method of cleaning may be carried out for the  diamond material than 
could be achieved with the ZnSe or Ge puck options. More aggressive 
solvents and abrasive cleaners could be considered for use to remove 
the sample, if necessary. 

 

Warning: 

Aggressive  cleaning  procedures  suitable  for 

diamond  will  very  likely  cause  irreparable  damage  to 
ZnSe or Ge materials. Make sure the cleaning procedure 
is suitable for the crystal material employed.
