Using the Chart as a Guide When Ordering Precision Mirrors and Mounts:
40 = 40 inch parabolic or vertex focal length
015 = 1.5 inch off-axis distance - specified along perpendicular from optical axis to inner edge of mirror
08 = 8 inch diameter
Standard Manufacturing Tolerances
Focal length: +/- 0.5%
Diameter: +.000" -.005"
Off-Axis Distance: +/-0.02" (standard configuration), +/- 0.125" (stand-alone configuration)
Edge Thickness: +/-0.05" (12" focal length or less), +/-0.10" (18" focal length or greater)
Surface Quality: 60/40
Surface Accuracy: Specified over 90% of the clear aperture area (Test Wavelength 0.6328 microns)
1. Standard Coating: AlSiO.
2. Focus Position of the OAP is oriented in the mount at 9 o'clock unless otherwise specified.
3. Stand-alone configuration OAPs are manufactured directly as off-axis segments.
4. High Quality (Q) Mirrors are l/8 from 12" focal length and longer. l/5 from 3" to 6" focal length.
5. Superior Quality (SQ) Mirrors are up to l/20 (please specify when requesting a quote).
