| 摘要 |
A device for optical beam homogenization, comprising two essentially opposite-lying, optionally functional limiting surfaces which can be used as an incident surface (7) and an exit surface (8) for beams of light (2,5). The incident surface (7) and the exit surface (8) have lens-type structures at least in sections. The structures formed on the incident surface (7) and exit surface (8) are embodied in the form of alternately arranged convex sections (9;11) and convex sections (9,11). The transitions between the convex sections (9,11) and the concave sections (10, 12) are relatively smooth. The invention also relates to an optical beam homogenization arrangement comprising a device (3) of the above-mentioned variety. |
