Polarizing filter, and method for fabricating same

摘要

A polarizing filter with a gapless polarization separating filter layer formed between a plane of incidence and a plate of transmission of the filter, the polarization separating filter layer being formed by connecting first filter layer sections alternately and crosswise with second inclined filter layer sections in an approximately zigzag shape. The filter is free of the problem of light leakage and can perform the functions of a polarizing filter satisfactorily.
