When the interference film is applied to the side incidence, it will cause obvious optical wave oscillation in different directions, especially in the closed adhesive prism. With the help of this kind of polarization phenomenon, different kinds of polarization splitting prisms have been developed. Such phenomena are based on the constant appearance of the specified charge and the radial equilibrium of the magnet at each layer of the film. Facing the s-polarization splitting prism and the charge field longitudinal oblique interface, the feasible refractive index of the layer is equivalent to the multiplication of the realistic refractive index and the cosine of different reflection angles; Facing the p-polarization splitting prism, the charge field is horizontally transmitted through the interface, and the feasible refractive index of the layer is equal to the real refractive index divided by the cosine of the negative reflection angles
the construction theory of the polarization splitting prism is to search for an inclination angle. When a cluster of horizontal beams irradiates in this direction, the transmittance of the substrate and the film to the p polarization splitting prism is the same. Such a special angle is called the Brewster angle of the film. This requirement can be established only when the light beam is scattered from a high conductivity medium to several layers of film in the face of real film raw materials. Therefore, the multi-layer film is usually connected to the plate inside the glass prism. Therefore, only when the feasible refractive index of the p-polarization splitting prism is the same, the two different materials can meet the requirements of Brewster angle. Under such factors, the transmittance of the p-polarization splitting prism is completely dissipated, and several layers of film stacks built by overlapping two types of materials will not refract the p-polarization splitting prism at all
