Design of Diffractive Beam Splitters for Generating a 2D Light Mark

Applications of diffractive beam splitters can be found in e.g. laser material processing, optical metrology, lighting and many more. By using the iterative Fourier transform algorithm (IFTA) in VirtualLab Fusion, customized beam splitters can be designed efficiently and flexibly for specific target patterns, like an expected light mark as in this example. Various merit functions are available for the evaluation and further optimization of the designs.
