I wanted a tool for quickly setting up and simulating optical systems in 3D, so I built this.

It currently supports multiple source types, lenses, mirrors, gratings, and beamsplitters. I'm working on adding more component types and analyses soon, as well as realistic coatings and stock lens catalogs.

There is a free limited demo (max 3 components) available as a static x64 EXE for Windows if anyone would like to test it out.
