🖥️ Graphical User Interface (Preview Release)
-
First Public GUI Release
An interactive desktop interface built with PySide6, providing access to key modeling and analysis tools without requiring code. -
Surface Sag Viewer
Visualize surface sag profiles directly in the GUI for fast and intuitive inspection. -
Live Analysis Plots
Dynamic plotting tools integrated into the GUI for rapid design diagnostics.
🧪 Modeling & Analysis Enhancements
-
Temperature & Pressure Dependent Index
Refractive indices can now be computed as functions of temperature and pressure, supporting more realistic and adaptive modeling. -
Angle vs. Height Plot Type
New analysis plot for tracing ray angles against height, useful for telecentric or afocal systems.
🧠 Optimization System Upgrades
-
Total Track Operand
A new operand for objective functions based on total optical track length, useful for constraining system size or managing physical layout. -
Glass Expert (🚀 New Optimization Type)
A major addition to the optimizer: automatically explores and selects optimal glass types for a given design, intelligently navigating the glass catalog during optimization. Brings Optiland closer to expert-level design support.
🧰 General Improvements
