Sorry that this title is not accurate. The TIR occurs sometimes when we recreate something from a patent or we add extra operands other than the operands generated by the field wizard.
I have been asked several times. I got this error message during my current project. So I want to share some thoughts about how to do this:
- Reduce the field/ numerical aperture to remove the TIR first
- Apply the RAID/ MXAI/MXRE/MXRI to constrain the incident angle
You can optimize the lens shape to reduce the angle
