Released: January 19th, 2020
OpticsViewer 21.1 contains the following fixes and enhancements.
Bug Fixes
- GRIN – Fixed an issue with GRIN materials in the Single Ray Trace and Polarization Ray Trace where the individual ray was using the local vertex refractive index and not the refractive index at the ray intercept. This only affected the reported direction cosine at the given surface and did not affect the actual GRIN trace to the image plane.
- Spot Diagram – Spot Diagram now correctly displays the units in afocal mode. Calculations are not affected.
- Optimization Operands – Optimization operand ACOS (arc cosine) input now rounds input values greater than +1.0 and less than -1.0 to exactly +1.0 or -1.0 respectively before taking the arc cosine of the input value.
- Zemax Black Box – Improved handling of vignetted rays inside a ZBB Black Box file.
- Layout Plots – Fixed a bug in sag rendering for Q-Type Freeforms in layout plots. This bug did not affect the ray trace algorithm.
- Interferogram – Fixed behavior in the Interferogram analysis settings which caused all values to reset to their defaults when pressing F3 or clicking the Undo button.
