Agreeing with Marc....  There was a string on this subject about two years
ago which should be found in the Museum-L Archives, but the bottom line
advice that we decided to follow was to use roll down UV shades so as to
minimize sinking mounting fixtures into the historic woodwork and to not
risk damaging the historic glass panes.

It's not just the material you use, but the technique.  For example, you 
probably would not want to use a direct-applied film on historic glass. 
Your options also will depend upon whether the window has curtains or other 
surrounds to mask mounts, whether you are wanting to screen UV only, or UV 
plus some of the daylight, exactly what your definition is of "relatively 
invisible," and how much (or little) money you want to spend.  I have worked

with a number of client museums to refine a light control plan that is 
specific to their needs.  I'd be happy to give you some suggestions if you 
can provide a bit more information.
