<p>PROBLEM TO BE SOLVED: To provide a pseudo-sunlight irradiation apparatus which can be miniaturized as a whole, which does not use a high-cost acrylic plate and which can reduce the usage number of optical filters, and to provide a pseudo-sunlight irradiation apparatus in which light source means are combined properly so as to be formed, when a large irradiation face is required. SOLUTION: A lamp 2, such as a xenon lamp 2 or the like, is installed in a light-shielding box body 1 having a light emission face, whose area is smaller than the irradiation rage of pseudo sunlight. A pseudo-sunlight irradiation box C in which an optical filter 4 is attached to the light emitting face is installed, so as to be directed to an object to be measured, made to be supported by a frame 9. The lamp 2 is turned on, and the object A, to be measured, being placed in the irradiation range is irradiated with the pseudo-sunlight.</p> |
