   I use 365nm all the time for holography, and have also needed large diameter   
   optics.  Largest I've found with AR coatings for that wavelength are 100mm,   
   and they were made of BK7, which is about 90% transmission there (uncoated).    
   Not true for N-BK7.  I'   
   d be looking for BK7 lenses and someone to put a custom AR coating on them.    
   Or use mirrors.
