Indium Tin Oxide (ITO) Transparent Conductive Coatings

ITO transparent conductive coatings are available from Valley Design in part sizes from a few millimeters to 450mm diameter (18"), with conductivity from 20 to 500 ohms per square. Ultra-thin wafers may also be provided.

ITO or Indium Oxide that has been doped with Tin, is widely used as a transparent conductive coating because of its electrical conductivity and optical transparency. Thin films of ITO may be deposited onto various glass substrates by physical vapor deposition such as electron beam evaporation or sputtering deposition techniques. Indium Tin Oxide coatings are used for applications where high visible light transmission and electrically conductive surfaces are required. Such applications include display windows, flat panel displays, plasma displays and touch panels among others.

Typical substrate materials are:

  • Fused Silica
  • Float Glass
  • D263 Glass
  • Eagle 2000 Glass
  • Borosilicate Glass
  • BK7 Glass
  • Sapphire

Valley can also provide these optical substrate materials in standard and custom sizes ranging from 1” diameter to 450mm diameter and all ranges of thickness. Many materials are in stock . Parts may be lapped, polished, coated and CNC machined by Valley. Contact us for any ITO coatings requirements.
