Abstract: A lens (1) includes 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.
Abstract translation: 透镜（1）包括多个光学表面（S1，S2），每个光学表面由活动区域（ZA1，ZA2）和分离区域（ZS1，ZS2）的交替组成。 其中一个表面的活动区位于另一个表面的分离区旁边。 至少一个光学表面的形状然后被适应到分离区域中，以便增加位于活动区和分离区的会聚处的锐角。 因此，可以相对于目标光学功能提高透镜的精度。
