分光膜是一种具有特殊光学性质的薄膜材料,它能够将入射的光按照不同的波长进行分离或合并。分光膜的设计和制造旨在实现光的分光和波长选择的功能,在分光镜和二向色镜(光学仪器内部组件)的制造过程中,通过镀制的分光膜实现不同波段的筛选和反射,广泛应用于光谱分析、光学仪器、光电子学、太阳能领域、显示技术以及光学涂层等多个领域。

镀膜类型 | 性能和应用 | |
分光膜层 | 偏振分光镜 | High reflection for s-polarized and antireflection for p-polarized for laser application. |
宽带偏振分光镜 | Wide wavelength bandwidth provide high reflection to s-polarized and antireflection to p-polarized. | |
非偏振分光镜 | The low polarization dependence of the metallic dielectric hybrid coating allows the transmission and reflection of S-polarization and P-polarization states to be within 6% of each other. |
