本文阐述了化学镀双层增透膜膜层质量与工艺因素的关系,分析了膜层常见疵病的产生原因,并且提出了一些克服的办法;指出了实际使用与《光学零件工艺手册》中,关于钛酸乙酯溶液和硅酸乙酯溶液的时化时间的差别;介绍了控制膜层光学厚度的经验公式。 This article elaborates the relationship between the quality and the technical factors of the electroless plating double antireflection film, analyzes the causes of the common defects in the film, and puts forward some ways to overcome them. It points out that the actual use and the “Optical Parts Process Manual” , About the time difference between the ethyl titanate solution and the ethyl silicate solution; and the empirical formula for controlling the optical thickness of the film is introduced.
