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.
Our ITO coatings provide excellent optical transmission. They are used for touch screens as well as for organic LEDs (OLED) and LCD-displays in digital devices and represent a perfect solution 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. Furthermore, indium tin oxide coated glass can be used as a coating for infrared mirrors because ITO coatings with low surface resistance provide good reflection in the higher IR wavelength range, so we can also manufacture far-infrared filters based on ITO coatings due to their infrared reflective properties. Conductive transparent indium tin oxide coatings are also 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 micro-structuring, patterning applications, 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, also customer-specific dimensions are possible.
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, 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 additional SiO2 coating process increases product quality without increasing cost, as it is integrated efficiently into the coating process of our CEC-S and CEC-P ITO-glass series.
In addition to the popular S- and P-type of ITO coatings, we fabricate 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. This wide range of our standard coatings usually is 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 can do 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.

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, 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 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 range. 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. |
