Typical transmission of one OCF2520 Sheet. Please note that the data given is typical, and performance may vary slightly from lot to lot.

Thorlabs' OCF2520 is a pack of twenty optically clear, Polyethylene Terephthalate (PET) Film Sheets that have a conductive Indium Tin Oxide (ITO) coating deposited on one side. The coating has a sheet resistance of 350 to 500 Ω/sq*, and each sheet is highly flexible and temperature resistant up to 120 ºC.

Measuring 250 mm x 200 mm x 0.2 mm (L x W x T) in size, our ITO-coated PET sheets provide high transmission in the 400 nm - 2110 nm spectral range. Please see the transmission plot to the right for details. The film has a surface quality of 40-20 scratch-dig on the ITO coated side and 60-40 scratch-dig on the uncoated side.

Each sheet is protected on both sides by a thin film that can be pulled off using the included red tabs. A multimeter can be used to verify the side with the conductive ITO coating.

Applications
ITO-coated PET films can be used in a number of different applications due to their high optical transmission and conductivity. They can be used in liquid crystal devices to provide a transparent, conductive layer that accepts the applied voltage used to realign the liquid crystal cells. The sheets are also commonly used as components for touchscreens, position sensors, electroluminescent lamps, and electrophoretic displays, as well as in electromagnetic shielding applications. 

*Sheet Resistance
Sheet resistance is defined as ρ/t: the resistivity (Ω*m) divided by the thickness (m) of the conductive ITO coating. The units are given as Ω/sq (Ohms per square) to differentiate the sheet resistance from the total resistance of some area of the film. The resistance of these films is given by:

R = Rs * (L/W)

where L and W are the length and width of the film, respectively, and Rs is the sheet resistance. For a square of the thin film, where L = W, the resistance of the film is equal to the sheet resistance regardless of size.

I just wanted to know that what material is used to make the protective covering that comes on the top of ITO sheet

What is the crystallinity of the ITO film (amorphous, poly crystalline, etc.)? I would like etch these films but I have read that etch rate is determined by the crystallinity of the ITO thin film. Thank you for your time.

Thank you for contacting Thorlabs. ITO is a non-crystalline (amorphous) film.

Hello, what is the seed layer in the coating material? Does this affect overall conductivity of the ITO ?
YLohia  (posted 2020-07-06 09:23:48.0)
Hello, thank you for contacting Thorlabs. Our ITO films do not have seed layers.

Hello, is this product suitable for creating resistive touch-screens? Thank you.

Hello, thank you for contacting Thorlabs. ITO coated PET Films have been used in flexible screen and touchscreen applications. If you have further questions, please feel free to email your local Thorlabs Tech Support team regarding this.

would you have this as a thinner film, e.g. 50 µm thick in total with a sub-micron ITO layer on top of it? Would you also be able to supply this with Polycarbonate as the substrate in place of PET?

Response from Meike at Thorlabs: Thank you for contacting us! There is some possibility for customization, but it will depend on the required quantities and specifications. Since you opted not to be contacted, please reach out to europe@thorlabs.com in case you would like to discuss this further.

Hi, would it be possible to get an exact resistance of 10 ohm/sq for the ITO sheets as well as the RMS roughness of the ITO. Thanks!
YLohia  (posted 2020-03-12 08:26:30.0)
Hello, thank you for contacting Thorlabs. We have reached out to you directly to discuss this further.

Hello, is there a maximum power input to the ITO heater? Max W/cm2? Thanks!
YLohia  (posted 2018-06-01 08:29:21.0)
Hello, we have yet to perform damage threshold testing on these units so, unfortunately, we don't have any recommendations at the moment for the maximum power density that this ITO heater can handle.

Hi, Would it be possible to have the thickness of ITO and PET on this film ? Thanks!
tfrisch  (posted 2016-11-01 10:41:08.0)
Hello, thank you for contacting Thorlabs. Each is about 75um. The remaining thickness would be adhesive, about 50um.
