Our indium tin oxide coatings are a perfect choice whenever glass with an electrically conductive surface and high optical transmission is required. We achieve these properties by sputter coating a thin, conductive ITO film on high-quality glass substrates.

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

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

Our company supplies ITO films deposited on slides and coverslips made of the materials listed in the table on this page in any standard laboratory size for scientific applications. Small formats typically used in microscopy or large ITO glass sheets with dimensions used for photovoltaic research are possible. Our ITO-coated products are also excellent solutions for microstructuring and patterning applications. You can structure our ITO glass with a laser or by etching. On request, we are pleased to share the etching recommendations for our indium-tin oxide-coated materials.

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

Besides the popular S- and P-series, we fabricate 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 materials is usually always in stock. (See the table on this website for specifications and deliverable thicknesses.)

We will also have a solution if you search for ITO with customized film thicknesses based on other materials or surface resistivities not listed in the table. We can coat ITO according 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 consider using our inquiry form to contact us with your specifications and get a custom ITO quote.


Standard Dimensions

Since almost every application requires a particular part dimension, we have deliberately not limited our delivery program to a few fixed sizes. Most of our indium tin oxide materials listed in the table can be rapidly fabricated according to your size specification, even if larger quantities are needed. We typically process all possible dimensions in less than a week, so they mostly ship just as quickly as stock items with fixed dimensions. The delivery time for those custom sizes is even shorter with our 48-hour express service, which we offer on demand for an additional charge.

No matter if you are searching for small ITO-coated glass parts often 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 possible.

Customized ITO film thicknesses, substrate materials, glass thicknesses (≥ 0,175 mm), surface resistivities (5 Ω – 1 kΩ), or backside anti-reflection coatings are possible per production batch on request. Don't hesitate to contact us for further details about our ITO coating deposition services.

Film thickness specifications
We control the thickness of the ITO film of all CEC–S, CEC–P, and CEC–SD materials with an in-situ process. All other, more exotic materials are deposited with 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 products. Therefore, these products show "n/a" in the "typical film thickness" table column.

Contacting ITO-coated glass
You can use spring contacts, suitable conductive silver paint, or our adhesive copper tape for contacting our ITO-coated materials. Please consider adding our conductive adhesive copper tape to your ITO glass order.
