On September 15th 2020, Zemax released OpticStudio 20.3, and the release notes announced exiting major speed improvements for both Sequential and Non-Sequential mode.
I wanted to clarify and provide examples that highlight those speed improvements.
-Sequential mode optimization, here is a system we typically use for training, and you can see a 3x improvement (file attached ‘’optSpeedTest’’). What we have improved is the multithreading of our Damped Least Square optimization algorithm, so the speed improvement can be observed over complete optimizations, not just raytracing speed.
-In Non-Sequential raytracing through CAD objects is now faster using the new ACIS libraries.
Using the ‘’white LED phosphor.zmx’’ in the sample files, without ignoring the CAD, I get a 4x improvement.
I hope that this will prove useful.
