[Dsg-rich] five RICH planar mirrors inspected

[Tyler Lemon]

Hello, 

This afternoon we inspected five RICH planar mirrors. Attached are photos of each mirror during inspection. 

All mirrors did not appear to have any large scratches or issues. 

Mirror A1L-R02 had a small (~1 mm) chip on one corner and a small scratch (~ 3cm long) on one side. Photos of the chip and scratch on Mirror A1L-R02 are included. 

We partially removed the blue protective film on only two mirrors, A1L-R02 and A2L-R02. All other mirrors' reflective surfaces were previously inspected in Italy by Marco Mirazita so we did not have to remove any of the blue protective film. 

When we partially removed the protective film, we could see that there are streaks left behind from the film. We did not try to clean these but think they could be cleaned if we had the proper cleaning device and cleaning solution to use. 

All mirrors were repacked in their original packaging and are stored leaning vertically on a wall in EEL 124, DSG small cleanroom. 

Best regards, 
Tyler
