Hi everyone,
I have a sag table with a couple of rows, I want to insert the corresponding aspheric terms into ZOS lens editor.
How can I achive my goal?
Any help is appreciated.

Hi Önder,
We are getting there. I’m assuming the units are mm (millimeters), since you are missing an X column in your table, I’m also assuming this profile is rotationally symmetric, and I’m guessing that at Y = 0, then Z = 0.
There are several ways you could transform this data into a surface as far as OpticStudio is concerned. If you intend to manufacture this lens, you should perhaps contact the manufacturer, and ask what they prefer.
In my opinion, you could either use this data and create a 2D rectangular grid, but if your surface is rotationally symmetric it might be the slowest option in terms of calculation time, and feed it to the Grid Sag surface. Or, and that’s probably what I would do, you could fit a polynomial (or any other type of fit) to this profile, and use the Extended Polynomial surface (or the corresponding surface that matches your fit, such as Chebyshev for example).
Does that make sense, and do you need help doing that?
Take care,
David
