补充资料：减反射膜
| 减反射膜 antireflecting film 涂敷在透明光学元件表面、用来消除或减弱反射光以达增透目的的光学薄膜。又称增透膜。最简单的减反射膜是单层介质膜，其折射率一般介于空气折射率和光学元件折射率之间，使用最普遍的介质膜材料为氟化镁。减反射膜的工作原理是基于薄膜干涉原理。入射光在介质膜两表面反射后得两束相干光，选择折射率适当的介质膜材料，可使两束相干光的振幅接近相等，再控制薄膜厚度，使两相干光的光程差满足干涉极小条件，此时反射光能量将完全消除或大大减弱。反射能量的大小是由光波在介质膜表面的边界条件确定，适当条件下可完全没有反射光或只有很弱的反射光。单层减反射膜只能对某个波长和它附近的较窄波段内的光波起增透作用，为在较宽的光谱范围达到更有效的增透效果，常使用多层介质膜。常见的多层膜系统是玻璃-高折射率材料低折射率材料-空气，简称gHLa系统。H层通常用二氧化锆（n＝2.1）、二氧化钛（n＝2.40）和硫化锌（n＝2.32）等，L层一般用氟化镁（n＝1.38）等。 减反射膜广泛用于各种光学元件的表面处理，例如照相机镜头上涂减反射膜后，可减少由反射引起的杂散光并显著增加像的亮度。 |
