[Dsg-rich] RICH planar mirror B2 inspected, stored in EEL 121 small clean room

[Tyler Lemon]

Hello Marco, 

Yes, it is correct that the mirror did not have the blue protective film on the surface. 

There was only a layer of blue cloths wrapping the mirror. 

Regards, 
Tyler

Hi Tyler, 
thank you. 
I confirm, there is a few mm gap between the two half of the glass 
sheets. 
>From the pictures it seems that this mirror didn't have the blue 
protection on the surface. Is it rught?
