Abstract
A reaction curable resin is irradiated with ultraviolet light having wavelengths of 250 to 380 nm. A screen image of luminance value, which is obtained by extracting only a specific wavelength component of the reflected ultraviolet light, is recorded, and the cured state of an ultraviolet curable resin is quantified from a captured image and displayed. At the same time, the spectral characteristics of reflected light are measured by an ultraviolet spectroscope and a cured state is quantified in accordance with the change rate of absorbances obtained from a change of spectral characteristics by combining the spectral characteristic with a luminance value image and displayed.
