The body of the instrument
is fixed, with a leaning of 60 . Correct Refractive Index and Sugar Percentage
can be read directly in the field. It consists of Abbe’s Double Prisms with the
Thermostat, Compensator, Telescope Mirror, Limb, Graduated Sector, Reading Magnifier
and Radical Arm which carriers a Vernier. Abbe’s Double prisms leaves a narrow
space (about 0.1 mm) between the adjoining faces of the prisms. Compensator
consists of the Amici Prisms which serve for reading the line of Ach.
