About this file
This document contains technical specifications for magnesium fluoride windows and relates to a federal contract opportunity with the National Aeronautics and Space Administration Shared Services Center. The specifications provide detailed technical requirements for rectangular magnesium fluoride windows, including that optical surfaces are to be polished to 2 fringes of power and 2 fringe of irregularity, meet a 60-40 scratch dig specification, and have a clear aperture within 0.020 inches of the perimeter on optical faces. Dimensions, tolerances and notes on material, surfaces, and angles are also provided. The related solicitation seeks these magnesium fluoride windows and was issued under solicitation number 80NSSC24852889Q.
