The ITO coatings of our CEC series are used wherever a glass with an electrically conductive surface and high optical transparency is required. These properties are obtained by sputter-coating a thin conductive indium tin oxide layer onto a high-quality glass substrate.

Transparent and conductive ITO-coatings on glass slidesOur conductive transparent ITO-glass materials offer a high optical transmission are often found in LCD-displays, touchscreens, and micro-structuring processes. However, there are many more applications for our ITO-coatings. They are used for the manufacturing of transparent electrodes, integrated invisible flat antennas, anti-static windows, heating and de-icing windows with an optical function, infrared mirrors, organic LED (OLED) displays, and for various other unique technical applications in industry, science, and research.

Indium-tin-oxide coated materials offer the capability to shield electromagnetic fields. Because of the low electrical surface resistances we have available, many of our ITO-coatings can be used as EM-shielding windows which must be capable of passing visible light. For research and development applications, we manufacture ITO coated slides and cover glasses based on the materials listed in the table in any size commonly used in science. Nevertheless, also custom dimensions are possible.

The conductive, transparent oxide coatings (CTO coatings) of our CEC-S and CEC-P materials feature a SiO2 passivation layer. This quartz barrier-coating, which is only a few nanometers thick, is coated between the glass substrate and the indium tin oxide coating. The passivation layer provides high electrical insulation and minimizes the possible leaching of alkali oxides from the glass substrate material into liquid crystals. This feature is an essential requirement for the longevity of liquid crystal displays (LCD) and is advantageous for various other applications not only in electronics. This additional SiO2 coating process increases quality while it does not add any additional cost, as it is integrated efficiently into the production process of our ITO-coated glass.

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), and our new double side coated ITO-glass CEC-SD. These are our standard ITO-coated glass products (see table on this website).

However, if you search for ITO-glass with other film thicknesses, substrate material or surface resistance, we also offer customized ITO-coatings according to your requirements. We can adapt the glass material, optical transmission, electrical conductivity, the passivation layer, layer thickness of the indium tin oxide coatings, and other technical properties to your technical specifications in a separate coating run. Also, backside anti-reflection coatings are optionally possible for some of our ITO-coated materials per coating run. Please contact us for detailed information about our custom coating services or use our coating inquiry form to request a quote for your customized ITO-coatings.


Standard Dimensions

Since almost every application requires an individual part size, we deliberately waived to be restricted to standard dimensions. Most of our indium tin oxide coatings listed in the chart can be manufactured according to your custom size specification within a short delivery time even in large quantities. With average production load, we produce all possible part sizes in less than a week, so they can usually be delivered just as quickly as stock items with fixed dimensions. No matter whether the ITO-coated glass product you search for has a size of only some millimeters, as required for small organic LED displays, whether you need substantially larger dimensions, or if you need the typical size of microscope slides used in science, all these dimensions are possible.
