PROBLEM TO BE SOLVED: To provide a light irradiation device in which light irradiation with even illuminance and of given wavelength is enabled.SOLUTION: A light illumination device includes: a lamp 4; a reflector 5 of condensed type that reflects light radiated from the lamp 4; and a polarizer unit 10 that polarizes direct light from the light source 4 and reflection light reflected from the reflector 5, and projects the light polarized by the polarizer unit 10. A wavelength cut filter 7 is provided between the lamp 4 and the polarizer unit 10, and the wavelength cut filter 7 has a convex shape protruding toward the lamp 4.SELECTED DRAWING: Figure 5 |
