Integrating spheres are used for a variety of optical, photometric or radiometric measurements. They are used to measure the total light radiated in all directions from a lamp. An integrating sphere can be used to create a light source with apparent intensity uniform over all positions within its circular aperture, and … See more 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 … See more For a sphere with radius r, reflection coefficient ρ, and source flux Φ, the initial reflected irradiance is equal to: $${\displaystyle E=\rho {\frac {\Phi }{4\pi r^{2}}}\,}$$ See more The theory of the integrating sphere assumes a uniform inside surface with diffuse reflectivity approaching 100%. Openings where … See more • Lambert's cosine law See more The theory of integrating spheres is based on these assumptions: • Light hitting the sides of the sphere is scattered in a diffuse way i.e. Lambertian reflectance • Only light that has been diffused in the sphere hits the ports or detectors used for … See more The optical properties of the lining of the sphere greatly affect its accuracy. Different coatings must be used at visible, infrared and ultraviolet wavelengths.
