A spherometer is a precision measuring instrument designed with a metallic frame that forms an equilateral triangle. This triangle is supported by three legs, with the tips of the legs lying on the radius of the triangle. The spherometer also features a central leg that can be adjusted perpendicularly. In this article, we'll guide you through the process of using a spherometer to measure the radius of curvature of a spherical surface.
