OCA Applied Optics is fabricating an innovative 0.9-meter diameter, ultra-lightweight, all- beryllium space telescope for the NASA Goddard Space Flight Center Multi-Beam Laser Altimeter. The telescope is also a prototype for the GSFC Geoscience Laser Altimeter System for measuring ice sheet topography, temporal changes in topography, cloud heights, planetary boundary heights, aerosol vertical structure, and other topographical features. The telescope is being manufactured using efficient and innovative approaches to optical grinding and polishing and electroless nickel plating of the large parabolic primary mirror. Advancement in producibility were accomplished utilizing novel tooling concepts and advances in manufacturing equipment. Improvements include rapid material removal in grinding and polishing and uniformity of electroless nickel plating.
