Laser Gold Spectral Reflectance Graphical Data

Laser Gold Spectral Reflectance Graphical Data

This reflectance chart depicts measurements made by three separate organizations, China Lake Naval Weapons Center, (measurement made under the renowned Jean Bennett), Hughes Aircraft’s Optics Lab, then in Culver City, Ca. and AZ Technology, a NASA source in Huntsville.  In all cases, the measurements were made with the Laser Gold plated over a highly polished, low scatter electroless nickel substrate.  At 700nm wavelength reflectivity is an astounding 97% and >99% @10 microns.  Measured at 6 degrees angle of incidence.
