Abstract
This invention has the polarizing function of polarizing an input beam and a non-reflecting function of suppressing reflection of the input beam, wherein at least one side of a light-transmissive substratehas a polarizing portionwith a striped structure formed by multiple alternating light-transmissive dielectric layers. . . and metallic film layers. . . . Its characteristics are improved if the metallic film layers are very thin and flat, with a target thickness in the range from 5 to 20 nm and variation of film thickness within the range of ±10%.
