在光学仪器、照相机镜头上增透膜已得到广泛应用。传统的光学增透膜有 MgF_2、A1_2 O_3 等,它们的光学折射率低,成膜稳定性差,增透频带窄,一般适用于制作单层增透膜。国际上近几年来,迅速发展起来的新颖增透膜镀料,是以 ZrO_2 为主要成份的混合镀料,它可以制作整个可见光范围内的多层增透膜,具有优良的增透效果。上海照相机总厂于1986年引进了西德LH 公司 A-1100真空电子束镀膜机及镀膜
In optical instruments, camera lens AR coating has been widely used. The traditional optical antireflection coatings are MgF 2, Al 2 O 3 and the like, which have low optical refractive index, poor film forming stability and narrow transmission band, and are generally suitable for single layer antireflection coatings. Internationally, in recent years, the rapidly developing new AR coating is ZrO 2 as the main component of the hybrid coating, which can make the entire visible light range of multilayer AR coatings, with excellent antireflection effect.
