Zemax user manual serves as the primary technical resource for Optical and Illumination design engineers. It provides the foundational knowledge required to navigate OpticStudio, the industry-standard software for designing lenses, imaging systems, and lighting architectures. This section explains how to define surfaces, set

This section explains how to define surfaces, set apertures, and apply glass materials from the Global Glass Catalogs . TRAC: Transverse Ray Aberration.

Perhaps the most critical chapter in any Zemax user manual is the one dedicated to optimization. OpticStudio uses a "Damped Least Squares" (DLS) algorithm to minimize a Merit Function. The manual lists hundreds of "Optimization Operands"—short codes that represent physical constraints or performance targets. Common operands explained include: EFFL: Effective Focal Length. TOTR: Total Track Length. TRAC: Transverse Ray Aberration.
