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/Dimension:
50.8x50.8,+/-0.2mm
Thickness:
6.0,+/-0.2mm
Surface Quality:
Single-side polished(SSP); 40-20 scratch and dig
Flatness:
<Lambda/4 @ 633nm per 25mm
Chamfer:
<4-corner with radius 1mm,ground surface
Coating:
Single side silver coating, with protection layer SiO
Reflectivity:
Ravg > 97% for 450nm - 2,000nm & Ravg > 95% for 2,000-20,000nm
(Ravg>96% from 400nm-700nm, Ravg>96% from 700nm-2.0um)
Note: protective SiO overcoat protects from oxidation
Silver coating highly reflects in visible and NIR range
Parallelism:
<3 arc minutes
Clear Aperture:
>90% of reflective surface
Back Surface:
Back surface: ground (120-grit)
Damage Threshold:
>0.5J/cm2 (10ns pulse, 1064nm)
