Radius of curvature (applications) - Wikipedia, the free encyclopedia
The distance from the center of a sphere or ellipsoid to its surface is its radius. The equivalent "surface radius" that is described by radial distances at points along the body's surface is its rad...

The proposed apparatus is accurate enough to be useful to anyone using curved optics and needing a quick way to assess the values of the radii of curvature, be it for entrance quality control or trouble shooting an apparently malfunctioning optical system.

Traceable radius of curvature measurements are critical for precision optics manufacturing. ... The translated distance is nominally the radius of curvature; however, errors in the motion of the stage add a bias to the measurement, even if the error motions are zero on average. Estimating the bias and resulting...

We measure this by the curvature (s), which is defined by ... The radius of that circle is called the radius of curvature of our curve at argument t. ... We will see that the radius of curvature, which is a length is exactly , the reciprocal of the curvature.

Circle of curvature is a circle that "fit" the curve at a point. If the curve is turning sharply, the radius of curvature is small and if the curve is turning slowly, the radius of curvature is large.
