Abstract

PURPOSE:To make it possible to take measurement easily with high precision by extracting a spectral component with maximum spectral energy within a measured- wavelength range, by increasing the energy within a measured-wavelength range, by increasing the energy of this spectral component up to the maximum mearuement level, and then by measuring the spectral energy distribution of sample light. CONSTITUTION:The control operation of control circuit 25 is fixed by the setting command of control panel 24 and preliminary measuring operation is performed firstly. When a scan within a measured-wavelength range ends, the maximum measurement data and its wavelength data within the measured-wavelength range are set in BCD registers 43 and 44. In this state, a gain adjustment of a spectral component of wavelength with the maximum spectral energy is made by variable gain amplifier 31. Thus, a gain at the maximum spectral energy point is set and then the measurement of the spectral energy distribution of radiation light (sample light) of light source 21 starts.
