补充资料：光学薄膜
| 光学薄膜 optical coating 由薄的分层介质构成的，通过界面传播光束的一类光学介质材料。光学薄膜的应用始于20世纪30年代。现代，光学薄膜已广泛用于光学和光电子技术领域，制造各种光学仪器。 光学薄膜的特点是：表面光滑，膜层之间的界面呈几何分割；膜层的折射率在界面上可以发生跃变，但在膜层内是连续的；可以是透明介质，也可以是吸收介质；可以是法向均匀的，也可以是法向不均匀的。实际应用的薄膜要比理想薄膜复杂得多。这是因为：制备时，薄膜的光学性质和物理性质偏离大块材料，其表面和界面是粗糙的，从而导致光束的漫散射；膜层之间的相互渗透形成扩散界面；由于膜层的生长、结构、应力等原因，形成了薄膜的各向异性；膜层具有复杂的时间效应。 光学薄膜按应用分为反射膜、增透膜、滤光膜、光学保护膜、偏振膜、分光膜和位相膜。常用的是前4种。光学反射膜用以增加镜面反射率，常用来制造反光、折光和共振腔器件。光学增透膜沉积在光学元件表面，用以减少表面反射，增加光学系统透射，又称减反射膜。光学滤光膜用来进行光谱或其他光性分割，其种类多，结构复杂。光学保护膜沉积在金属或其他软性易侵蚀材料或薄膜表面，用以增加其强度或稳定性，改进光学性质。最常见的是金属镜面的保护膜。 |
