We have 200nm thick Aluminium foils and we need to find out the amount (percent) of UV light (100nm-300nm) they transmit. The CXRO website provides very reliable data but in the EUV/XUV range. Link : https://henke.lbl.gov/optical_constants/filter2.html

We require the same information but in the UV range. An order of magnitude estimate for percent transmittance will be useful as well.

Thanks.
