Ray optics - ray tracing - simulator list

I want to simulate 3D structure (lens and mirror) effects on (optical) rays. Searching the forum I found ray-tracing simulators:

1. Lambda Research, TracePRO and OSLO products (http://www.lambdares.com)

2. Optical Research Associates, Code V and LightTools products (http://www.opticalres.com)

3. Breault Research, ASAP (http://www.breault.com)

What are other ray-tracing software available?

Thanks!

As known as I, the SILVACO TCAD can help you .
