| Zusammenfassung: | A beam twister consists of roof reflector-mirror pair is described. The pair reflects incoming light beam and, in the meantime, rotates the beam around its propagating direction by 90 degrees. For beam array, its size-divergence product can be changed by an array of the pairs, which makes it possible to focus the beam array into small spot. If the pair is integrated into a solid piece, the device is very robust and works with wide optical spectrum and high damage threshold. |
