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.
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.
