PURPOSE:To store and process spectrum in a short time by taking in data through scanning only of the data required in relation to an optical filter of a rotary disc. CONSTITUTION:A white ray emitted from a lamp 1 passes through the optical filter disc 2 and is absorbed by a measuring sample 3 and then falls on a spectrometer 4. The spectrometer 4 is usually a spectral graph and a detector 5 is set at the imaging surface thereof. While the optical filter disc 2 makes one rotation at least, scanning of the entire region of wave-length is completed, and, by scanning only the area of wave-length corresponding to each optical filter, the time for measurement can be reduced sharply. |
