16 inch diameter flat mirror

The National Aeronautics and Space Administration (NASA) is seeking a quotation for a 16 inch diameter flat mirror to be used for an optical alignment station. The mirror should have a substrate material of low-CTE glass, a diameter of 406.4 mm, and a thickness of 50.80 mm. The surface should have a clear aperture of at least 375 mm, a flatness of lambda/10, and a quality of 60/40 per MIL-PRF-13830B. The mirror should also have a protected coating with an average reflectance of greater than 90% from 400-700 nm. • The mirror should be delivered to NASA's Marshall Space Flight Center in Huntsville, AL. • The vendor should provide inspection reports certifying the performance of the mirror. • The vendor should be registered in the System for Award Management (SAM) database. • The quotation should include the vendor's SAM UEI/CAGE code.
