GOLD - FSG98 And More!

Gold coatings make excellent mirrors for long wavelength applications as they have very high reflectance from 700nm through the far infrared. They are also chemically inert, so that with a thin protective layer for abrasion resistance, they make very stable, durable mirror coatings. FSG98 meets the requirements for adhesion, temperature and humidity of MIL-M-13508C. Quantum's gold coatings have an excellent space-flight heritage and were given the ultimate accolade in 2007 when selected for the reflective optics of the James Webb Space Telescope (JWST). Custom options are available for special substrate materials and far infrared applications.
