ABSTRACT:
An artificial crystal double refraction plate is attached to the top of a package having a solid state imaging device chip. The artificial crystal double refraction plate protects an imaging surface and has an optical low-pass effect. An IR cut coating is applied on the surface of the artificial double refraction plate. Another two artificial crystal double refraction plates are arranged separately from the artificial crystal double refraction plate attached to the package. These three artificial crystal double refraction plates achieve desired optical low-pass effects in horizontal and vertical directions.
