  I am trying to collimate this lens so I can turn it into a CAD model and 3D print at the nanoscal. How do I use the merit functions and optimization to do this? I am not sure which operands to use and how to use them.

  Hi Hazal,
  Thank you for reaching out to us! I think for this case you should use the angular radius citerion on Default merit function operands and drive it to zero.
