A spherometer is a device used primarily for measuring the curvature of objects such as lenses and curved mirrors. For further information about spherometers, see object MA.315739. This spherometer is very small, measuring just over 6 centimeters across. It has both a vertical and horizontal scale. It comes in a small cylindrical box, reminiscent of a hat box, marked Germany but no maker is evident.
