Spherometer
01
a measuring tool used to determine the roundness of a curved surface
Example
The spherometer is an important instrument for testing the geometry and sphericalness of balls, bearings and other spherical components.
Opticians check the curve of contact lenses with a spherometer to ensure the proper prescription sphere is matched.
To pass inspection, the ball bearings needed a spherometer reading within tight tolerances for its spherical shape and diameter.
