Hi,
It appears that those domes are made from Acrylic plastic (which is also known by the trade name "Plexiglass").
I happened to find this link which might be helpful.
It looks as if only the type "G UVT" would transmit (pass) the ~300 nm wavelengths which are the "correct" frequency to measure the "Official" UV Index. But some "UV Index" sensors measure only UVA (around 350 nm) and "assume" that the UVB will correlate.
Cheers, Alan.
