 # Example 10: NSC ZRD Filter String 

 Last update: 17.07.2025 

Ex 10: A sample file is opened, all detectors are cleared, and a ray trace is run while saving a ZRD file. The ZRD file is played back on a detector viewer window, while a filter string is applied to the detector. The number of ray hits and total flux is retrieved from the detector for each pixel. For Premium only, a Ray Path Analysis window is opened, the ZRD is loaded and the output is saved to a text file.

```
Input:      Non-Sequential\Ray Splitting\Beam splitter.zos
<p>Output:     API\e10_NSC_ZRD_filter_string.zos
API\e10_API_Raytrace.ZRD
API\e10_RayPathAnalysis.txt (Premium Only)
</p>
```
