The function of an integrating sphere is to spatially integrate radiant flux. Before one can optimize a sphere design for a particular application, it is important to understand how the integrating sphere works. How light passes through the sphere begins with a discussion of diffuse reflecting surfaces. From this, the radiance of the inner surface of an integrating sphere is derived and two related sphere parameters are discussed, the sphere multiplier and the average reflectance. Finally the time constant of an integrating sphere as presented is relevant to applications involving fast pulsed or short lived radiant energy.

The flux can be measured directly or after it has interacted with a material sample. The sphere as part of a radiometer or photometer can directly measure the flux originating from lamps and lasers or the flux density produced from hemispherical illumination. Perhaps the largest application for integrating spheres is in the measurement of the total reflectance or transmittance from diffuse or scattering materials. An alternative application utilizes the port opening of an internally illuminated integrating sphere as a large area source that features uniform radiance. Theses sources can be used to calibrate electronic imaging devices and systems or simply as uniform back illuminators.
