The ITO-coatings of our CEC-serie are used whenever an electrically conductive surface with a high optical transparency is needed. These properties are obtained by sputter-coating a thin conductive layer of indium-tin-oxide on high quality glass substrates.

Transparent and conductive ITO-coatings on glass slidesOur conductive, transparent ITO-glass is often used for LCD-displays, touch screens and micro structuring applications. But there are many other typical applications for our ITO-coatings. They are used for the manufacturing of transparent electrodes, as integrated invisible flat antennas, antistatic windows, heating and de-icing windows with an optical function, far infrared range mirrors and for many other unique technical appliances in industry and science.

Indium-tin-oxide coatings have the capability to shield electromagnetic fields. Because of the low electrical surface resistances we have available, our ITO-coatings can be used for EM-shielding windows, which must be capable to transmit visible light. For research and development applications, we manufacture ITO-coated microscope slides and cover slips at any common size, used in science. But also custom sizes are possible.

The conductive, transparent oxide coatings (CTO coatings) of our CEC-S and CEC-P series feature a SiO2 passivation layer. This quartz barrier-coating is only a few nanometers thick and is located between the glass substrate and the indium-tin-oxide-coating. This layer offers an increased electrical insulation and minimizes possible leaching of alkali-oxides from the glass into liquid crystals. This is a basic requirement for most liquid-crystal-displays (LCD) and it is advantageous for various other electronic applications. The additional coating process does not increase cost, as it is efficiently integrated into the production cof the coatings.

In addition to our popular S- and P-type of ITO-coatings, we manufacture ITO-coated quartz glass (CEC-Q), ITO-coated borosilicate glass (CEC-B), ITO-coated 1737F glass (CEC-A), ITO-coated EAGLE2000 glass (CEC-E), ITO-coated thin glass (CEC-T) as well as our new double side coated CEC-SD. These are our ITO-coated standard products (see table on this website).

But we also offer custom ITO-coating services. So, the manufacturing of ITO-coatings can be customized to your requirements. Substrate material, optical transmission, the electrical conductivity, passivation layer, the layer thickness of the indium tin oxide coatings and other technical properties can be adapted to your technical requirements in a separate coating run. Please contact us for detailed information about our custom coating services and use our coating inquiry form to request a quote your customized ITO-coatings.

 

Standard Sizes

Since almost every application requires an individual part size, we deliberately waived to be restricted by standard sizes. Most of our ITO-coatings listed in the chart, can be manufactured according to your custom size specification within a short lead time, even at large quantities. At normal production load, any possible part size will be manufactured within less than a week so they are supplied just as quick as it is usually for stock items with fixed dimensions. No matter whether the ITO-coated glass you search for has a size of only some millimeters or whether you need substantially larger dimensions, as it is often the case for displays, or if you need the typical dimensions of the microscope slides used in science, all dimensions are possible.
