Zemax User Manual -

Panic was a luxury Aris couldn't afford. The launch window was in fourteen hours. His team had run the simulations. The new actuator would throw the image into a coma so severe that a planet’s ocean would look like a smeared thumbprint. The only solution was to redesign the tertiary mirror's alignment—a problem of geometric optics so fiendish it would take weeks to solve.

Non-sequential mode & component types

Reading the manual from cover to cover is impractical. Instead, treat it as a dynamic reference tool using these pro-tips:

For the latest releases (e.g., 2025 R1 onwards), the manual is integrated into the Ansys Help Viewer

Keywords like "MTF," "Asphere," or "ZPL" will direct you to relevant, detailed sections. zemax user manual

Optimization strategies & operands

If you are using older builds (e.g., Zemax 12, 2009, or 2010), the manual is distributed locally. You can access it by launching the software and navigating to Help > Manual . In these versions, the document is typically a large PDF file (often exceeding 700 pages) named ZemaxManual.pdf .

Polarization and coatings

Formulas for coordinate breaks, aspheres, diffractive optics, and freeform geometries.

This is the core table where optical surfaces, materials, radii, thicknesses, and conic constants are defined. B. Sequential Modeling

The user manual includes a dedicated section for , a powerful scripting tool for automating tasks, creating custom analysis plots, or running specialized optimizations. ZPL Macros: Examples of how to automate repetitive tasks.

“We don’t have time to decipher that thing, Lena,” he said. The new actuator would throw the image into

Years later, at a conference, a young graduate student asked Aris what the most important tool on the Erebus project had been. He expected Aris to say the carbon-fiber lathe, or the cryocooler, or the 4K sensor.

A standard Zemax user manual (Version 1.1.2 or later) typically follows a logical progression from installation to advanced topics.

The official manual is typically over 2,500 pages. Navigating it without a strategy is futile. Here is the logical breakdown:

MTF, PSF, and image quality metrics

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.

Before diving into the manual’s contents, it is critical to understand the nomenclature. Originally developed by Focus Software, the platform was known as (a portmanteau of "Zernike" and "MAXimum"). In 2014, Ansys Inc. acquired the product and rebranded it as Ansys OpticStudio .
