An integrating sphere (also known as an Ulbricht sphere) is an optical component consisting of a hollow spherical cavity with its interior covered with a diffuse white reflective coating, with small holes for entrance and exit ports. Its relevant property is a uniform scattering or diffusing effect. Light rays incident on any point on the inner surface are, by multiple scattering reflections, distribute… WebApr 11, 2024 · Remember this is still a DIY sphere. I would not expect better then ~10% accuracy at the very best. Consistency is the most important thing with a standard calibrated device. Mine still reads the same (minus 3 lumens, which I expect is due to dust) 1.5 years later. So I am happy with the results. Agro (Agro) December 29, 2024, 3:47pm 51
