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

Transparent and conductive ITO glassIndium 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 an ITO coating with low electrical resistance 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 CEC-materials are ideal for the production of EM shielding glasses that transmit visible light and attenuate electromagnetic radio waves at the same time.

Our company also fabricates ITO on microscope slides and coverslips based on the glasses listed in the table on this page in any standard laboratory size for applications in science and research. Regardless of whether you need small parts for microscopy or large panels for photovoltaic research, almost all dimensions are possible. Our ITO coatings are also excellent solutions for micro-structuring and patterning applications. They can be structured with a laser or by etching. We are pleased to provide typical etching recommendations for our indium tin oxide coatings per 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 glass and the of indium tin oxide coating, so the conductive film remains on top and is only in direct contact with the high-purity quartz, not the with the soda-lime glass. This passivation 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 the performance without increasing cost, as the deposition of this layer is efficiently integrated into the coating process. The protection against alkali ions 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), borosilicate glass (CEC-B), 1737F (CEC-A), EAGLE2000 (CEC-E), thin glass (CEC-T), and our double-sided ITO-coated CEC-SD are part of our manufacturing program. This large selection of 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, other glass material, or electrical 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 consider using our inquiry form to contact us with your requirements for a quote.

 

Customized Dimensions

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, glass material, glass thickness (≥ 0.175 mm), conductivity (5 Ω-1 kΩ/sq.), or backside anti-reflective coating is 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 thicknesses 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 thicknesses aren'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 THK” column.

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