Comments: | - Opened up optics to discover the reflection optics are very soiled (see attached image)
- Need to fully disassemble optics to clean out properly in an IPA bath.
- The transmission optics have been discovered to be quite dirty as well.(see attached image)
- Removal of the stage has discovered that silicon has been applied in a poor manner to keep a seal on, but this has overflowed to stick the stage on in the back left corner. Cleaned up and removed this excess silicon.
- Removed the "O-ring" seal, and brass shim surrounding the transmission optics.
- Can& 39;t remove the transmission optics itself, so we& 39;re cleaning it in place with canned IPA and Q-tips making sure to clean the diode surfaces too.
- Cleaning the reflection optics in a bath of IPC and agitating
- Disassembling all the transmission optics and fully cleaning in ultrasonic bath, lots of rust everywhere.
- After cleaning, discovered some of the matte black paint on the stage has been removed - this puts into question the quality of the data going forward. Need to check data going forward.
- After full cleaning in bath, and rust removal with glass fibre pen and lots of q-tips, everything looked good. But after a while in the oven, Ian discovered liquid still in the reflection optics head. We took it apart a bit more to remove the excess water and while apart, put it in the oven for a few more hours.
