Elliptical lens designs and direct cut cylinder engraving technology

摘要

In the lenticular optical lens plastic/polymer processing industry today, the current old method of supplying lenticular/optical extruding cylinders consists of applying a soft copper base plating onto a steel green-based cylinder surface, which is then diamond turned and engraved. After the lenticular engraving, post chrome thin-flash plating is applied on top of the copper engraved plating, to help protect the soft copper finish underneath.
