与Clear-diameter不同，clear-diameter是指透镜的半径、与曲率半径有关的，而semi-diameter与曲率半径无...
Hi I am curious if anybody in the community knows what this means, I’ve never seen it before…. After optimizing the mechanical semi-diamter and chip zones on this surface disappeared and an asterisk appeared next to the clear semi-diameter value. I’m not sure what’s going on here...
When you use a UDA to define an aperture, you lose the ability to define details like a mechanical semi-diameter or chip zone. So, the UDA will only be able to define out to the geometry you define, which is the mechanical semi-diameter, but it will treat it like a clear aperture. ...
