[00142604]全介质F-P窄带消偏振滤光片

一种全介质F?P窄带消偏振滤光片,其特征在于是由透明基底、高反射膜、双轴各向异性间隔层和高反射膜一体构成,高反射膜的最外层为高折射率层。基本结构是：高反射膜︱各向异性间隔层︱高反射膜。本发明中双轴各向异性间隔层的引入为光波斜入射条件下全介质F?P窄带消偏振滤光片提供了新的设计方法。 | An all-medium F-P narrow-band depolarization optical filter is characterized by being integrally composed of a transparent substrate, a high-reflectance film, a biaxial anisotropic spacer layer and a high-reflectance film, and a high-reflective-index layer is arranged on the outermost layer of the high-reflectance film. The basic structure of the filter is the high-reflectance film-the anisotropic spacer layer-the high-reflectance film. Due to introduction of the biaxial anisotropic spacer layer, a new design method is provided for the all-medium F-P narrow-band depolarization optical filter under the optical wave oblique incidence condition。
