一、前言随着科学技术的不断发展,窄带滤光片应用的范围愈来愈广,这就对滤光片的性能提出了各种各样的要求,不但要求它有好的光学性能,而且要求它具有好的膜层牢固性和光谱稳定性。目前在干涉滤光片的使用和贮存过程中,最突出的问题是其光谱稳定性。如果说,一块干涉滤光片的光学参数(λ_0、δ_(λ0.5)、T_0等)随时间而变化,那么我们借此测量的数据将前后有矛盾,借此控制的仪器将失灵,……等等。这当然是不能允许的!例如在分离激光辐射时,滤光片峰值透过波长甚至不允许有几个埃的变化。但是,目前用电阻加热法镀制的滤光片其
I. Introduction With the continuous development of science and technology, narrowband filter applications more and more widely, which put forward a variety of filter performance requirements, not only requires it to have good optical properties, and It requires good film firmness and spectral stability. Currently the most prominent issue in the use and storage of interference filters is their spectral stability. If we say that the optical parameters (λ_0, δ_ (λ0.5), T_0, etc.) of an interference filter change over time, then the data we take from this measurement will be contradictory. …and many more. This of course is impermissible! For example, when separating laser radiation, the filter peak transmission wavelength does not even allow for a few Angstroms change. However, the current use of resistance heating method of plating filter it
