摘要
A color distribution measuring optical system generates an image of an object to be measured via an imaging optical system and a color matching function filter. The color matching function filter is an optical multilayer film filter, and the angle of arrangement of the color matching function filter can be changed, with respect to an optical axis of the imaging optical system, depending on the numerical aperture of the imaging optical system by a tilt angle changing device. Various imaging optical systems can be used even when the optical multilayer filter is used.
