This is mostly just a vent, though I'd be interested in a different vendor.   
      
   So we get mirrors from CVI laser for a FP cavity.  We've ordered these as pairs   
   in the past (both from the same run.)   
   The last order we neglected to stipulate the pairs   
   and we received four mirrors with no match.   
      
   Well I thought maybe the matching is not that important   
   and I tested two unmatched mirrors.   
   No go, I could easily see the non-symmetry in the spectra.   
      
   So I contacted CVI, said about my mistake, and could we have these   
   as pairs in the future.  (And for the rest of this order.)   
   And can I return these four mirrors.. what's the restocking fee?   
      
   The answer I got today is that it's a 50% restocking fee, because these   
   are custom mirrors and they can't resell them.  Huh, how can they be custom   
   mirrors   
   and yet I'm getting singles.... Hmm maybe I'm just getting odd numbers.   
      
   That for letting me vent.   
   Any other good source for high reflectivity curved mirrors?
