Advanced Optical and Materials Coating

Proprietary Magnetron Sputter Deposition System and Process

Technology

Novel Coating System Producing Precision Coating on Polymers and Other Difficult Substrate Types and Shapes

Nanohmics has developed a custom Magnetron Sputter tool that produces robust, radiation-hard, optical coatings, primarily for polymeric Fresnel lenses and specialized infrared optics though numerous applications exist.

Key Benefits

  • Low stress deposition
  • Uniform sputtering on complex shapes
  • Improved optical performance
  • Ability to coat polymers, metals, optics, and a host of other materials

Market Impact

Current commercial coating systems have difficulty producing high grade coatings without cracking and adhesion problems.

Nanohmics has developed a lab scaled deposition system and proprietary process for creating low stress, crack-free optical quality coatings on a variety of substrates, including polymers such as acrylics and polycarbonate..

Market Demand

NASA and optics makers are actively seeking a solution to the problem of optical coating of polymers. The ability would allow the production of lighter weight optics than glass, lowering expense of launch as well as cost of optic manufacturing.

Numerous optical component makers are interested in robust coatings providing reflective, anti-reflective, or bandpass features.  These coatings can be placed on items ranging from ophthalmic lenses to IR laser cavity optics.

Markets

Markets that can benefit from the unique deposition capability include:

  • Optics
  • Tooling
  • Ceramics
