Optical surface of optical device, for deflecting beam from light source to target surface, has several optical partitions for enabling distribution of predetermined light intensity of light source with respect to target surface

摘要

The optical surface (10) has several optical partitions (20-28) for enabling the distribution of predetermined light intensity of light source (Q) with respect to target surface (12). The optical partitions are geometrically and smoothly adjacent to each other. The number of optical partitions is 4-25. An independent claim is included for an optical device.
