Understanding Optical Specifications Edmund Optics

Knowing the value of the radius of curvature allows one to determine the optical path length of rays passing through the lens or mirror, but it also plays a large role in determining the power of the surface. Manufacturing tolerances for radius of curvature are typically /-0.5, but can be as low as /-0.1% in precision applications or /-0.01% for extremely high quality needs.
