The MAIN SPECIFICTIONS for the mirrors are:
Surface profile: Flat
Residual Tangential Radius of curvature: > 200 Km and Concave
Residual tangential slope errors: < 0.5 microrad rms
Residual tangential shape errors on the central 300 mm: < 0.5 nm rms
Residual tangential shape errors on the central 900 mm: < 1 nm rms
The microroughness of the optical surface shall be below 0.3 nm rms measured in the 20 nm - 1 mm spatial wavelengths.
The Vendor shall be able to provide optical metrology prove of the achievement of the required specification prior the delivery of the optics.
