International Science and Technology Journal of Namibia, 4, 36-40.20267673http://hdl.handle.net/11070/1413A new yet very inexpensive refrectometer for the determination of refractive index and impurity in liquids at instant has been proposed. This refrectometer requires a high resolution grating, a low power laser and a position detector. The position detector analyses and determines the impurity in a liquid directly based on its refractive index. The use of a plane mirror enhances the accuracy of the refractive indices as the measurements of required parameters are greatly increased.enRefractometerDiffractionPosition detectorRefractive indicesArticle
