Opco - Indium Tin Oxide (ITO) Coatings
Indium tin oxide (ITO) coatings demonstrate high transparency and electrical conductivity. They are ideal for use on optical components that require excellent light transmissivity in the visible to near-infrared range. ITO-hybrid coatings combine the properties of standard ITO and other optical coatings. At OPCO, we offer ITO and ITO-hybrid coatings that accommodate sheet resistivity requirements ranging from 10 to 1,000 ohms per square for most glass and polymer substrates.
They are suitable for light ranging from 0.4 to 2.5µm in wavelength. As ITO coatings allow for excellent electrical conductivity without inhibiting light transmission, they are commonly used for electronic components such as touchscreens, organic LEDs, and digital displays. Other examples of applications for these coatings include:
- Anti-fog windows vehicles and displays
- Electrically conductive electromagnetic interference (EMI) shielding
- Electrostatic control devices
- Heated windows for microscopy
- OLEDs, solar cells, and other semiconductor components
- On/off light blocking smart windows
OPCO produces ITO (Indium-Tin-Oxide) and other ITO-hybrid transparent conductive coating designs.
These films are typically used for applications that demand high visible light transmission and an electrically conductive surface.
OPCO’s transparent conductive coatings are deposited to customer specified sheet resistance, transmission, or coating thickness on various substrates.
The resistivity can be specified from 10 to 1,000 ohms per square on most substrates.
