Changelog
Changelog v26.10
NEW: Major improvement to Tolerance Analysis: Monte Carlo and Sensitivity analyses now return a fully featured database instead of a simple report. Data can be filtered and sorted by compensator values, individual merit function constraints or goals, and much more.
NEW: Elements in the Optical Design Editor can now be positioned relative to any other element or surface.
NEW: Aspherization Wizard to find the best surface on which to introduce an asphere into a lens design. Supports standard, QCon, and QBfs aspheres.
NEW: Multiconfiguration tolerances can now be defined as relative values in addition to absolute values.
NEW: Chebyshev polynomial surface form.
NEW: Aperture solves to align the center with the chief ray.
NEW: Effective focal length and cardinal plane optimization goals for single lenses and subassemblies.
NEW: Optimization goal to optimize for tolerance sensitivity.
NEW: The crystal axis of birefringent materials is now visualized in the 3D view.
NEW: New methods in the MATLAB toolbox and Python module to add lenses and surfaces to a design.
NEW: New methods in the MATLAB toolbox and Python module to edit common parameters more quickly, such as radii, materials, and thicknesses/air spaces.
NEW: Option to export video frames as PNG files.
FIX: Huygens image simulation did not automatically detect when the resolution in image space was set too low.
FIX: Rendering of Gaussian beams in the 3D view was broken when the beams propagated parallel to the surface coordinate system.
FIX: Paraxial lenses did not trace rays when the focal length was set to infinity.
FIX: Several minor fixes and improvements.
