OPTICAL LENS INCLUDING OFF-AXIS AND ASPHERIC SURFACE

摘要

PURPOSE: a kind of optical lens, including off-axis aspheric surface manufacture be provided to the radius of curvature of different geographical radius of curvature more positive region and above-mentioned peripheral region, pass through and form one or more center more positive region concave surface or convex surfaces. ;CONSTITUTION: one concave and convex surface optical frames includes off-axis aspheric surface domain. A kind of more positive region 5-1 system forms the optical lens of concave surface and convex surface. Focal length corrects peripheral region of the zone time than focal length. Radius of curvature more positive region form differently the peripheral region with radius of curvature. The optical lens by center and optical axis that off-axis aspheric surface domain is a separately formed. Two curved surface (C1 has two straight dashed line C2) centerline parallel optical axises. ;The 2012 of copyright KIPO submissions
