    Abstract: PROBLEM TO BE SOLVED: To provide a calibration system for a spectral luminance meter which allows a user to calibrate wavelength and sensitivity of the spectral luminance meter. SOLUTION: A calibration light source 100 emits an emission line having a predetermined wavelength, and a spectral luminance meter to be calibrated measures the emission line output from the calibration light source 100. When the spectral luminance meter 200 to be calibrated measures the emission line output from the calibration light source 100, a system control part 300 estimates a wavelength of the output emission line based on the output difference from an acceptance part 205 at a plurality of measuring wavelengths adjust to the wavelength of the emission line. Calibration of wavelength of the spectral luminance meter 200 to be calibrated is performed by estimating the amount of change in the wavelength based on the difference between the estimated wavelength of the output emission line and the predetermined wavelength of the emission line.

    Abstract: PURPOSE:To improve the accuracy of measurement by providing an evaporating part for heat pipes near a light source lamp, and quickly conducting the heat of the light source to the outside thereby stabilizing the quantity of irradiation light. CONSTITUTION:Working fluid 11 such as water, ammonia, methanol, ''Dowtherm A '' is put in a metallic pipe 10 of copper, aluminum, stainless steel or the like, and the inside of the pipe is evacuated and sealed, whereby a heat pipe 14 is formed. If the plural heat pipes 14 are put near a light source lamp 6 and an evaporating part 12 is heated, the working fluid 11 deprives of evaporating heat and evaporates. The heat of evaporation is dissipated in a condensing part 13 to the outside of a photometer cover 1. Since the circumferential part of the lamp 6 is effectively cooled without using any fan, the stable quantity of light is emitted. The light transmits through a flow cell 2 sucking up a sample soln. 5, is divided to respective wavelengths by grating 3, are photoelectrically converted by a detector 4, the outputs whereof are recorded in a recorder 16 via an amplifier 15. Thereby, the stable light source is formed by the simple construction, and the accuracy of measurement is improved.
