產品系列說明

  • 在 200 至 3500nm 範圍內具有高穿透效果
  • 1 ppm 以下的 OH 內容物,可盡量減少吸收損耗
  • 10-5 表面品質及最高 λ/10不規則度 TWD

Suprasil® 窗鏡是以高純度的合成熔融石英製造,可在 200 至 3500nm 提供高度及平直的穿透效果。Suprasil 的機械屬性類似於熔融石英,其中的額外優點就是在可見光或紅外線光譜沒有吸收帶,因此在 1400 - 2700nm 之間沒有穿透損耗。相較於 Infrasil®,Suprasil 之中的 OH 內容物低於 1 ppm,因此吸收率較低,在搭配使用高功率雷射時,因為大量吸收造成的溫度上升非常有限,可忽略不計。Suprasil 窗鏡適用於雷射材料加工、醫療雷射應用,或是使用摻釹或 2 微米雷射的應用。
