Spherometer Disc Type
Product Code : JA-MI-2120
The Spherometer Disc Type (SKU JA-MI-2120) measures the radius of curvature of lenses and spherical mirrors. It has a small metal frame supported on three legs at the corners of an equilateral triangle, with a fine pitch screw through the centre that forms the fourth leg. This disc type spherometer carries a pitch scale in millimetres with zero at the centre (10-0-10 mm) and a circular scale on the screw head divided into 100 parts, or 50 in some versions. JaincoLab manufactures it for school and college physics.
Specifications
The pitch scale on a metal strip at right angles to the frame reads 10-0-10 mm, and the circular scale on the screw head has 100 equal divisions (50 in some versions).

Applications of the disc type spherometer
The height of the central screw above the plane of the three legs, with the leg spacing, gives the radius of curvature of the surface.
- Radius of curvature of a convex lens in class 11 and 12 practicals
- Curvature of concave and convex mirrors
- Thickness of thin glass plates
- B.Sc physics measurement practicals
