The parameter coupling feature of VirtualLab Fusion enables the linking and configuration of dependence between parameters in an optical setup in a flexible way. For this purpose, the relevant parameters have to be selected and can then be used for instance as variables in mathematical formulas to calculate the values of other parameters of the system. Thus, parameter coupling allows the user to establish complex relationships between parameters of the optical system in question which will be automatically maintained. In particular, parameter coupling is very helpful if specific parameters of the optical system are intended to have a fixed relationship during an analysis or optimization.
Parameter Coupling
This example provides a step-by-step explanation of how to link two parameters of an optical system (e.g. of a grating). As a result, during the variation of a parameter the linked one gets automatically adapted according to the defined relationship or formula.
Automatized Detector Positioning
In this example, the focus (PSF) of an F-theta objective is investigated for certain angles of incidence. In order to avoid the superfluous computational effort introduced by the shift of the resulting foci with off-axis illumination, the detector position is shifted according to the main propagation direction of the light.
