"WebDetails. A spherometer is a tool used to measure spherical curvatures. They work great for measuring the radius of curvature (ROC) of your mirror as you progress through the grinding process, allowing you to determine if your ROC is getting longer or shorter. You can also use one to measure the radius of curvature of an unknown surface. " - Spherometer art
