Class Information
Number: 356/446
Name: Optics: measuring and testing > Of light reflection (e.g., glass) > With diffusion
Description: Subject matter wherein the light reflected from the material or sample is scattered by reason of the surface irregularities of the material or sample alone; or wherein the reflected light is a combination of the scattered light and specularly reflected light; or wherein the reflected light is scattered from particles distributed on the surface of the material.
