I am using Optics Studio to evaluate some FEA data of an optical component (without the STAR package). I have the deformed surfaces as grid sag surfaces and am loading them in as .dat files and setup a “gradient 4” surfaces with fitted polynomial coefficients.
Is this the correct way to set up this problem? I am concerned that the grid sag surface has no thickness or material and want to be sure the model is applying the grid sag to the surfaces of my Gradient 4. I have read in the documents that dummy surfaces may be needed between these types of surfaces but when entered they make no difference. I have this set up as a multi configuration such that Flat surfaces can replace the grid sags and when toggled I do see that a change in the system performance so I know the grid sags are doing something.
Would love some feedback on this setup, thanks for the help
