Abstract

PURPOSE:To separately meter the reflected or transmitted component and the fluorescent component at a point of a sample by separating the light, which is relflected or transmitted at the sample, into that having the same or different wavelength as or from the incident light to separately store the received output when the incident wavelength from a light source is changed. CONSTITUTION:The light from a white light source 1 is converted through spectroscopic means 2 into a monochromatic light, and a reference white plate 3 having its absolute spectroscopic reflectivity known is diffused and illuminated by a integrating bulb 5. The reflected light is guided by a lens 6 into a spectrometer incident slit 7 so that it may be emanated by a diffractive grating 8 having a concave side to the position of an image sensor 9 corresponding to the incident wavelength. Then, the reference white plate 3 is replaced by a sample 4 containing a fluorescent light, and similar measurements are accomplished so that the signals from the sensor 9 in the same wavelength as the incident light are stored in the first memory 11, whereas the incident light are stored in the first memory 11, whereas the signals from the sensor having different wavelength are stored in the memory 12. The illuminating light is scanned with the spectroscopic means so that the signals at respective wavelengthes are summed at the memories 11 and 12. Then, it is possible to separately display the spectroscopic reflection and fluorescent lights in first and second display units 13 and 14.
