Product Description

This spherometer measures the radius of curvature of round or spherical surfaces using a three-point geometry with legs 40mm apart and one center screw. The vertical scale ranges from -10 to +10mm with 0.01mm graduation resolution. By calibrating the relationship between vertical and horizontal scales, students can calculate the radius of curvature of lenses, mirrors, and other curved surfaces. This instrument reinforces measurement precision and geometric principles. Suitable for physics classrooms.
