you might need to tweak the surface semi-diameter/radius a bit to make rays traceable towards the image plane. your calculation based on PW method is an approximation I would assume, so make a little change to start with for few cycles of optimization then you should be able to get around the problem.

Thanks for your anwser! But new problem come up.I have choosen "Afocal image space",但出射光并不平行，反而匯聚到一點(diǎn)，這是為什么呢？ 5)T{iPU%X

Once you do so, make use of Default Merit Function and select Angular Radius option. Read a bit more from the user manual about this option would be helpful!

Sorry, forget about checking the Afocal Image Space. You did so already! My apologies!
