Low Emissivity Coating LE-1


This coating is a low thermal emission system. The coating is made of thin gold applied to a relatively non-magnetic base layer of chrome, stabilized chrome/nickel alloy, or a proprietary oxide. The coating has low thermal conductivity, making it an effective choice for cryogenic cabling and heat pipes. The LE-1 coating is usually used to control thermal losses in devices operating at 4 to 10 degrees Kelvin.


Each layer is less than 0.1 microns thick. Typical computed hemispherical emissivity is less than 3% for cold sources (Far IR). LE-1 systems can be applied to metals, glass, ceramics, plastics and epoxy resins.
