DLC is the best combination for optics protection and performance

unsurpassed surface protection combined with excellent infrared transmittance

Diamond-Like Carbon coating is the coating of choice for all optical applications. A single layer of Diamond-Like Carbon gives the perfect combination of protective properties coupled with good anti-reflective performance.
DLC coatings are designed to withstand corrosion, abrasion, scratch, sand, salt, oil. This rugged optical coating is perfect for optics used on military vehicles and outdoor cameras.
The unique coating process of CoolDiamond DLC enables to coat on every surface, from glass to Germanium and Silicon, polycarbonate and even chalcogenide.
DLC coating offers a high refractive index and throughout the infrared wavelength region in which it is employed, DLC exhibits moderate absorption and scattering. DLC coating is the best coating on the market for low-light applications such as night-vision googles, sensors or other IR.

Examples of applications:

  • Infra red optics
  • Optical windows
  • Thermal cameras


Mission critical parts and components perform at their maximum when coated with CoolDiamond DLC®. This is the best solution for any application where a protection from high velocity airborne particles, seawater, engine fuel and oils, high humidity etc. is needed.


CoolDiamond DLC® offers many advantages when used on engine parts: increased lifetime and abrasion prevention. The low friction coefficient of DLC improves the lifespan of engine parts and can also help reduce the amount of lubrication needed on parts & threads.


CoolDiamond DLC® is adapted for the toughest conditions and it is the logical choice for working in space conditions. In partnership with Defence SA, we are taking part in the South Australian Space Capability Directory . This directory provides a clear view of South Australia’s space economy & opportunities.
