Our EMI grids are fully customizable and thoroughly tested.

Microfabrication of Metallic Mesh Coatings

Battelle is the industry leader in designing and applying high quality, high-performance mesh coatings on visible and infrared windows and domes. 

Applications

Our metallic mesh coatings provide key advantages over ITO (Indium-Tin-Oxide) and wire grids, including high infrared and optical transmission. We use photolithography to define patterns and electron beam deposition to apply metal coatings to substrate surfaces.  

Our patterned mesh coatings are typically designed for:
  • Electromagnetic Interference shielding (please link this to the EMI Shielding paragraph further down)
  • Heating (defogging/deicing)
  • LO Properties
