Abstract
Description
特に、精密機器用途においては、本発明の紫外線透過ガラスの厚みは0.2〜1.0mm、0.3〜0.6mmとすることがより好ましい。一方、大型装置の用途においては、本発明の紫外線透過ガラスの厚みを0.5mm以上、より好ましくは0.5〜2.0mmとすることが強度剛性を担保する観点から好ましい。なお、一般的に紫外線透過率はガラスの厚みが厚いほど低下するが、本発明の紫外線透過ガラスは250nm以下の波長領域において高い透過率を有するために、従来品に比べ厚みを増加させても同波長域において高い透過率を維持可能である。

- 請求項1〜5の何れかに記載の紫外線透過ガラスの製造方法であって、ガラス原料の少なくとも一部として合成シリカを用いることを特徴とする、紫外線透過ガラスの製造方法。
- 前記合成シリカが、気相反応法または液相反応法により生成された粒体シリカである、請求項6に記載の紫外線透過ガラスの製造方法。
- 前記合成シリカの平均粒径が100μm以下であり、
