Integrating Spheres

Instrument Systems Optische Messtechnik GmbH (Optronik)

Determination of radiant power or luminous flux from light sources with the aid of integrating spheres is one of the most important procedures in photometry. Designed as a hollow sphere whose inner surface is coated with a diffusely reflecting material, the integrating sphere ensures complete integration and mixing of light radiation. This is then output on a detector port for measurement.
