偏光光线照射装置;POLARIZATION LIGHT IRRADIATION APPARATUS

摘要

提供一种可进一步改善照度不均之偏光光线照射装置。;偏光光线照射装置1系具备有线状之光源4、对该光源4之光进行聚光之导水管状之主反射镜5、及用于将所照射之光形成为直线偏光之线栅偏光器16，且在将偏光光线照射至照射对象物W之偏光光线照射装置1中，构成为于光源4之发光端P附近，设置有自光源4而延伸至线栅偏光器16附近之辅助反射镜6。;SOLUTION: A polarization light irradiation apparatus 1 is configured to have a linear light source 4, a cylindrical main reflecting mirror 5 condensing light of the light source 4 and a wire grid polarizer 16 for linearly polarizing light to be irradiated and to irradiate polarized light to an irradiation target object W, where an auxiliary reflecting mirror 6 extending from the light source 4 to near the wire grid polarizer 16 is provided near a light-emitting end P of the light source 4.
