Hi,
The UV Index is a linear scale, so you should use a multipler to correct for any attenuation that you introduce, or to correct for calibration errors (except for any zero/bias offsets).
One problem is identifying a material which is (semi-) transparent to UV. I suggest a sheet about half a mm thick of PTFE (Teflon). See post #98 here.
Cheers, Alan.
