分光膜层

分光膜层


分光镜是一种能够将光线一分为二的光学件,莱普可以根据客户的要求镀制偏振分光膜层,非偏振分光膜层,可以满足高功率激光要求和拥有高的消光比。

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.
