Subject: Choice of folding mirrors in the RC cavities 

In addition to the main mirrors (PRM, SRM) we will also have fold mirrors (called PR1, PR2, SR1, SR2). I am curious to see if we can get away with just using commercial optics; I think that the CVI Y1S coatings may do the trick.

The above plots show the reflectivities v. wavelength. I've asked the sales rep to give us specs on the reflectivity v. angle. I bet that we can guess what the answer will be from these plots.
