LENS HAVING A PLURALITY OF SURFACES WITH ZONES |
摘要 |
A lens (1) comprising a plurality of optical surfaces (S1, S2) each of which is made up of an alternation of active zones (ZA1, ZA2) and separation zones (ZS1, ZS2). The active zones of one of the surfaces are situated beside the separation zones of the other surface. The shape of one at least of the optical surfaces is then adapted into the separation zones in order to augment the acute angles that are situated at the convergence of active zones and separation zones. The lens can thus be made with improved accuracy with respect to a target optical function. |
