24.1 Release Notes

January 11th, 2024

1 Tools, Features, and Capabilities

1.1 Offline legacy license activation (All Editions)

Activate, update, and transfer all your licenses offline.

A new Zemax License Manager release is included with OpticStudio or available as a separate download. This release adds an offline section with a built-in offline softkey license activation and license transfer process.


This means these operations no longer need to be done via a separate application. Since we are now issuing Ansys licenses, this also prepares Zemax legacy applications for the future discontinuation of the legacy online license servers.


2 Libraries and Catalogs

2.1 Catalog Updates (All Editions)

Bug Fixes

  • Diffraction Encircled Energy - Fixed an issue where incorrect reference coordinates were reported in Diffraction Encircled Energy if “Show Diffraction Limit” was not selected.
  • Parasolid CAD files - Fixed an issue where rays were not included in exported CAD files when using the Parasolid libraries.
  • Extended Diffraction Image Analysis - Fixed an issue for Extended Diffraction Image Analysis to improve results when paraxial and real image height calculations are significantly different.
  • Extended Diffraction Image Analysis - Fixed an issue in Extended Diffraction Image Analysis where the vertical image direction was inverted.
  • Exporting CAD files using Parasolid - Fixed a crash when exporting a CAD file using Parasolid when the system dimensions exceeded the maximum limits allowed by the Parasolid modelling kernel.
  • User Defined Surface - Fixed an issue with the files us_polarization2.cpp and us_polarization2.dll to correctly pass back reflection and transmission values when method 0 is selected.
  • Tolerance Operands - Fixed an issue where tolerance operands TRLX, TRLY, TRLR, TARX, TARY, and TARR could produce incorrect perturbation values of zero for non-axially symmetric systems.
  • Convert to NSC Group - Fixed an issue where an off-axis mirror with a floating aperture was not correctly converted during a sequential to non-sequential conversion.
  • Convert to NSC Group - Fixed an issue where a coating on a sequential mirror was applied to the wrong face after a sequential to non-sequential conversion
  • Black Box - Fixed multiple issues where certain systems with Black Box surfaces would not successfully export a Speos reduced order model.
  • Multiphysics Data Loader - Fixed a crash that could happen when loading STAR data for systems with Robust Ray Aiming turned on.
  • Convert ZRD or ZBF to TSV - Fixed an issue with the Convert ZRD or ZBF to TSV tool where it would fail to generate an output file when the ZRD file is too large.
  • SSAG MFE Operand - This fix enables calculation of the sag with no lateral limitations for cases where surface aperture is set to “None” or “Floating”. Typically, SSAG returns zero outside of the surface aperture.


4 Announcement

Zemax OpticStudio 24.1 is the last release of our legacy product (under legacy licensing). After 24.1, all OpticStudio releases will only be available as Ansys Zemax OpticStudio. To continue to have access to the latest features, please contact to discuss migrating your legacy license to Ansys Zemax OpticStudio.
