Laser Gold Substrates

Laser Gold is usually applied over metal substrates including, but not limited to, aluminum, beryllium, copper, stainless, molybdenum, titanium. Non-metallic substrates such as Zerodur, silicon, quartz, BK7 etc. can also achieve the durability and reflectivity of Laser Gold by first applying a binder coating (usually chromium) by sputtering or vacuum deposition (see specification plating and substrates).
