This paper describes two opto‐electronic processes useful for measuring curvature radii of optical components. The two methods start from the fact that, within the geometrical optics approximation, a pencil of rays can be marked electronically and thus located during its propagation through the optical system. The two methods have proved to be useful for accurately measuring plano‐cylindrical lens curvature radius.
