The ITO-coatings from our CEC series are used wherever a glass with an electrically conductive surface with high optical transparency is required. We achieve these properties by sputter coating a thin conductive indium tin oxide layer to a high-quality glass substrate.

Transparent and conductive ITO-coatings on glass slidesOur conductive transparent ITO-glass materials offer excellent optical transmission. They are often the basis of touchscreens as well as organic LEDs (OLED) and LCD displays. And there are many more applications for our ITO-coatings. They are used, for example, for the manufacturing of transparent electrodes, integrated invisible flat antennas in mobile communication devices, anti-static glass, heating and de-icing windows, and similar. Indium-tin-oxide coated glass can also be used as an infrared reflector because ITO-coatings with low surface resistivity reflects the higher IR-wavelengths efficiently. Moreover, there are various other interesting technical applications for ITO-coated glass in industry, science, research, and development.

Indium-tin-oxide coatings offer the capability of shielding electromagnetic fields. Due to the available low electrical surface resistances, many of our ITO-coatings can be used as EM-shielding windows which must be capable to pass through visible light. For scientific and development applications such as microstructuring or photovoltaics research, we manufacture ITO-coated slides and cover glasses based on ITO-coatings listed in the table on this spec-sheet in any size commonly used in science. However, also custom dimensions are of course possible.

All CTO coatings (CTO = conductive, transparent oxide) of our CEC-S and CEC-P material feature a SiO2 passivation layer. This quartz barrier coating, which is only a few nanometers thick, is located between the glass substrate and the indium-tin-oxide thin film. 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. The additional SiO2 coating process increases quality without adding any 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 CEC-SD ITO-glass. These are our standard ITO-coatings (see table on this website for details about these products).

However, if you search for ITO-coatings with other film thicknesses or based on other substrate materials or surface resistances not listed in the table, we also offer customized ITO-coatings according to your requirements. We can use other glass materials and adapt the optical transmission, electrical conductivity, the passivation layer, layer thickness of the indium tin oxide coatings and other technical properties to your required specifications in a separate coating run. Also, you can order backside anti-reflection coatings which 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 table 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. In particularly urgent cases, our 48h express service is also available for an extra charge for most of our ITO glasses. 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 (OLED), whether you need substantially larger dimensions, or if you need the typical size of microscope slides used in science, all these sizes are possible.
