Abstract
Provided is a weathering test instrument that includes: a light source section including a plurality of solid-state light-emitting elements, in which the solid-state light-emitting elements are different in kind from one another, and are configured to emit light beams having respective wavelength regions that are different from one another; a light receptor configured to receive the light beams radiated from the light source section individually for the respective wavelength regions; and a controller configured to control radiant intensities of the respective solid-state light-emitting elements individually, based on received light amounts for the respective wavelength regions derived from the light receptor, and thereby control irradiance at a sample surface for each of the wavelength regions to allow an accelerated test of a sample to be performed.
