An integrating sphere (Ullbricht sphere) is a spherical cavity covered in its inner with a diffuse coating, white and highly reflective, and a light input hole and another output for attaching the measuring device.
In this way, all the light that the source emits inside is captured and its luminous flux (or radiant flux) can be measured. Other applications are the generation of a uniform light source at the optical output, or the integration of all the light that emits an external light source (in a wide cone of angles, diffuse light).
Together with our measuring equipment (photometer / radiometer, colorimeter, spectrometer) we can offer integrating spheres of different sizes and calibrated for the selected configuration (meter-fiber-sphere typically).
