Near- and Mid-IR Gold Coatings and Materials

Avian Technologies introduces two new gold materials that combine the high reflectance of Epner LaserGoldĀ® and the surface preparation technology of Avian Technologies to give optimum diffuse reflectance in the near- and mid-NIR. The NIR coating utilizes practically any metallic substrate and is most effective in the 1.0-6.0 micron range. The mid-IR material is a new technology in IR diffuse reflectance that combines Epner’s plating expertise and sintered metal technology from Avian Technologies. This coating is best suited to applications in the 2 micron to 25 micron (or greater) wavelength range.

Reflectance of the NIR Coating is >94% throughout its specified range. The mid-IR Coating exhibits total hemispherical reflectance of >90% from 2 microns to >25 microns.
