When carrying out FIDA measurement, the eccentric rotation mirror 40 is rotated to optically scan a condensing spot of a laser beam in a generally elliptical shape at a focus position in the solution held in the sample container. When carrying out FCS measurement, a mirror surface of the eccentric rotation mirror is fixed in an orientation in which light passing through an optical axis passes through the object lens along the optical axis, and confocal illumination is carried out in the solution by the light passing through the optical axis.

    Abstract: PROBLEM TO BE SOLVED: To calibrate highly accurately an observed wavelength by excluding an effect of the whole non-flatness of light emission intensity ripple included in emitted light from a light emitting diode or a light intensity distribution of the light emitting diode.
    SOLUTION: The method comprises processes for: allowing reference light in a prescribed wavelength band emitted from the light emitting diode to pass a gas absorbing cell for absorbing light having a specific wavelength, and determining an observation spectrum of transmitted light after passing; determining a moving averaging observation spectrum by applying moving averaging processing to the observation spectrum; determining a corrected observation spectrum by taking the ratio between the moving averaging observation spectrum and the observation spectrum; and calibrating the observed wavelength based on the difference between an absorbed wavelength by the gas absorbing cell and a known specific wavelength in the corrected observation spectrum.

    Abstract: PURPOSE:To perform spectral photometry in a short time with sufficient measuring accuracy being maintained, by modulating the emissions from (n) pieces of light sources by different frequencies of (n-1), thereby performing the spectral photometry of the emissions at the same time. CONSTITUTION:Light beams emitted from first and second light sources 1 and 2 having different color temperatures are guided to a double monochrometer 7 through rotary sectors 3 and 4 having different frequencies, a BaSO4 diffusing plate 5, and a mirror 6. The light beams, whose spectrums are divided by the monochrometer 7, which is set at a specified wavelength, are inputted to a photoelectric multiplier tube 8. Its output signals pass through first and second bandpass filters 10 and 12 corresponding to the frequencies of the rotary sectors 3 and 4 and separated into several signal components, which are in turn detected by a synchronous detecting circuit 11 and a detecting circuit 13. By sequentially moving and setting the wavelength of the monochrometer 7, the distribution of the spectral emissions of the visual parts from the two light sources 1 and 2 can be simultaneously obtained. Thus the spectral photometry can be performed in a short time, with sufficient measuring accuracy being maintained.
