Anotace	In the present days light emitting diodes1 (LED) based light sources become very common in most areas of life2 and scientific applications3. Due to the nature characteristic of the LED’s, angular and spectral distribution of the emitted light must be improved for specific purposes of light source4. It could be done by standard bulk optics, reflective and refractive, or in modern way by integrating planar diffractive structures. Measuring system of spatial distribution of illumination was developed, which could be used in general but with advantage mainly for improved progressive diffraction optics components. The measurement system consists of three main parts. The first one is rigid optical bench with goniometric light source holder driven by stepper motor, which operates in three degrees of freedom. The source holder has ability to correct thickness of the light source with respect to the plane of the radiation. Maximal size of the light source is 500 by 500 mm and maximal length between the source and detector part is over 3 meters. The second detection part includes fiber spectrometer, photopic photodiode and elevation laser. Latter ensures correct repeatable setting of the light source. The third part - control and acquisition hardware is crucial for proper measurement of spectral and intensity data sets. The whole system is driven by custom software, which is able to generate most types of output reports, charts and file formats.
