Class Information
Number: 356/236
Name: Optics: measuring and testing > Photometers > Integrating spheres
Description: Subject matter including a hollow body of spherical interior and having an interior surface of highly reflecting and also diffusing material and having relatively small openings in the shell of the body to admit light for the purpose of raising the interior illumination to a level which depends only upon the amount of light entering the openings and not upon the reflection or diffusion of the incident light flux.
