Our ITO coatings are a perfect solution when glass with an electrically conductive surface and high optical transmission is required. We achieve these properties by sputter deposition of a thin indium tin oxide film onto high-quality glass substrates. ITO glass (TCO)Conductive ITO glass is used in almost all LCD or touch screens and often forms the anode in OLED displays. Indium tin oxide is ideal for manufacturing transparent electrodes, integrated invisible flat antennas in mobile devices, antistatic glass, heating, antifog, and de-icing windows, organic solar cells, and many other applications.

An interesting property of indium tin oxide coatings with low electrical resistance is their high reflectivity in the infrared range, which allows them to be used as IR mirrors or filters while remaining transmissive in the visible range. Furthermore, conductive glass can shield electromagnetic fields. Many of our CEC materials are ideal for the production of EM shielding glasses that can attenuate electromagnetic radio waves.

We manufacture microscope slides and cover glasses based on the glass types listed in the table on this page in all standard laboratory formats for science and research. Regardless of whether you need small parts for microscopy or large sheets for photovoltaic research, many sizes are possible. Our conductive coated glass is also an excellent solution for micro-structuring or patterning applications. Patterning can be done with a laser or by etching. We are pleased to provide typical etching recommendations on request.

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 TCO, so the conductive layer remains on top and is only in direct contact with the high-purity quartz layer, not with the soda-lime glass. This so-called passivation prevents the otherwise occurring leaching of alkali oxides from soda-lime glass into the liquid crystals of a display, which is essential to the longevity of LCDs and a significant benefit for most electronics applications. The thin SiO2 barrier improves the performance of ITO glass products nearly without increasing cost, as the deposition of this layer is efficiently integrated into the deposition process. The protection against alkali oxides achieved with the SiO2 passivation layer is superior to any other technology.

In addition to the popular S-series and P-series coated on selected HQ float glass, we produce many other conductive glasses based on more exotic substrates. 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 coated CEC-SD are part of our extensive manufacturing program. The large number of materials listed in the table are usually available from stock.

We offer solutions with customized layer thicknesses, on special glasses, or with an electrical conductivity not listed in the table. Moreover, an anti-reflective coating can be applied to the rear side in a separate production batch. Customization to your specific requirements is available on request for sufficiently large quantities. Please use our inquiry form to let us know your exact requirements. We will be happy to provide you with a corresponding 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 materials listed in the table can be quickly produced to your size specification, even for larger quantities. 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 custom sizes can be even faster with our 48-hour express option. Whether you need small 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 possible.

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

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 substrates are deposited in a smaller chamber. Therefore, the exact layer thicknesses aren't a process-controlled parameter for these materials. We only control the surface resistivity and the transmissivity of these coatings. These coatings are therefore marked “n/a” in the corresponding column of the table.

Contacting ITO glass
For contacting, you can use spring contacts, suitable silver paint, or our copper tape.
