METHOD OF MEASURING HAZE AND APPARATUS THEREOF

摘要

A method of measuring haze and an apparatus thereof are provided to quantitatively measure the haze regardless of shapes of the sample by placing the null lens between the sample and the integrated sphere and preventing the light from being refracted. An apparatus for measuring haze is composed of a light source(10) generating the light; a sample(20) in which the light from the light source is permeated; an integrated sphere(30) for detecting the light permeated through the sample and measuring the haze; and a null lens(50) placed between the sample and the integrated sphere to change the light projected to the integrated sphere through the sample into the horizontal light. The integrated sphere has a first opening(30a), a second opening(30b), a third opening(30c), a first sensor(40a) installed at the second opening, and a second sensor(40b) mounted at the third opening.
