I would like to trace rays into this object and let them TIR around the inside.
The attached gives an idea but is not correct. I have used the swept object to generate the annulus.
It has in outside radius of 4mm and an inside radius radius of 2mm, concentric surfaces, Germanium.
I don’t know how to get rays in or out.
I would like the source rays to be collimated, or converging, or diverging, or astigmatic.
Can anybody help!
I know that I don’t know how to do the entrance or exit surfaces properly.
