Efficiency of multi - source simulators built on a halogen and xenon lamp

The paper presents the effectiveness of multi-source simulators built on the halogen and xenon lamp. The presented calculations have been carried out, using MATLAB 2007. These calculations compared with the efficiency of monosource simulators (built only on the halogen or xenon lamp). The final results of calculations presented in tables and graphs. It was also considered the usefulness of discussed sources of light for the construction of sun simulators.
