請教Zemax中Angle超過180度(超魚眼Lens)的設定方法?

最近在設計超魚眼鏡頭,view angle 超過180度,在Zemax設定中會發生角度全反射的問題,請教各位先進,該如何解決呢? HLk/C[`u,

create a dummy surface before the first lens surface and assign it a radius similar to the radius of the first lens surface and you should ge the rays from 100 half field of view display properly. i think you system design is a bit similar to  the example file, Wide angle lens 200 degree field.zmx in ZEMAX. If so I think there is a dummy surface already. Just change radius of the dummy surface shall put you right. I |BLAm6j  
)Q9J,  
What you see in your second diagram is not TIR but the result od sequential ray tracing!! : )
