POLARIZATION ULTRAVIOLET LIGHT IRRADIATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a polarization ultraviolet light irradiation device that prevents ingress of foreign matter into an object to be irradiated.SOLUTION: A polarization ultraviolet light irradiation device 1 includes an irradiator 6 including a linear ultraviolet light source 7, a reflection mirror 8 for reflecting ultraviolet light, and a wire grid polarizer 10 for changing emitted ultraviolet light to linear polarization. The polarization ultraviolet light irradiation device 1 comprises a rotation mechanism 60 configured such that until an object 2 to be radiated is carried to a position below the irradiator 6, the object 2 is rotated by a predetermined angle with respect to the axis L of the light source 7.
