principle

By measuring the intensity and Light spectrum characteristics of the reflected light on the surface of the object, the integrating sphere is used to collect the diffuse reflected light and convert it into an electrical signal, so as to calculate the whiteness value of the object.

function

Measurement of the whiteness value of the surface of the object, by detecting the intensity and characteristics of the reflected light, evaluate the whiteness level of the material.
