產品系列說明

優異的真空紫外（VUV）穿透率
150nm - 6μm範圍高穿透率
低折射率

ISP Optics 公司的氟化鋰（LiF）窗鏡在 150 - 200nm 的真空紫外（VUV）波段以及在氫萊曼-α譜線（121nm）擁有出色的穿透率。除了在紫外波段擁有高穿透率外，這些窗鏡在可見光及 6µm 以下的紅外波段的穿透率也非常出眾。氟化鋰具有較低的折射率，因此氟化鋰窗鏡可在無抗反射（AR）鍍膜的情況下使用。ISP Optics 氟化鋰窗鏡（LiF）非常適合用作光譜應用中的紫外穿透窗鏡、X 射線光譜儀中的繞射元件或熱成像應用中的紅外窗鏡。

請注意: 氟化鋰對熱衝擊很敏感，溫度高於 400°C 時會受到大氣中水分的侵蝕。
