Released: February 16th, 2021

OpticStudio 21.1.1 contains the following fixes and enhancements.

Performance & Stability

• Gradient 5 –  Detection of the ray-surface intercept on a Gradient 5 surface is now faster and more robust, in particular for large angles of incidence.
• CAD – Improved the detection of co-located geometries and glue distances when using ACIS libraries.

Bugs

• Zemax Black Box –  Fixed an issue with ray tracing and paraxial image height calculations for Black Boxes when apertures defined in the Black Box may have caused vignetting.
• Volume Holograms – Corrected behavior of ray tracing with volume holograms. This includes curvilinear holograms and holograms in some mirror space configurations.
• Tolerancing – Fixed a bug where the Yield plot could be incorrectly reversed when a MTF option was selected as the tolerancing criterion.
