて固定してください。
超短パルスでの利用
このウィンドウを超短パルスレーザ用ビームスプリッタUFBS5050と一緒にお使いになると、ビームスプリッタの透過ならびに反射アームの群遅延分散をほぼ同じにすることができます。 その他の超短パルスレーザ用ビームスプリッタでは、当社のInfrasilウィンドウは厚さが十分ではないため厳密に分散のバランスを取ることはできませんが、2つのビーム間の分散のバランスを向上させることは可能です。当社の厚さ4.0 mmのビームスプリッタに厚さ3.0 mmm(型番UDP053)または5.0 mmm(型番UDP105)のInfrasilウィンドウを使用して、ある程度の分散を補償することができますが、このビームスプリッタ向けに特別に設計されているわけではありません。

(posted 2021-02-03 21:50:38.763) Dear All,
I write from Aerial Photogrammetric Service of Chilean Air Force since we need to modify 2 G-IV for photogrammetry and remote sensing soon (this and next year). We have some doubts regarding the optical window and we are visualizing Infrasil as possible material.
For our digital camera we have a sort of requirements, The window should be around 60x 60 cm, fullfil M, Mil Specs MIL-W-1366F (ASG) Oct. 1975, S/D 80/50 and antireflective coating (e.g. RYN-1, RYN-B, AR106).
However we are considering a hyperspectral VNIR-SWIR for the near future. Some providers have suggested S/D 60/40 and the requirements of transmittance along the spectral range, however we have a doubt regarding the coatings. The above mentioned work up to ~1000nm and we would need to know if you provide another option suitable for the sensor we have and if having a coating or not would interfere with a hyperspectral sensor.
I would be very gratefull for any feedback
