Our Abbe Refractometer is broadly 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°.
In the Abbe' refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a
refracting prism. The refracting prism is made of a glass with a high refractive index (e.g., 1.75) 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 frequency (qi) and hence the largest possible angle of refraction (qr) for that sample. All
other rays of light entering the refracting prism will have smaller qr Thus, a detector placed
on the back side of the refracting prism would show a light region to the left and a dark
region to the right.
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
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.
