A handy rule of thumb is that for most real integrating spheres (0.94 < p < 0.99; 0.02 < f < 0.05), the sphere multiplier is in the range of 10 to 30.

PHOTOMETRIC TEST SYSTEM to measure electrical, luminous and color co-ordinate values, color temperature and color rendering index of LED lamps consisting of Photometric Integrator and Photometric Control as per IS: 16106: 2012,16102(Part 2) : … WebLet us explain. The “perfect” integrating sphere creates a uniform luminance distribution at all points on the sphere surface. Therefore, the small proportion of light which the detector “sees” is a known percentage of the whole. For 4pi flux measurements, you calibrate the sphere by placing a near-isotropic standard lamp in the centre.
