Table 1.

Surface tolerances using the High Precision tolerances from Edmund Optics. Note that we use precision for the Radius, as high precision would mean 0%, which would be unfeasible.

	Surface Tolerances
Radius	0.1% (precision)
Thickness	0.01 mm
Decenter X	0.01 mm
Decenter Y	0.01 mm
Tilt X	0.0167°
Tilt Y	0.0167°
Irregularity	0.2 fringes
