Subject: 1550nm super steering mirrors have arrived 

The set of 60 mirrors we ordered from Coastline have arrived. Measured HR reflectivity is about 99.994% at 45 degrees AOI for unspecified polarization, and AR reflectivity looks to be about 0.04%. These mirrors have a 1 degree wedge, are marked on the barrel with serial numbers and an arrow pointing to the HR side. From the optics I unwrapped so far it seems that the arrow is located on the thicker part of the barrel, although no such thing was specified on the quote.
