For => very good catalog UV mirrors try:

Acton Research   508-263-3584

Janos Technology   802-365-7714

Newport Corp.   800-222-6440

Are you using broadband UV coatings or those specified for 266 nm at 45 deg
Angle Of Incidence (AOI)?

I have used both CVI and Newport 266 nm 45 deg AOI mirrors in my laser
spectroscopy system and measured results consistent with their catalogs.  In
CVI's catalog R~99% for S and R~9% for P polarization.
