DLC Сoating by PECVD

Diamond-Like Carbon (DLC) coating is an amorphous nano-composite carbon material coating 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 the optical industry where external optical components require anti-reflection and durability to withstand the harshest environments (thermal cameras, optical windows, and infrared optics).

I-Photonics has developed and successfully uses an efficient PECVD process for forming diamond-like protective optical anti-reflection coatings on germanium and silicon substrates. This method, known as plasma enhanced chemical vapor deposition, significantly increases the mechanical strength and transmission coefficient of the products. The PECVD system works by sputtering graphite targets and decomposing hydrocarbons in a gas discharge plasma, which then leads to the formation of quasi-amorphous diamond-like films.

Optics parts with deposited DLC coatings by PECVD are passing all environmental tests and optical mechanical evaluations established for coatings of this type.

The DLC deposition by PECVD is realized in  the DIAMANTA product line.
