ITO coatings from our CEC series are used wherever a glass with an electrically conductive surface and 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 ITO coatings provide excellent optical transmission. Hence, they are often the basis for touch screens as well as for organic LEDs (OLED) and LCD-displays in digital devices. However, there are many more applications for our ITO coatings. They are perfect for the manufacturing of transparent electrodes, integrated invisible flat antennas in mobile communication devices, as anti-static glass, heating- and de-icing windows, organic solar cells, and for a wide range of similar applications. Indium tin oxide coated glass can also be used as infrared mirrors because ITO coatings with low surface resistance are reflective in the higher IR wavelength range. So also far-infrared filters can be based on ITO-coated glass.

Besides, conductive transparent indium tin oxide coatings are capable of shielding electromagnetic fields. Due to the low electrical surface resistances available, many of our coatings are an ideal solution for 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 thin quartz barrier coating layer, which is only a few nanometers thick. It is located between the glass substrate and the indium tin oxide thin-film coating so that ITO remains the top layer and is only in direct contact with the quartz coating and not with the substrate glasses. It prevents the normal leaching of alkali oxides from a soda-lime glass substrate into liquid crystals. This feature is crucial for the longevity of liquid crystal displays (LCD) and is advantageous for various other applications, not only in electronics. This SiO2 coating process increases quality without adding cost, as it is integrated efficiently into the coating 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 coating. These are our standard coatings usually always available (see table on this website for details about these coatings).

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 custom coat most 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, rear side anti-reflection coatings and index-matched ITO coatings are optionally possible for some materials based on at least one coating batch. To get a quote for a custom coating process, please use our coating inquiry form to contact us with your specifications.


Standard Dimensions

Since almost every application requires a particular part size, we have deliberately not limited our products to a few standard dimensions. Most of our indium tin oxide coatings listed in the table can be fabricated according to your custom size specification within a short time, even if larger quantities are needed. With average production load, we process all possible dimensions in less than a week, so they can usually be shipped just as quickly as stock items with fixed dimensions. In particularly urgent cases for an extra charge, our 48h express service is also available 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.

Other indium tin oxide film-thickness or ITO-surface resistivity (5 Ω-1 kΩ), custom glass thicknesses (≥ 0,1 mm), different substrate materials, or backside anti-reflection coatings on a batch basis are available per request. Please contact us for further details about our custom ITO coating services.

We control the thickness of the ITO-films of all CEC–S, CEC–P, and CEC–SD coatings with an in-situ process. We make all other more exotic coatings in a smaller coating machine. Hence, the film-thickness isn't a process-controlled parameter for these materials. We only control the surface resistivity and the transmissivity of those coatings in the visible. Therefore these coatings show "n/a" in the typical film-thickness table column.

For contacting our ITO coatings, you can use spring contacts, suitable conductive silver paint, or our adhesive copper tape. You might wish to add our conductive adhesive copper tape to your ITO glass order.
