CLAREX® AR & EMI SHIELD COAT FILTER

CLAREX® EMI SHIELDING FILTER has a high transmission special conductive membrane exhibiting excellent electro-magnetic shielding performance.
There are four types of Clarex
EMI Shielding Filters.

CLAREX® AR & EMI COAT FILTER is treated with a multi-layer AR coating and ITO coating which prevents light reflection and shield EMI respectively. Additional coatings prevent surface scratching and smudging.
CLAREX® AR COAT FILTER may be combined with non-glare surface to improve anti-reflection.


FEATURES:


  • Excellent electro-magnetic shielding performance.
  • High transmission.
  • Excellent optical characteristics.
  • Excellent surface hardness.
  • Excellent smudge resistance.
  • Excellent impact resistance.
  • Available with anti-reflective coating for maximum light transmission and minimum light reflection.

Available in any colour. (see standard colours)
