Introduction:
Silver coated mirrors(Silver coated on quartz glass, BK7 glass substrates) offer the highest reflectance in the visible to IR spectral range over all the metal coated mirrors. In order to protect from oxidation these silver mirrors have an overcoat of SiO. With the exception of the UV, silver is an ideal choice for high reflectivity from 500nm to 2.0um.

Substrate Material:
BK7 optical glass
Outer Diameter:
38.1, -0.2/+0.0mm
Thickness:
6.3, +/-0.1mm
Surface Quality:
Double side fine polished; 40-20 scratch and dig
Flatness:
<Lambda/10 @ 633nm over clear aperture(>85% of outer diameter 25.4mm)
Chamfer:
0.3mm x 45-deg protective
Coating:
Single side silver coating, with protection layer
Reflectivity:
Ravg>96% from 400nm-700nm, Ravg>96% from 700nm-2.0um
Parallelism:
<3 arc minutes
Clear Aperture:
>90% of reflective surface
Back Surface:
Polished and uncoated
Damage Threshold:
>0.5J/cm2 (10ns pulse, 1064nm)
Packaging:
Vacuum packaged(sealed)
