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

Transparent and conductive ITO-coatings on glassIndium tin oxide coatings provide excellent optical transmission. They work in touch screens, LCDs, displays in digital devices, and form the anode of most organic LEDs (OLED). Furthermore, they 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. Besides, indium tin oxide films with low resistance are reflective in the upper infrared wavelength range. They can also work as IR mirrors and FIR filters in the infrared spectrum. Furthermore, conductive indium tin oxide coatings can shield electromagnetic fields. Due to their low electrical surface resistivities, many of our ITO coatings are an ideal solution for constructing EM protection windows that must transmit visible light and shield electromagnetic radio waves.

Our company supplies ITO-coated slides and coverslips based on the coatings listed in the table on this page in any standard laboratory size for scientific applications. So whether you use the formats, such as typical in microscopy, or whether you need ITO glass sheets with particular dimensions for photovoltaic research, all this is possible. Our ITO-coated products have also proven to be an excellent solution for micro-structuring and patterning applications. You can structure our ITO-glass by laser or etching technology. On request, we are pleased to share the etching recommendations for our indium tin oxide coatings.

All CTO coatings (CTO = conductive transparent oxide) of our CEC-S and CEC-P series feature a SiO2 passivation layer. This quartz barrier layer is only a few nanometers thick. It is located between the glass substrate and the indium tin oxide thin film so that ITO remains the top layer and is only in direct contact with the high purity quartz layer and not with the substrate glasses. 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 not only 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 layer is superior to any other technology or coating process lacking a barrier layer.

Besides the popular S- and P-series, we fabricate a wide range of other indium tin oxide coatings based on more exotic glass types. 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 side ITO-coated CEC-SD are also part of our manufacturing program. This wide range of our standard indium tin oxide coatings is usually always in stock. (see table on this website for specifications and deliverable thicknesses)

However, if you search for ITO-coatings with customized film thicknesses based on different glass types or surface resistivities not listed in the table, we also coat 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 use our coating inquiry form to contact us with your specifications and get a custom ITO-coated glass 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 coatings listed in the table can be fabricated according to your size specification rapidly, even if larger quantities are needed. We process all possible dimensions in less than a week with an average production load, so they usually 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 whether you search for a small ITO coated glass, as often required for small organic LED displays (OLED), whether you need larger dimensions for organic solar cells, or if you want a typical microscope slides size used in science. All these sizes are possible.

Film thickness specifications
We control the thickness of the ITO-layer of all CEC–S, CEC–P, and CEC–SD coatings with an in-situ process. We make all other more exotic coatings in 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 coatings. Therefore these coatings 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 coatings. You might wish to add our conductive adhesive copper tape to your ITO glass order.
