Welch Mechanical Design, LLC — National Aeronautics and Space Administration SBIR Phase I: S1

Description

<p style="margin-left:0in; margin-right:0in">Welch Mechanical Designs (WMD) proposes to develop a highly efficient and innovative process for polishing the substrate of high performance optical quality metal mirrors directly, eliminating the need for nickel coating and reducing the number of steps involved, thereby significantly reducing cost, risk, and manufacturing time of telescopes and other optical structures that are suitable for a wide range of imaging applications.&nbsp;</p><p style="margin-left:0in; margin-right:0in">This direct polishing process will have a significant impact on the cost, time, and risk, associated with the fabrication of optical assemblies such as compact and lightweight Cassegrain telescopes compatible with existing differential absorption lidar (DIAL) and HSRL lidar systems.&nbsp; The process also allows aluminum to be used to rapidly make larger aperture, stable, monolithic telescopes and optical structures that are suitable for a wide range of imaging applications in aircraft and space deployments.</p>
