PROBLEM TO BE SOLVED: To provide diffusion haze measuring method and measuring device in which a value representing a ratio of diffusion transmission light at an arbitrary angle in all light ray transmitted light is determined as a diffusion haze value, a diffusion haze value of a specimen can be measured, and a distribution of the diffusion transmission light for each angle can be examined.SOLUTION: Light beams from a light source are made into a parallel luminous flux to be radiated on a specimen, and an optical receiver is moved around an intersection of a radiation plane of the radiated luminous flux and an optical axis so that it takes an arbitrary angle with respect to the optical axis, whereby diffusion transmission light for each angle is measured. |
