Our Indium Tin Oxide coatings are the perfect choice when glass with an electrically conductive surface and high optical transmission is required. We achieve these properties by sputter depositing a thin, conductive ITO film on high-quality glass substrates.

Transparent and conductive ITO-filmsIndium Tin Oxide coatings provide excellent optical transmission. They are used in touch screens and LCDs in digital devices or form the anode of most organic LEDs in OLED technology. In addition, ITO films are a perfect solution for manufacturing transparent electrodes, integrated invisible flat antennas in mobile communication devices, antistatic glass, heating- and anti-icing windows, organic solar cells, and a wide range of similar applications.

Another property of low-resistance ITO is its high reflectivity in the upper infrared wavelength range, which allows ITO-coated glass to be used as IR mirrors and FIR filters in the infrared spectrum. In addition, the electrically conductive indium tin oxide can shield electromagnetic fields. Many of our ITO-coated materials are ideal for constructing EM shielding windows that allow visible light to pass through while shielding electromagnetic radio waves.

Our company also fabricates ITO on microscope slides and coverslips made of the materials listed in the table on this page in any standard laboratory size for applications in science and research. Small formats typically used in microscopy or large ITO glass sheets with dimensions used in photovoltaic research are available. Our ITO-coated products are also excellent solutions for micro-structuring and patterning applications. Our ITO glass can be structured with a laser or by etching. We can provide etching recommendations for our indium tin oxide coated materials upon request.

All transparent conductive oxide coatings (TCO) in our CEC-S and CEC-P series have a SiO2 passivation layer. This quartz barrier is only a few nanometers thick. It is located between the substrate and the thin film coating of indium tin oxide, so the ITO film remains on top and is only in direct contact with the high-purity quartz layer, not the substrate glass. This passivation layer prevents the otherwise occurring leaching of alkali oxides from a soda-lime glass into the liquid crystals of a display, which is critical to the longevity of LCDs and a significant benefit for most electronics applications. The SiO2 layer improves product performance without increasing cost, as the coating of this layer is efficiently integrated into the coating process. The perfect alkali-ion shielding performance achieved with the SiO2 barrier is superior to any other technology.

In addition to the popular S-series and P-series, we produce many other indium tin oxide coatings based on more exotic glasses. ITO-coated optical 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 double-sided ITO-coated CEC-SD are also part of our manufacturing program. This wide range of our standard indium tin oxide coated glass is usually always in stock. (See the table on this web page for specs and possible thicknesses.)

We also have a solution if you need an ITO coating with custom film thicknesses or based on other substrate materials or surface resistances not listed in the table. We can 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. Please use our inquiry form to contact us with your requirements for a quote.

 

Standard Sizes

Since almost every application requires a specific part size, we have deliberately not limited our product range to a few fixed sizes. Most of our indium tin oxide materials listed in the table can be quickly produced to your size specification, even if larger quantities are required. We typically process all possible dimensions in less than a week, so they are often shipped as quickly as stock items with fixed dimensions. Delivery time for these custom sizes is even faster with our 48-hour express service, available upon request for an additional charge. Whether you need small ITO-coated glass parts commonly used for organic LED displays (OLED), require larger dimensions for organic solar cells, or want a typical microscope slide size used in science, all these sizes are available.

Customization
A custom film thickness, substrate material, glass thickness (≥ 0.175 mm), surface resistance (5 Ω-1 kΩ), or backside anti-reflective coatings are possible per production batch upon request. Don't hesitate to contact us for more details about our ITO coating deposition services.

Film thickness
We control the film thickness of all CEC-S, CEC-P, and CEC-SD coatings with an in-situ process. All other, more exotic materials are deposited using a smaller coater. Therefore, the film thickness isn't a process-controlled parameter for these materials. We only control the surface resistivity and the transmissivity of these coatings. Thus, these products show "n/a" in the table's "typical ITO film thickness" column.

Contacting ITO-coated glass
To contact our ITO-coated materials, you can use spring contacts, suitable conductive silver paint, or our conductive adhesive copper tape.
