- The 3D view now uses a consistent dark background, even in Light Mode. - Increased ray brightness for clearer contrast against the background.

1. Compute a best common focal plane from cell second moments, then apply it to the standalone prescription with undo. 2. Compare 11 through-focus planes using combined and worst-cell RMS, with candidate application. 3. Combine three wavelengths geometrically and incoherently with adjustable input weights. 4. Inspect centroid-referenced geometric R80/R95 radii and per-cell transmission. 5. Evaluate prescription sensitivity to radius, conic, A₄, or substrate-thickness perturbations. 6. Compare the selected cell’s field-dependent centroid with a paraxial linear reference. 7. Inspect an entrance-pupil map of successful and unsuccessful ray samples with failure reasons. 8. Compare nd/Vd material variations using equal-weight F/d/C lines. 9. Map cell surface sag and remaining substrate thickness with CSV export. 10. Optimize a weighted polychromatic common focal plane, with application and undo support. Also includes freeform microlens prescriptions, array assembly, surface normals, capture/crosstalk, mean/worst-cell scan objectives, alignment tolerances, and baseline comparisons. Improved scientific input, small-coefficient display, and editing across cell selections. Retains the iPad workspace with adaptive layouts, collapsible details, and bilingual guidance.

This update expands optical design capabilities, improves project management, and refines the Mac and iPad experience. • Project Management: Switch between multiple projects, create blank designs, and reopen or restore recently closed and deleted projects. Improved autosave, version snapshots, and external-file conflict handling. • Interface & Interaction: Redesigned the welcome screen and refined sidebars, inspectors, and optical viewports. Moved wavelength and ray-color controls into the inspector and improved parameter entry and surface selection. • 3D Modeling: Improved the appearance of lenses, mirrors, aperture stops, and 3D ray bundles. Separated the component library from examples and expanded support for aspheres, freeforms, and coordinate breaks. • Sources & Spectrum: Added collimated, finite-distance point, converging, Gaussian, and extended-source options. Configure wavelengths from ultraviolet to infrared, spectral weights, and reference wavelengths, with separate material-validity checks. • Power & Coatings: Added optical power budgets with separate reporting of geometric throughput, output power, absorption losses, and detector signal. Added reflection, transmission, and absorption analysis for complex-index thin films. • Imaging & Analysis: Expanded finite-conjugate, Gaussian-pupil, and broadband PSF/MTF analysis. Added grating-efficiency, fiber-mode, and bend-propagation analysis. • Optimization & Exchange: Added weighted merit functions, multistart optimization, and sensitivity analysis. Expanded Zemax text import with clearer compatibility reporting. • Reliability Fixes:Fixed crashes when focusing empty designs, unexpected keyboard dismissal during editing, and missing actions in Recently Deleted. Added independent numerical benchmarks, sampling-refinement comparisons, and improved clearing of invalid results. Analysis features have defined model assumptions and operating limits. Consult the in-app guidance and convergence checks when interpreting results.

• Start with a blank project and switch between multiple open projects using tabs. • Rename, duplicate, close, and reopen projects. Restore deleted working copies. • Access materials, analysis, and optimization tools within the optical design workspace. • Select a target optical surface and apply materials directly from the library. • Enjoy a new blue-violet mesh launch animation and refreshed workspace styling. • Added Chinese and English text for the new features.
