What this tutorial covers
Perform exact sequential ray tracing and inspect the system and surface data.



Step-by-step workflow
1Open the module
Open Exact Sequential Ray Trace. Confirm that the visible page really matches the tutorial topic before changing any settings.
2Configure the input
Prepare and check the optical-system layout, surface parameters and tracing conditions.
3Run and watch the status
Confirm the optical system, run the trace and inspect the resulting system tables. Watch the visible status, plot or log area while the workflow is running.
4Inspect the result
Pay special attention to the sequential-trace result and the system/surface summary.
5Verify and iterate
Sequential ray tracing depends strongly on a consistent system definition, so re-check the model after changing surface parameters. Change one meaningful parameter and rerun so you can verify whether the output changes in the expected direction.
How to read the result
- The main output of this workflow is the sequential-trace result and the system/surface summary.
- Read the result together with the exact inputs used for the run; a screenshot alone rarely tells the whole story.
- Sequential ray tracing depends strongly on a consistent system definition, so re-check the model after changing surface parameters.
Troubleshooting & practical tips
- If nothing changes, first confirm that the correct module is open.
- If the output looks unrealistic, check units, field mapping and input scale first.
- For comparisons, change one key parameter at a time whenever possible.
