About This Product
A spherometer gives students a hands-on way to find the radius of curvature of a spherical lens during optics practicals in school and college labs. The three pointed legs rest on the surface while the central screw is turned, and dividing the 1 mm pitch by the 100 divisions on the brass disc shows clearly where the 0.01 mm least count comes from.
