Hi Onder,

Assuming this is sequential mode, maybe the stop is in front of the lenses? And the semi-diameters fixed? OpticStudio fills the stop, but when rays miss a surface they are terminated. If that’s the case, you might want to choose another surface for the aperture stop.

If that’s not the case, is this sequential or non-sequential? What is the system aperture set to, and what surface is the stop?

Best,

David

Hi David,

Thank you for your response,

This is a sequential mode, my aperture set is defined as image space F/# and my stop is adjusted as a surface at the very back side which is not seen in the picture.

I draw a dummy surface at first to see the rays incoming, and when I take out this first dummy surface the weirdness clear out.
