請(qǐng)教Zemax中Angle超過(guò)180度(超魚(yú)眼Lens)的設(shè)定方法?

最近在設(shè)計(jì)超魚(yú)眼鏡頭,view angle 超過(guò)180度,在Zemax設(shè)定中會(huì)發(fā)生角度全反射的問(wèn)題,請(qǐng)教各位先進(jìn),該如何解決呢?

Lens1: Red光為200 deg ; Green光為180度.

Lens2:Red光為200 deg ; Green光為180度;物距=infinity.

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.

What you see in your second diagram is not TIR but the result od sequential ray tracing!! : )
