Abstract
In this paper, we present the near-field goniophotometer setup recently installed at PTB for the photometric characterization of solid-state light sources, e.g. LEDs, under near-field conditions. Moreover, as a validation of the near-field goniophotometric measurements, the luminous intensity distribution of two LEDs determined by near-field measurements is also presented and compared with those carried out separately under far-field conditions using a photometer.
