#222nmUVC

🚨very interesting 🧵 by @nukit.bsky.social (on Twitter) discussing the importance of measuring the output of Far-UVC not just at the nadir, but also total radiant power output... Clear, concise, and informative threadreaderapp.com/thread/19413... #CleanAir #IAQ #FarUVC #222nmUVC

A device called a goniophotometer is used to measure the light from every angle, and that gives us a picture of the three-dimensional power output- which can be shown on a polar plot.

Below that are two diagrams. One is of the testing setup. The other is a polar plot of the energy output of the device.
