摘　　要：分光膜在倾斜使用时会存在较强的偏振效应，通常采用各种措施来减小这种偏振效应的影响，但基本上只能在单一波长或较窄波段范围内实现消偏振分光，其波段范围几乎不超过50nm。根据设计要求运用解析法设计出一个合适的初始膜系，再在所设计的初始膜系基础上，运用TFCalc膜系设计软件采用解析法、Needle和变尺度优化法综合设计了45。入射1260～1360nm波段7：3消偏振分光膜，分析了该设计膜系的监控曲线以评价其可镀制性，并采用德国莱宝APS1104型镀膜机对所设计的膜系进行了实际镀制，获得了性能优良的45。入射宽波段7：3消偏振分光膜。The polarization effect is inevitable when light-splitting film is titled. Any effective measures were usually taken to reduce the influence of polarization effect, but only single wavelength or very narrow spectral range can realize non-polarizing, the spectral range was almost no more than 50 nm. An initial formula was designed by resolution method according to the design target, Then, the incidence of angle with 45° light-splitting film from 1 260 nm to 1 360 nm spectral range was designed by resolution, needle and variable metric optimization methods on the designed initial formula by using TFCalc formula design software. The monitoring transmittance curve of designed formula was analysed to decide whether it could be deposited. The formula was deposited by the type APSll04 deposition machine made in Germany, light-splitting film with good performance was acquired.
