Hi everyone, I am trying to design a dispersive system which requires that the image points of certain wavelengths at certain field positions coincide on a surface, i.e. are focussed on the same spot.
To be more precise: If have 3 field positions (in the plane of dispersion) and 3 wavelengths. In the system, which is de facto a mirrored spectrometer, 400 nm at field 2, 550 nm at field 1 and 700 nm at field 3 must coincide on the image plane.
How can I include this requirement in the optimization function?
I couldn’t find any solutions here or optimization parameters in the help screen.
