Aperture Stop


Forum|alt.badge.img

Hello everyone,


I want to see the stop as a usual form but I can not for the time being. The stop is highlighted as big orange circle on the picture below.


I simply want to limit the light entering through stop; however, this filtering out function doesn't seem below, also the mechanical appearance of the aperture is somewhat unexpected to me.


any help on clarifying this is appreciated,

Hello Onder,


I don't  understand the situation. Because field rays are converging this appears to be the rear elements of a larger system. If you intend the orange surface to be the aperture stop, then you need to fix its semi-diameter, make it the stop, and set the system aperture type to float by stop size. OpticStudio will then fill the stop with rays. If this does not solve the problem, perhaps you could attach the design as a ZAR.


Kind regards,


David
