WebIntegrating spheres are effective in causing a light beam (measurement light) entering the sphere to scatter uniformly. Integrating spheres have a hole (aperture) at the position irradiated by the measurement light. When measuring the measurement light which passes through the sample and enters the sphere, the sample is placed at this aperture. WebApr 10, 2024 · Section 3 of appendix V1 specifies that the use of a goniophotometer is not allowed, which subsequently leaves manufacturers with only the option of using an integrating sphere.
