I just started using Atmos for apo lens design, and I especially like the optimization tool. But I have a serious problem with the aperture stop. When I start a new design, the aperture stop is automatically set to 1mm, and if I change it, it has no effect. Then I can also click on the aperture stop and answer ‘no’ to the question of whether I want an aperture stop on that line, but there is no change.

How can I solve this strange problem?

Thank you very much for help!

You have to specify entrance pupil aperture radius (semi diameter)
