Re: FRED vs ZEMAX

Philip's advice is best here. I have seen people use ZEMAX for
problems that are much better handled by something like FRED and seen
people use FRED for problems that are much better handled by something
like ZEMAX.

In addition to what Philip said about how he uses ZEMAX and FRED, I
found that for doing illumination design, programs like FRED (I do not
use FRED specifically, there are others similar to FRED like ASAP,
LightTools, and TracePro) are more appropriate for the task than
ZEMAX, although there are plenty of people that use ZEMAX for
illlumination.

You might get better input if you can explain a little more about the
types of problems you are trying to solve with the software.
