当社の臭化カリウム(KBr)精密ウィンドウはØ12.5 mmとØ25 mmのサイズでご用意しております。臭化カリウムは広い波長範囲において透過率が高く、機械的な衝撃や300 °Cまでの温度に対して高い耐性があります。しかしKBrは水溶性であるため、高湿度環境などにおける湿気から保護する必要があります。KBrウィンドウは透過波長範囲が広いため、FTIR分光法に適しています。

光学素子を取扱う際は、常に手袋をご着用ください。特に臭化カリウム製光学素子の場合は、水分が表面にダメージを与える場合があります。

当社では、様々なレーザや産業用としてお使いいただける、種々の基板材料を用いた高精度ウィンドウを取り揃えています。当社のラインナップについては右のFlat Window Selection Guideの表をご覧ください。また一般的なレーザ波長用にARコーティングしたレーザーウィンドウや、P偏光の反射を除去するブリュースターウィンドウもご用意しております。
