Abstract

PURPOSE:To enable to appropriately obtain a total spectro RF even if a fluorescent color is contained, by a method wherein a spectro reflection refelectance factor (RF) of a sample is measured in a reflection measuring manner, and a spectro fluorescence RF is measured in an radiation measuring manner. CONSTITUTION:A mirror 6 reflects a light from a light source 1 through a lens 2, a slit 4, and a concave diffraction grating 5, and the light enters into an integrating sphere 8 through the diffraction trating 5, the slit 4, and a half mirror 3 again. The light, which disperses in the integrating sphere 8 and is reflected in a stream line direction of a sample 9, disperses at a concave diffraction grating 12 through a half mirror 10 and a slit 11, and is inputted to a light-receiving element group 13. After the relative spectro sensitivity of the light-receiving element group 13 is found, a standard white plate, containing no fluorescent color, is placed at a sample surface 9 of the integrating sphere 8 to find a spectro distribution. Then, after the spectro distribution is measured on the sample surface 9, a light-shielding plate 7 is placed in front of the mirror 6, and a measurement takes place as the light is shielded in order from a short wavelength side of a spectrum. Processing of the data by means of a signal processing part 35 permits obtaining of a total spectro RF of the sample.
