EXAMPLE 53
20.0 		= Off-axis distance
= OAA degrees 		 


Diameter tolerance: +0/-1mm
Thickness tolerance: +0/-2mm
Focal length: +-1%
Off-axis distance: +6mm -0mm (mirrors above 100mm diameter)
+/- 1mm (mirrors =<100mm diameter).
Surface accuracy: lambda /10 p-v@633nm across entire clear aperture. Slope errors Interferograms and analysis showing surface accuracy are supplied with all mirrors using industry standard software.
Micro-roughness: 1.2nm rms. Measurements of roughness are not included in price.
Surface quality: 60/40 to MIL-O-13830 Rev H in which 60=60microns and 40=0.40mm.
Materials: Zerodur is atandard for mirrors of 125mm diameter or less.
Mirrors above 125mm are made from fine-annealed low expansion glass unless otherwise requested.
Coating: Al+MgF is included in our standard list price. Spectral scans free if requested at the time of order.
Silver, gold high-power laser, and Femto-second laser coatings quoted for on request.
