This is the most critical starting point. It defines how Zemax handles coordinate systems (Local vs. Global), field of view (FOV) , and wavelength units.

The Ansys Zemax OpticStudio user guide acts as a critical resource for optical engineers, bridging theoretical physics with practical design through structured workflows, analysis tools, and manufacturability assessments. The manual covers essential functions, including sequential modeling for imaging, non-sequential analysis for illumination, and optimization techniques for high-performance design.
