Almost everyone who attends the SPIE DSS Exposition has received a gold-plated paper clip from Mr. David Epner, personally. Well, the gold costing that Epner supplies to the optics industry has some interesting infrared reflectance (and emittance) properties.

Those properties, specifically the hemispherical spectral reflectivity in the near, mid and far infrared is now available for all to view first hand on the Epner website. A copy of the curve and the data related to it can be downloaded from the site, too.
