   Hi:   
      
   1-What causes polarization coating (the hypogenous interface) of a Polarizing   
   Beam Splitter Cube go bad and sometimes delaminated?  I could think of   
   humidity+temperature.   
      
      
   2-Do you of any company and supplier who have Polarizing Beam Splitter Cubes   
   without this problem?   
   We'd like BPS Cube to have a "3 deg fielField of View" and " Extinction Ratio   
   >500".  Operating Wavlength is ~900nm   
      
   Your supplier suggestions and comments are greatly appreciated.
