Diamond-Like Carbon (DLC) coating is an amorphous nano-composite carbon material that exhibits properties similar to that of natural diamond including low friction, high hardness, and high corrosion resistance.
Because of its Infrared (IR) optical and durability properties DLC is used in optical industry where extarnal optical components require anti-reflaction and durability to withstand the harshest environments (thermal cameras, optical windows, and infrared optics).
IZOVAC has developed and successfully uses the efficient method of forming diamond-like protective optical antireflection coatings (DLC coatings) on germanium and silicon substrates. Such optical coatings sufficiently increase mechanical strength of the products as well as transmission coefficient. The method is based on sputtering graphite targets and destruction of hydrocarbons in gas discharge plasma (PECVD) with subsequent ion beam formation, resulting in formation of quaziamorphous diamond-like films.
Optics parts with deposited DLC coatings have passed all environmental tests and optical mechanical evaluations, established for coatings of such class.
DLC coating by PECVD is realized in DIAMANTA product.
