WebBeam shaping using DOEs Diffractive beam shapers are phase elements that transform the Gaussian input beam into uniform spots with sharp edges at a specific working dis-tance. Each beam shaper is designed for specific use with a unique set of optical system parameters: wavelength, input beam size, working distance, and output spot size. WebUnique to PowerPhotonic, we create a diffuser surface from a multitude of randomised angled facets; so called Pseudo Random Intensity Mapping Elements (PRIME). The effect of the PRIME surface is to add a Flat Top statistical distribution of divergence angles to the input beam. The full width. angle of this distribution is the nominal design ...

Before becoming a professor in Theoretical optics in 2007 he was researcher and senior assistant in University of Joensuu and a Project manager in Heptagon Oy. His long term scientific visits to foreign universities include 2 months stay in … WebRefractive beam shapers allow for uniform irradiance distribution and flat phase fronts. Figure 3: Example of refractive beam shaping employing field mapping 2. However, focusing a flat top beam through a lens will not result in a flat top profile at the final focused spot, as the lens will affect the beam profile.
