Discussion:

A Spherometer is defined as an instrument for measuring the curvature of a surface. The Spherometer is a device use in measuring the radius of curvature of a spherical surface. For an example, it can be used to measure the thickness of a microscope slide or the depth of depression in a slide. Even the curvature of a ball can be measured using a Spherometer.

The Spherometer consists of a micrometer screw threaded into a small tripod with a vertical scale fastened to it. The head of the screw has a graduated disk used to measure fractional turns of the screw. The vertical scale is used to measure the height or depth of the curvature of the surface.

The vertical scale divisions are on 1 mm, which is the pitch of the threads of the screw. The head of the screw is graduated into 100 divisions.

This Spherometer is an Cenco Instrument.
