Abstract: The opthalmic lens (102) is carried on a support (103) with spikes (106). Light arrives at the lens via two trajectories (112,113) from alternately switched light sources (S1,S2) using a semi-reflecting mirror and a Hartmann matrix mask (139) in one light path (112). An analytical unit (110) uses a matrix sensor or camera to determine lens characteristics and engravings respectively from the two trajectories
