摘要
以ZF6为基底, 采用电子束蒸发物理气相沉积方法设计并制备了一种增透波长为04~08 μm的宽谱带可见光区增透膜。薄膜材料仅含有TiO2和SiO2两种材料, 分别作为高低折射率材料。利用Edinburgh光谱仪对双面镀制该膜系样品的透过率进行测量, 测试结果表明: 薄膜平均透过率达9815%, 实际样品的光学特性与设计结果基本相符, 具有宽带的增透特性, 减少了表面剩余反射。机械强度与环境测试表明: 制备的薄膜具有良好的稳定性和牢固度, 可以应用于可靠性要求较高的光学系统中。
Abstract
A type of wideband anti-reflection film in the visible light spectrum from 04 μm to 08 μm was designed based on a ZF6 substrate, then the coatings were fabricated by Electron Beam Physical Vapor Deposition(EBPVD). Two types of coating materials, titanium oxide(TiO2) and silicon oxide(SiO2), were treated as high index and low index materials, respectively to use in this process. Edinburgh spectrometer was used to measure the transmittance of the sample which was coated the anti-reflection coatings on both side. The test result indicates that its average transmittance is about 9815%. It shows wideband anti-reflection characters and little surface residual reflection, and almost accords with the designing result. The measurement of stability and firmness indicates that the coatings have good performance, which makes it possible to be used in some rigorous optical systems.
