Our ITO coatings are a perfect choice when glass with an electrically conductive surface and high optical transparency is required. We achieve these properties by sputter coating a thin indium tin oxide film onto high-quality glass substrates. Transparent and conductive ITO glassITO coatings on glass are used in touch screens and LCDs, or form the anode in OLED displays. Furthermore, ITO is excellently suited for the production of transparent electrodes, integrated invisible flat antennas in mobile communication devices, antistatic glass, heating and demisting/defrosting windows, organic solar cells, and many similar use cases.

Another interesting property of ITO coatings with low electrical resistance is their high reflection in the upper infrared wavelength range, allowing them to be used as IR-reflective optics or FIR filters. Furthermore, electrically conductive indium tin oxide films can shield electromagnetic fields. Many of our CEC materials are ideal for the production of EM shielding glasses that can transmit visible light and attenuate electromagnetic radio waves at the same time.

Our company also fabricates ITO-coated microscope slides and coverslips from the glasses listed in the table on this page in any standard laboratory size for use in science and research. Regardless of whether you need small parts for microscopy or large panels for photovoltaic research, many sizes are possible. Our ITO coatings are also excellent solutions for micro-structuring and patterning applications, which can be done with a laser or by etching. We are pleased to provide typical etching recommendations on request.

All transparent conductive oxides (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 ITO coating, so the conductive film remains on top and is only in direct contact with the high-purity quartz, not with the soda-lime glass. This passivation prevents the otherwise occurring leaching of alkali oxides from 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 thin SiO2 barrier improves the performance of an ITO-coated product 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 coated on float glass, we produce many other coatings based on more exotic substrate materials. ITO-coated optical grade quartz (CEC-Q), borosilicate glass (CEC-B), alkali-free 1737F (CEC-A), EAGLE2000 (CEC-E), thin glass (CEC-T), and our double-sided ITO-coated CEC-SD are part of our extensive manufacturing program. Our large selection of coatings is usually always in stock. (See the table on this web page for specs and possible thicknesses.)

We also offer solutions for ITO coatings with customized layer thicknesses, on special substrate materials, or with an electrical conductivity not listed in the table. We can coat to your requirements in a custom coating run. The same applies to index-matched ITO or anti-reflection coatings on the backside, which is possible for some materials. Please use our inquiry to submit your requirements so we can work up a quote for you for your custom ITO coating.

 

Custom 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 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 can often ship as quickly as stock items with fixed dimensions. Delivery time for these custom sizes is even faster with our 48-hour express option. Whether you need small ITO-coated parts for your organic LED displays (OLED), require larger dimensions for solar cells, or want a typical microscope slide size used in science, all these sizes are available.

Customization
A custom ITO film thickness, glass material, glass thickness (≥ 0.175 mm), conductivity (3.5 Ω - 1 kΩ/sq.), or backside anti-reflective coating is possible per batch upon request. Don't hesitate to contact us for more details.

Film thickness
We control the ITO 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 coating line. Therefore, the exact 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 coatings show “n/a” in the table's “typical ITO film THK” column.

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