   Custom interference filter

   We’ve been buying custom interference filters to do Rb optical pumping   
   from Intor.  We haven’t purchased these for a few years and the price   
   from intor has now jumped by over 50% ($135 to $220).  I’m looking for   
   other sources.   
   I’ve got a quote coming from Custom Scientific, and online quotes   
   submitted to optometrics and Omega filters.  Any other ‘good’ sources   
   I should talk to?   
      
   It’s a bit hard to define the specs for this filter in the standard   
   way.  (center wavelength and FWHM.  Because all I really care about is   
   blocking the 780 nm line of Rb and passing the 795 nm line.  I want   
   the edge of the filter to be right between the two, and other details   
   are not as important.
