Spherometer to Measure Curvature of a Round Surface

Description

* Vertical scale range is -10 to +10mm.* Geometry is 3 points and one center screw, points are 40mm apart.* Graduation resolution is 0.01mm.* Used to determine the radius of curvature of a round/spherical surface.* Precise in the calibration and correlation of the vertical and horizontal scales set.* Spherometer is for measuring the curvature of a round surface. Typically this is used for measuring lenses in physics labs to determine focal length and other geometrical optic measurements. This tool will measure the curvature of nearly any surface that fits between the 3 points (40mm apart). It is a precise apparatus with a vertical measuring graduation of 0.01mm.
