Discover COPHASAL, a software solution designed for the advanced design and analysis of optical systems through ray tracing. The introductory version provides a robust command-line interface powered by the Lua programming language.
To begin, download and unpack the provided folder. The executable, cophasal.exe, will initiate the software,
and the detailed user manual, manual.pdf, can be accessed using the help() command. COPHASAL has
been tested on x86-based Windows 11 PCs and should function correctly on similar systems. A Chromium-based
browser is currently required.
COPHASAL is freely available for non-commercial and trial purposes. For commercial licensing, please contact us (cophasal_support@xloptix.com). Both licenses offer the full set of functionality.
