Speckle reduction, laser power up to 50W RGB

Description

A never-ending story. Some applications like it, some not. The laser coherence and the consequent speckle. Although there is no technique yet that suppresses the speckle completely, we can at least reduce them significantly. Several techniques exists, but the one we like mostly is resulting in a square-shaped, homogeneous, low power lost, low divergence one. Has been tested with up to 50 W RGB laser source till now. An ideal solution for DLP imaging applications.
