Download Guide

Infragold NIR-MIR Reflectance Coating is an electrochemically plated, diffuse, gold-metallic coating which exhibits excellent reflectance properties over the wavelength range from 0.7 to 20 μm. Infragold has excellent vacuum stability, with no outgassing reported. Laser damage threshold is approximately 19.3 J/cm2 @ 10.6 μm using CO2 laser.

This is considered above average for a plated surface. The threshold will increase if the material is cooled on exposure to laser, as in water-cooled integrating spheres or targets.

The typical reflectance of Infragold is >94% above 1000 nm and data is traceable to the National Institute of Standards and Technology (NIST). Infragold can be applied to metal parts, generally aluminum, nickel or steel, although it has been applied with success to copper and tungsten. It is generally used for reflectance integrating spheres and accessories for NIR-MIR applications and is suitable for many space applications.
