Laser Gold Technical Data
Reflectivity:
Laser Gold plating reflectivity is
greater than 97% at 0.7 microns and greater than 99% at 10.6
microns when measured on a low-scatter substrate. The reflectivity
in the infrared equals and often exceeds that of a freshly
vapor-deposited gold. Because of its outstanding cleanability,
stability and reflectivity, the National Bureau of Standards,
(NIST), chose Laser Gold plating as the Standard IR reference
material (#2011). For more than fifteen years Epner Technology
has been the sole source supplier of these standards.

Emissivity:
Measurements made by a variety of aerospace
companies confirm Laser Gold’s theoretically low emissivity.
While a value of .02 is consistently obtained on polished
substrates, ETI has been able to modify, electrochemically,
sufaces that are too delicate or too convoluted to permit
physical polishing. The surface of machined materials, Be
or Al, for example, can achieve a consistent emissivity of
.03 to .05.
Indeed, the ability to achieve a repeatable emissivity value,
whatever the substrate, has made Laser Gold the coating specified
on an impressive array of military and space programs.

Note:
A number of Government and Aerospace contractor Laboratories,
both here and in the UK, are part of a continuous characterization
of the optical properties of Laser Gold and Laser Black.
As this data becomes available, it will be posted in this
space, however due to possible competitive situations,
the organizations that produced the data may not always
be identified here. |
