With the minimization of optical devices, the size of lens becomes much smaller. As a crucial parameter of spherical lens, the measurement of curvature radius is valuable in small lens manufacturing. In this paper, confocal microscope method is proposed to measure curvature radius of spherical lens, especially small spherical lens. The setup of thi...

Dynamic concentricity measurement of small holes distributed in large room is valuable in assembling some big and complex optical facility. It's not feasible for the conventional measurement with portable CMM or laser tracker. A solution of dynamic concentricity measurement is put forward in this article, in which low power laser was selected as re...
