Gold
MIL-G-45204
AMS-2422 & 2425
ASTM-B-488
A gold coating can range from matte to bright finish. It demonstrates good corrosion resistance, has high tarnish resistance and provides a low, electrical contact resistance. It also acts as a good conductor. Gold has a high reflectance capability for infrared light and in the form of Laser Gold, which exhibits the highest IR reflectivity done by any electroplating process.

Conventional physical models of light scattering often neglect the fundamental wave nature of light, inevitably leading to inaccuracy. From its early applications to radiation sources, coherence theory is currently being extended to the description of light scattering, providing more accurate predictions and discoveries of effects beyond the assumptions of conventional models. Advanced Optical Technologies (AOT) has developed several coherence models of light scattering that have been verified against radiometric and materials data, including AFM data for rough surfaces. Applications including bio-medical imaging and diagnosis, computer-graphic design, and radiometric M&S and data analysis benefit from physical models of light scattering that account for wave effects. Epner Technology supplied AOT with samples of our diffuse gold coatings for this study.
