These optical coatings are being commercially sold under the trade name "DURACON". They have emissivity as high as 98 to 99+% over a broadband ranging from almost 500nm in the visible to 20 micron mid-infrared region. Moreover, the coatings can be deposited on metallic, ceramic polymeric and glassy surfaces with equal facility and adherence. Applications include medical diagnostic instrumentation, automated vision systems, spectroscopy and spectrometry and space optics. Coatings have been featured in "Photonics Spectra" and other trade and scientific publications.
