The (probably) last instrument type in the series is the slit-collimated system (in the past, I did one on a SAXS system, and the homebuilt Ultra-SAXS instrument). Now that I am in a lab where we have one of these instruments available, we managed to record a short introductory video. I hope you’ll enjoy it!
Thanks to Anton Paar for spotting a small flaw in the initial video. Other than that, this video is not affiliated in any way with them.
