Our Digital Abbe Refractometer is widely used to determine the refractive index and mean dispersion of transparent liquids and solids. It is also designed for determine sugar content in aqueous solution . With the help of the thermostat it may determine the refractive index of substance for the temperatures from 10°to 50°.

Operating Principle And Theory In the Digital Abbe' refractometer the liquid sample is

light entering the refracting prism will have smaller qr

sandwiched into a thin layer between an illuminating

Thus, a detector placed on the back side of the

prism and a refracting prism. The refracting prism is

refracting prism would show a light region to the left

made of a glass with a high refractive index (e.g., 1.75)

and a dark region to the right.

and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism. A light source is projected through the illuminating prism, the bottom surface of which is ground (i.e., roughened like a ground-glass joint), so each point on this surface can be thought of as generating light rays traveling in all directions. The light traveling from point A to point B will have the largest angle of incidence (qi) and hence the largest possible angle of refraction (qr) for that sample. All other rays of

Samples with different refractive indexes will produce different angles of refraction and this will be reflected in a change in the position of the borderline between the light and dark regions. By appropriately calibrating the scale, the position of the borderline can be used to determine the refractive index of any sample. In an Digital Abbe' refractometer there is not a detector on the back of the refracting prism, and there are additional optics, but this is the essential principle.
