Ring Array of LED sources do not refract on lense surfaces

Hello, I am trying to simulate a LED array arranged in a circle with a collimation towards the center of the ring. For some reason, the source rays are interacting with a mirror I arranged in the same way but not with both collimation optics. Why are the lenses not considered in the simulation?

Best, Thomas.

Hi Thomas,

It is because the source volume is inside the LED body array ring, but not designated as such. So OpticStudio gets confused about ray-face intersections. The Inside Of column for object 8 should read 6 for the LED body array. Object 7 (the die) should also be inside 6.

Thank you David! This solved the issue!
