Abstract
The measuring apparatus of the present invention measures the optical properties of a sample containing a fluorescent material by irradiating the sample with light containing a UV component. In the present invention are provided a first light source for irradiating the sample with light containing a UV component, a second light source for irradiating the sample with light which does not contain a UV component, light receiving element for receiving light reflected from the sample irradiated by said light sources, and output means for generating weighting coefficients for weighting the output of the light receiving element during emission by each light source. The optical properties of the sample is calculated based on the output of the light receiving element for a first light source, output of the light receiving element for a second light source, and the respective weighting coefficients. Accordingly, measurement values can be obtained which are equal to values when measurement is accomplished with a standard light source.
