We’re excited to introduce a new feature experiment: NSC Sequence Selector in Ansys Zemax OpticStudio 2025 R1.01! This tool is designed to help you track, filter, and analyze rays following a specific optical path in Non-Sequential mode by generating persistent sequence filters.
This tool allows you to:
- Identify and track unique ray sequences
- Assign and modify sequence filters
- Use sequence filters in analyses and save/retrieve them
- Maintain persistent sequences throughout the system
This feature can be useful for component-level stray light analysis in applications like cellphone cameras, VR/MR devices, HUDs, and folded optical systems.

You can access the Sequence Selector from the Help Tab in Non-Sequential mode:
Help > Test Lab > Feature Experiments > Sequence Selector

Your input is crucial in shaping this feature for future releases. Try it out and share your experience in this thread. Let us know what works, what doesn’t, and any improvements you’d suggest.
