What is the right optimization operand(s) in designing flat field objectives?
Solved
flat field and field curvature
Best answer by Mark.Nicholson
The default merit functions are your best bet. In general its not a good idea to optimize for specific aberrations as image quality will worsen. Optimize for image quality first, and increase the weights on your off-axis fields if necessary to get a flatter performance. You can also add a field flattening lens close to the image surface to provide a flat field.
