Abstract
A spectroradiometer is calibrated by a calibration source including a plurality of monochromatic sources for emitting monochromatic rays having different wavelengths from each other, respectively; a reference light emitter for emitting monochromatic reference light by receiving the monochromatic rays emitted from the monochromatic sources; a reference sensor for measuring a reference intensity of the monochromatic reference light emitted from the reference light emitter; and a controller for controlling the emission of the monochromatic rays by the monochromatic sources, and the measurement of the reference intensity of the monochromatic reference light by the reference sensor.
