An experimental series of four multichannel optical emission spectrometers developed and manufactured by the Vinca Institute has been described. The spectrometers, designed to satisfy users requirements, are intended for monitoring composition of aluminum alloys, carbon- and high-alloyed steels, raw materials and final products in glass industry. All spectrometers offer simultaneous determination for large numbers of elements and very rapid analysis time. The spectrometers components are mainly made by domestic manufacturers: imported components (diffraction gratings, photomultipliers, electronic components) amounted to less then 20% of total price.Conference on Applied Physics in Serbia, May 27-29, 2002, Belgrade, Yugoslavi
