Abstract: A spectral device is provided with: a filter having a property of transmitting light of multiple wavelength ranges from a measurement object; a driving means to slide the filter; and a detector to detect an intensity of the light from the measurement object, the light having passed through the filter, the detector to further measure the intensity of the light multiple times sequentially while the driving means slides the filter and thereby obtain multiple pieces of measured data to be used for a calculation of spectral information.
