Chapter 6  Maintenance 

There  are  no  serviceable  parts  in  the  PDA10JT  detector  or  power  supply.  The 
housing  may  be  cleaned  by  wiping  with  a  soft  damp  cloth.  The  window  of  the 
detector should only be cleaned using isopropyl alcohol and optical grade wipes. 
If you suspect a problem with your PDA10JT, please contact your local Thorlabs 
technical support office and a member of our support team will be happy to assist 
you.
