Advanced Configuration of Slanted Gratings
Abstract
VirtualLab Fusion can be used to analyze arbitrary types of gratings. Due to the raising importance of gratings which exhibit slanted structures within complex optical setups also slanted gratings are available. The slanted grating is realized by a special optical medium, where the geometry can be defined, versatilely. Moreover, several advanced specification options are available, e.g. adding a full and partially coating layer.
In this tutorial the available options for configuration are explained and their influence on the geometry of the grating are discussed.
