将窄带透过的介质干涉滤光片与保护片相胶合,是为了降低其光学特性随时间而产生的变化。可是,在胶合过程中,滤光片上产生峰值透过波长λ_(max)的跳跃式的位移,使δλ半宽度约增大20％。此外,还可观察到,胶合后的滤光片的λ_(max)有随时间而产生的不可控制的迁移。作者研究了引起滤光片胶合时λ_(max)变化的一些因素,并试图 The narrowband dielectric interference filter and the protective sheet are glued in order to reduce their optical properties over time. However, during the gluing process, a sharp shift of the transmission wavelength λ max occurs on the filter, increasing the δλ width by approximately 20%. In addition, it is also observed that the λ max of the glued filter has an uncontrollable migration over time. The authors studied some of the factors that caused the change in λ max in the filter to be glued and attempted
