The discussion centers on the search for freeware capable of simulating a system with three mirrors, a laser, and a detector. Users noted that while many software options exist for lenses, fewer are available for mirrors. The most recommended software for this purpose is Oslo, which is a comprehensive tool for optical design and can handle both lenses and mirrors effectively. Advanced packages are necessary for accurate laser modeling, but basic simulations can be achieved with simpler tools.
PREREQUISITESOptical engineers, physics students, hobbyists interested in optical simulations, and anyone looking to model complex light systems with mirrors and lasers.
