The indium tin oxide coatings of our CEC series are a perfect choice whenever a glass with an electrically conductive surface and high optical transparency is required. We achieve these properties by applying a thin conductive ITO layer to high-quality glass substrates using sputter technology.
Our indium tin oxide coatings provide excellent optical transmission. They are used for touch screens as well as for organic LEDs (OLED) and LCD-displays in digital devices. Furthermore, they represent a perfect solution for the manufacturing of transparent electrodes, integrated invisible flat antennas in mobile communication devices, anti-static glass, heating- and de-icing windows, organic solar cells, and a wide range of similar applications. Indium tin oxide coatings can also be used to make IR-mirrors and FIR-filters because ITO coatings with low surface resistance and high film thickness have a good reflection in the upper infrared wavelength range.
Conductive transparent indium tin oxide coatings can shield electromagnetic fields. Due to the low surface electrical resistances available, many of our ITO coatings are an ideal solution for the construction of EM protection windows that must transmit visible light and shield electromagnetic radio waves.
For scientific applications, we produce ITO-coated slides and coverslips based on the coatings listed in the table on this page in any standard laboratory size. So whether you use standard formats, such as the slides used in microscopy, or whether you need ITO glass in custom sizes for photovoltaic research, all these dimensions are possible. Our ITO-coated materials have also proven to be an excellent solution for micro-structuring and patterning applications. You can structure our ITO-glass by laser or etching technology. On request, we are pleased to send you the etching recommendations for our indium tin oxide coatings.
All CTO coatings (CTO = conductive transparent oxide) of our CEC-S and CEC-P series feature a SiO2 passivation layer. This quartz barrier layer, which is only a few nanometers thick. It is located between the glass substrate and the indium tin oxide thin film so that the ITO coating remains the top layer and is only in direct contact with the quartz layer and not with the substrate glasses. This passivation layer prevents the otherwise occurring leaching of alkali oxides from a soda-lime glass substrate into liquid crystals. It is crucial for the longevity of liquid crystal displays (LCD) and of great advantage for various other applications, not only in electronics. The SiO2 coating increases product quality without increasing cost, as it is integrated efficiently into the coating process. The perfect alkali-ion shielding performance achieved with the SiO2 layer is superior to any other technology or coating process without a barrier layer.
In addition to the popular S- and P-series, we fabricate a wide range of other indium tin oxide coatings based on more exotic glass materials. This includes ITO-coated quartz glass (CEC-Q), ITO coated borosilicate glass (CEC-B), 1737F ITO-glass (CEC-A), EAGLE2000 ITO-glass (CEC-E), ITO coated thin glass (CEC-T), and our new double side coated CEC-SD ITO-coating. This wide range of our standard indium tin oxide coatings is usually always available (see table on this website for specifications and available substrate thicknesses)
However, if you search for ITO-coatings with other film-thicknesses or based on custom glass materials or surface resistivities not listed in the table, we also custom-coat to your requirements in a dedicated coating run. The same applies to index-matched ITO and backside anti-reflective coatings, which are optional for some materials. 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 dimension, we have deliberately not limited our products to a few standard sizes. Most of our indium tin oxide coatings listed in the table can be fabricated according to your custom size specification rapidly, 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, our 48h express service is available for a surcharge for most of our ITO coatings.
No matter whether the ITO coated glass product you search for is small, as often required for small organic LED displays (OLED), whether you need substantially larger dimensions, or if you want a typical microscope slides size 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 these coatings. 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. |
