EmiClare Sigma

Your EMI shielded display will look and perform better when fitted with an EmiClare mesh window

EmiClare mesh is in the center of this demonstration sample. Compared to the traditional mesh of the outer frame.

A display fitted with EmiClare mesh is brighter and more legible compared to traditional mesh.

This is because Optical Filters was the first and only window manufacturer to re-engineer wire woven mesh specifically for electronic displays. 

Traditional mesh windows with configurations like 100, 80 and 50 openings per inch (opi) were inherited from non optical applications like chemical and partical filtration.

A clearer picture is achieved when shielding a display with EmiClare Mesh. The unique construction & geometry of EmiClare mesh creates less distortion and moiré fringing.

EmiClare mesh is designed for electronic displays and has three major benefits;

EmiClare Sigma is the quickest and most cost effective solution for shielded windows.

Mass manufactured in state of the art clean rooms the polycarbonate laminated sheet stock is available in a range of standard thicknesses and provides the window with either a clear hard coat finish on both sides or non-glare hard coated front surface with a clear hard coating on the rear.

The key benefits to the customer are:

  • Quick prototyping and economical, small production runs
  • Short lead times and reliable deliveries
  • Cost effective EMI window solutions
  • High impact and low weight UL94 rated polycarbonate
  • All the optical and shielding performance of EmiClare Mesh

Fabrication steps


1. Pre-manufactured laminated EmiClare Sigma panel
2. Machined to final size by CNC. This may include steps, holes, complex forms etc
3. Application of the conductive busbar to terminate EmiClare mesh
4. Inspection and quality assurance before delivery
