I have been digging around to see an existing model for a retroreflector with various triples size and angles. I can’t seem to find any. I wanted to know if anyone has a handy model that doesn’t take a long time to ray trace?
Thanks!

Retroreflector Non-Sequential Model

Here are just a few ideas but let us know if that helps or not:
- We have some corner cubes models under https://support.zemax.com/hc/en-us/articles/1500005488341-How-to-model-corner-cube-retroreflectors?
- Thorlabs provide some CAD examples on their website: https://www.thorlabs.com/navigation.cfm?guide_id=2539.
- We also have a Ray Rotator object to function as a retroreflector. The Ray Rotator is an imaginary device that rotates all incident rays. For example, if you want the Ray Rotator object to behave as a retroreflector, you can first set its Material as Mirror and then set its 'Rotate Z' to 180 degrees. Now the Ray Rotator acts simply as a retroreflector to reflect and rays will propagate back along the same path as they came.
