Title: Grid polarizer
Inventor: KOEDA MASARU
IPC: G02B5/30
Filed: 1989-08-29
Abstract: PURPOSE:To obtain the grid polarizer which covers a wide wavelength range, is less deteriorated in polarization characteristic with respect to an incident angle and has the excellent polarization characteristic by forming parallel line patterns of a high density consisting of conductors on both surfaces of a substrate having a high transmittance to measuring light and forming the patterns in such a manner that the arranging directions of the grids on both surfaces of the substrate are parallel. CONSTITUTION:This grid polarizer is formed by arranging the Au grid patterns 3 on both surfaces of, for example, the KRS-5 substrate 1 subjected to polishing on both surfaces in such a manner that the arranging directions of the patterns are parallel on both surfaces of the substrate. The Ni-Cr patterns 2 of 20Angstrom  thickness are formed between the KRS-5 substrate 1 and the Au grid patterns 3 for increasing an adhesion between the substrate and Au grid patterns. The KRS-5 substrate 1 has the good transmittance over the entire IR region and the good transmittance even in a visible region and is transparent in the region of about 0.6 to 60mum. The transmittance in this region is about 70%. The performance of the grid polarizer is improved in this way and the use up to the long wavelength side of the visible region is possible.
