This part of IEC 61300 series is intended to characterize the encircled angular flux of measurement multimode fibre light sources, in which most of the modes are excited.
Encircled angular flux (EAF) is the fraction of the total optical power radiating from a multimode optical fibre's core within a certain solid angle. The EAF is being measured as a function of the numerical aperture full angle. The basic approach is to collect, for every measurement, two dimentional far field data using a calibrated camera and to convert them mathematically into encircled angular flus.
