The ITO-coatings of our CEC-serie are used whenever an electrically conductive surface that at the same time offers a high optical transparency is needed. Transparent and conductive ITO-coating coated on glass slidesThis is achieved by sputter-coating a thin conductive layer of indium-tin-oxide on high quality glass substrates. Our 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 many other unique technical appliances in science. For research and development applications, we manufacture ITO-coated microscope slides and cover slips at any common size, used in science. Indium-tin-oxide has the capability to shield electromagnetic fields. Because of the low electrical sheet resistances we have available, our ITO-coatings therefore are often used for EM-shielding applications, while still transmitting most of the visible light.

The conductive transparent oxide coatings (CTO coatings) of our CEC-S and CEC-P series feature a SiO2 passivation layer. This quartz barrier layer 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, which is a basic requirement for most liquid-crystal-displays (LCD). Furthermore, it is advantageous for most other electronic applications. The additional coating process was efficiently integrated into the production and does not increase cost.

In addition to our S- and P-type 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) and our new double side coated CEC-SD. These are our standard ITO-coated products (see table on the right). But we also offer custom ITO-coating services, so the manufacturing of ITO-coatings can be customized to your requirements. Substrate material, optical transmission, conductivity, passivation layer, the layer thickness of the indium tin oxide layer 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 or use our coating-inquiry-form to request a quote your customized ITO-coating.

 

Standard Product Dimensions

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 ship within less than a week, which is as quick as it is usually for stock items with fixed dimensions. No matter whether the ITO-coated glass you search has a size of only some millimeters or you need substantially larger dimensions, as often required for display applications, or whether you need the typical dimensions of microscope slides used in science, all these sizes are possible.
