   Steve.  You are looking for something that isn't very available.  I've   
   searched ongoing for years. The only solid state camera sensitive in the   
   1.2-1.6 range and the last price I had on those is over $15k USD.  This is   
   considered the SWIR range.  Btw,    
   the use of a filter on a ccd is useless.  I have a vidicon camera with the   
   extended IR range sensitive out to 2.2um.  The other guy didn't say so but the   
   last tube of this type I bought cost me $3000 and that was over 5 years ago.    
   The silicon CCD has no    
   sensitivity out that far in the IR. They are only good to about 1.1um at best   
   and that is where the sensitivity goes well below 1%.  I have one of these   
   SWIR cameras and I also have one of the IR 2.2um vidicon  cameras.  I can rent   
   these but it will be a    
   little costly.  EMAIL me at business4512@gmail.com.  Bill
