类金刚石碳 (DLC) 镀膜硅窗口片
Ø满足 MIL-F-48616 和 MIL-C-48497C 的严重磨损要求
Ø3 – 5µm 的高透射率
Ø恶劣环境的理想选择
Ø也提供类金刚石碳 (DLC) 镀膜锗窗口片
类金刚石碳 (DLC) 镀膜硅窗口片在一个表面提供抗反射镀膜,在另一个表面提供专门设计的 DLC 镀膜,使这些窗口片非常耐用,是恶劣环境的理想选择。 DLC 镀膜表面设计用于承受从 -80 到 +160°F 的温度循环、持续 72 小时的盐雾以及沙子和泥浆混合物中 1,000 次擦拭器振荡。 此外,这些窗口片符合 MIL-F-48616 和 MIL-C-48497C 对严重磨损的要求。 硅具有 1150 的努氏硬度和低密度,使其比锗基板更坚固,并且分别适用于对重量敏感的应用。 类金刚石碳 (DLC) 镀膜硅窗口片设计为 3 至 5μm,非常适合红外防御应用,例如热成像。
