| The body of the instrument is fixed having a leaning of 600, correct refractive index and sugar percentage can be read directly in the field. It consist of a abbe double prism compensaor, telescope mirror limb, graduated sector, reading magnifier and a radial arm which carries a vernier. Abbe's double prisms leaves a narrow space(about 0.1 mm.) between the adjoining faces of prism and compensator consists of the amici prisms which serves for rendering the line of achromatic separation.
