INTRODUCTION
  The polarimeter is an instrument used for determining the Optical Rotation of substances.In this way,the concentration,content ,purity,ect of certain substances can be found out.Therefore,the polarimeter has become one of the most useful instruments in laboratories of sugar industry,pharmaceutical industry,oil refining,foodstuff industry,chemical industry,universities and scientific research field.
