Share Your Feedback: NSC Sequence Selector Feature Experiment in Ansys Zemax OpticStudio 2025 R1.01
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 theHelp 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.

NSC Sequence Selector seems very appealing.
Where can I download 2025 R1.01?
So far, I can only find R1.00.
Solved. I found it through the AnsysInstaller.
Yes, as previously announced, starting with the 2025 R1.01 release Ansys Zemax OpticStudio is no longer available as a standalone installer on download.ansys.com. Instead, it is now part of the Ansys Automated Installer, which simplifies installation and updates across Ansys products.
This new installation process may make the process easier for ANSYS, but definitely not for the customers.
Seems like a very nice new feature. Hangs a lot. Could be my fault… without any documentation it’s not entirely clear what it does, or how to use it.
But the installer is an abomination…
2025 R1.00 installed as 1.53 GB and 451 files not using the Ansys installer
2025 R1.01 installed as 4.13 GB and 115,974 files using the Ansys installer, including for example 86,861 Python files for Fluent CFG which I don’t use and don’t have a license for. And it gave a ***WARNING*** about a missing NVIDIA driver for Speos on a system which doesn’t have NVIDIA graphics and doesn’t have Speos. And as always it overwrote my COATINGS.dat file, so no progress there.
@Tom Pickering Do I need to download a new automated installer every time there is a new version of OpticStudio?
Hi Sean,
Here is an alternate way, but it’s “less than optimal”. If you already have 2025 R1, jump to step 2.
1- From the section “Primary Packages (Commercial & Academic Packages)”, subsection “Optical”, you download the normal release (“Zemax OpticStudio”, 1.1 GB file “OPTICSTUDIO_2025R1_WINX64.zip”). This is 2025 R1 (files date from December 2024).
2- From the section “Service Packs” at the bottom of the page, subsection “Legacy Service Pack Installer”, you download the 7GB “Service Pack 1” (file “ANSYS_2025R1.01_WINX64.zip”).
3- Extract the 40 MB Zemax archive from it (“25101_zemaxos\WINX64.7z”). It does not contain a full Zemax installation, nor an installer or msi file, only a subset of files. I guess you or your IT need to copy these files in your Zemax folder.
By the way, I just wanted to find the release notes for R1.01, since they are not published anywhere, but they are not in the archive. So no idea what’s the difference between R1 and R1.01 in terms of bug fixed.
@sjhart For more information, please check out the Help Files.
@Ray You can find the release notes for Ansys Zemax OpticStudio 2025 R1.01 in the Ansys Help oLink]
and how were we supposed to find these Ansys Release Notes on our own without you telling us and sharing the link here? Where is this link officially publicized to the community? I just happened to see it here, but now I will know to look in the future.
