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 coatings provide excellent optical transmission. They are often the basis for touch screens as well as for organic LEDs (OLED) and LCD displays in digital devices. But 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, as anti-static glass, heating and de-icing windows, and in a wide range of similar applications. Indium tin oxide coated glass can also be used as an infrared mirror, as ITO coatings with low surface resistance are reflective for longer 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 low electrical surface resistances available, many of our coatings can be used as EM protection windows that must pass through visible light and shield electromagnetic radio waves. For scientific applications like micro-structuring or photovoltaic research, we manufacture ITO-coated slides and cover glasses based on the coatings listed in the table on this page in any size commonly used in science. Of course, specific 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, which is only a few nanometers thick, is located between the glass substrate and the indium tin oxide thin film, so that the ITO coating remains the top layer. It minimizes the possible leaching of alkali oxides from a soda-lime glass 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 coatings usually always available (see table on this website for details about these products).

However, if you search for ITO-coatings with different film thicknesses or based on other glass materials or surface resistivities not listed in the table, we also offer customization to your requirements. We can can custom coat almost any 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 deposition run. You can also order rear anti-reflection coatings, which are optional for some of our ITO coated materials based on at least one coating batch. To get a quote for a custom coating, please use our coating inquiry form.

 

Standard Dimensions

Since almost every application requires a special part size, we have deliberately not limited our product range 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 if larger quantities are needed. 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.
