How to change the screen size or resolution when viewing a small focus image?

[TWANG006]

I am new to xrt. I just tried a very simple example with a point source, a toroidal mirror and a screen. The screen was positioned at the focus, as seen by the image below.

However, it should see the aberration when zoomed in, as shown in the image below.

This can be done by xrtGlow by zooming in the plot with mouse. But I was not able to achieve the same result using the xrtQook GUI with the plots function.

How can I visualize the aberration with a finer screen grid or smaller screen? Thank you so much in advance.

Hi!

xrtGlow provides a preview, it was not meant to operate millions of rays and make fine histograms. However, you can achieve this in a script where you can accumulate zillions of rays in a selected view region. xrtQook can make such a script for you but you can also write it yourself following the supplied examples and the documentation. xrtQook also makes viewing the documentation easier because it is rendered in the Qook's right panel.

Create a plot that visualizes the local beam of your screen01. Optionally modify its x and z axes in limits and number of bins. Optionally change the color axis to a beam property that you want to emphasize by color. Save the script and run it. You can make all modifications right in the script before you run it, you don't have to re-introduce them in Qook and then re-create the script.

For educational purpose, please put the resulting plot in this thread.

Thank you so much for the advice. I will give it a try and post the result here as a future reference.
