PROBLEM TO BE SOLVED: To calibrate a wavelength and sensitivity for a spectral luminance meter, which is substantially calibrated only in a factory of a maker side, a service point or the like in the past, also in a user side. SOLUTION: This reference light source 1 for the calibration is provided with an integrating sphere 11, a control processing part 12, a monitoring sensor 14, and a laser unit provided with a plurality of semiconductor lasers for generating a plurality of single wavelength reference beams or the like. The control processing part 12 lights the plurality of semiconductor lasers on sequentially, and controls an operation for monitoring the intensities of single wavelength reference beams emitted from an output opening 11a after reflected multiply by the integrating sphere 11. A photoreception part of this spectral luminance meter 4 serving as a calibration object is oriented in the output opening 11a, and operations for the reference light source 1 and the spectral luminance meter 4 are controlled by a PC 5 for control.
