Mark these pricks as a b and c. It consists of a central leg os which can be raised or lowered through a threaded hole v nut at the centre of the frame f. The tips of the three legs form an equilateral triangle and lie on the radius.
Parts of the spherometer.
It is used to measure either very small thickness of flat materials like glass or the radius of curvature of a spherical surface thus getting its name. A b c legs d central leg or middle screw e circular scale f screw head g linear scale or pitch scale reading for convex and concave surfaces first we want to find the pitch of the spherometer. A spherometer consists of a metallic tripod framework supported on three fixed legs of equal lengths. Measure the distance between the pricks by joining the points as to form a triangle.
