AR Optical Window Replacement
« on: October 07, 2020, 11:59:35 PM »
I need to replace the scratched AR window on my QHY168C.  I have the part.  How do I dissemble? What will remove the existing glue?  Will alcohol dissolve it?  What type of cement/glue should be used on the new window?  Thanks.

Usually we break the glass and replace it with a new one. We use 704 silica gel.

Thank you for your reply!  It appears that I need to remove the anti-dew assembly.  After taking out the four screws, how do I remove it?  It feels like it may be attached with a soldered connection?  I appreciate your help.

Hi,

Yes,You need to open the solder joint with a soldering iron.
