Changelog v26.06
|
NEW: Solves for parameters within the optical design editor.
Possibility to solve for focus / pupil position (marginal ray solve, paraxial ray solves) alignment of surfaces or lenses (chief ray solves) as well as curvature solves.
|
|
NEW: Larger improvement to the Wave Optics Toolbox. More accurate wave optical propagation for high NA systems.
|
|
NEW: Additional options for apodization (Lambertian / Isotropic).
|
|
NEW: RGB Irradiance plot.
|
|
NEW: Full polarization support for Gaussian beam sources.
|
|
NEW: Polychromatic MTF optimization goal.
|
|
NEW: Thermal expansion coefficient optimization goal.
|
|
CHG: More than one Zernike tolerance allowed per surface.
|
|
FIX: Compensators were applied to nominal merit function.
|
|
FIX: Ray highlighting did not work in the patch version v26.02.4.
|
|
FIX: Many smaller fixes and improvements.
|
|
Changelog v26.06.01
|
|
FIX: PSF / MTF sometimes reported zero intensity for sequences with aperture type none.
|
|
FIX: PSF / MTF did not work for fields at exactly 90° angle (wide angle).
|
|
FIX: Compensators in tolerancer in some cases used wrong merit function within the latest release.
|
|
FIX: Analytic intersection of Axicon with tip-radius did not work properly in some cases.
|
|
FIX: Export of Sensitivity Tolerance data to CSV did not work.
|
|
