COLOR DISTRIBUTION MEASURING OPTICAL SYSTEM, COLOR DISTRIBUTION MEASURING DEVICE, AND COLOR DISTRIBUTION MEASURING METHOD

摘要

color distribution measuring optical system (21, 32, 33) is an imaging optical system (21 ) and the orange filter and the function generating an image of the measurement object through 32. The color matching functions filter 32 and an optical multilayer film filter, disposed angle of the color matching function filter 32, the opening of the imaging optical system 21 with respect to the optical axis Ox of the imaging optical system 21 by the angle change unit 322 tilt It may change according to the number. While using the optical multilayer filter is a variety of imaging optical systems enable.
