    • An optical element that has a flat plate shape and includes a light entering surface and a light exiting surface substantially parallel with the light entering surface, the element includes a plurality of translucent members, a plurality of optical multilayer films, a plurality of phase plates, and a plurality of plasma polymerized films. The translucent members, the optical multilayer films, the phase plates, and the plasma polymerized films are provided along the light entering surface and the light exiting surface. The translucent members include a plurality of oblique surfaces oblique to the light entering surface and the light exiting surface. Each of the optical multilayer films is formed on some of the oblique surfaces. The optical multilayer film is either one of a polarization separating film and a reflecting film. Each of the plasma polymerized films is formed on at least one of a surface of each of the oblique surfaces, a surface of the optical multilayer film, and a surface of each of the phase plates. At least one of each of the translucent members adjacent to the optical multilayer film and the optical multilayer film, the translucent member adjacent to the phase plate and the phase plate, and the phase plate adjacent to the optical multilayer film and the optical multilayer film is molecular-bonded with the plasma polymerized film.
    • 一种光学元件,具有平板形状并且包括光入射表面和与光入射表面基本平行的光出射表面,所述元件包括多个透光构件,多个光学多层膜,多个相位板, 和多个等离子体聚合膜。 半透明构件,光学多层膜,相位板和等离子体聚合膜沿着光入射表面和光出射表面设置。 半透明构件包括与光入射表面倾斜的多个倾斜表面和光出射表面。 每个光学多层膜形成在一些倾斜表面上。 光学多层膜是偏振光分离膜和反射膜中的一种。 每个等离子体聚合膜形成在每个倾斜表面的表面,光学多层膜的表面和每个相位板的表面中的至少一个上。 与光学多层膜和光学多层膜相邻的半透明构件中的至少一个,与相位板和相位板相邻的半透明构件以及与光学多层膜和光学多层膜相邻的相位板是 与等离子体聚合膜分子键合。
