Smallest Radius Of Curvature

For optics fabrication, the smallest radius of curvature (the amount of curvature or bending present in the surface or element) is need. It can be calculated out of the asphere parameter shown in the picture below and the clear aperture. To use the calculator for off axis aspheres or axicons please change the asphere type and provide x0 and x1. These are the start end coordinates along the x-axis.
