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.
Our conductive transparent ITO coatings offer an excellent optical transmission. They are often the basis for touch screens as well as for organic LEDs (OLED) and LCD displays in digital devices. And there are many more applications for our ITO coated materials. 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 in a wide range of other applications. Indium tin oxide coated glass can also be used as an infrared mirror, because ITO coatings with low surface resistivity are reflective for higher IR wavelengths. So also far-infrared filters can be based on ITO-coated glass.
Besides, 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 protection windows, which must be able to pass visible light and shield electromagnetic radio waves. For scientific and development applications such as microstructuring or photovoltaic research, we manufacture ITO-coated glass slides and cover glasses based on the ITO coatings listed in the table on this data sheet in any size commonly used in science. Of course, special dimensions are also possible.
All CTO coatings (CTO=conductive transparent oxides) of our CEC-S and CEC-P series feature a SiO2 passivation layer. This quartz barrier layer, 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 a soda-lime glass substrate 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 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 series), ITO coated borosilicate glass (CEC-B series), ITO coated 1737F glass (CEC-A series), ITO coated EAGLE2000 glass (CEC-E series), ITO coated thin glass (CEC-T series), and our new double side coated CEC-SD ITO glass. These are our standard ITO coatings usually always available (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 resistivities not listed in the table, we also offer customization 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 have deliberately not limited ourselves 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 coatings. No matter whether the ITO coated glass product you search for has a size of only some millimeters, as often 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.
