Paper Abstract

Using its patented VQ™ finishing process, Raytheon EO Innovations has been producing low-scatter, low-figure and affordable aluminum 6061-based mirrors for long stand-off intelligence, surveillance and reconnaissance (ISR) systems in production since 2005. These common aperture multispectral systems require λ/30 root mean square (RMS) surface figure and sub-20Å RMS finishes for optimal visible imaging performance. This paper discusses the process results, scatter performance, and fabrication capabilities of Multispectral Reflective Lightweight Optics Technology (MeRLOT™), a new lightweight substrate material. This new technology enables lightweight, common-aperture, broadband performance that can be put in the hands of the warfighter for precision targeting and surveillance operations.
