Our high-performance Transparent Conductive Oxide (TCO) thin-film coatings—including ITO, FTO, and AZO—are engineered to deliver the perfect balance of maximum visible light transmittance ($>80\% - 88\%$) and precise sheet resistance ($10 - 100\ \Omega/\text{sq}$). Deposited via advanced magnetron sputtering and CVD technologies, these coatings transform standard glass into active electrical interfaces ideal for touch panels, transparent heaters, EMI shielding, and photovoltaic research.
Fully customizable designs with custom sheet resistance down to $< 5\ \Omega/\text{sq}$, optimized UV/VIS/NIR wavelengths, and patterned TCO options. Seamless application across Fused Silica, Quartz, Borosilicate, Sapphire, and Silicon Wafers.
Transparent conductive coating is a thin-film process that creates an electrically conductive surface while maintaining high optical transmission through the substrate. The most common transparent conductive oxide films include indium tin oxide (ITO), fluorine-doped tin oxide (FTO), and aluminum-doped zinc oxide (AZO). These coatings are typically deposited by magnetron sputtering, chemical vapor deposition, spray pyrolysis, or other thin-film coating methods, depending on the material, substrate temperature limit, conductivity requirement, and optical performance target. Transparent conductive coatings are widely used when a glass or optical window must function as both a light-transmitting component and an electrical interface, such as in touch panels, transparent electrodes, display modules, optical sensors, heated windows, EMI shielding windows, and electro-optic devices.

Custom Specifications & Inspection
Transparent conductive coatings can be customized according to sheet resistance, visible transmittance, film thickness, substrate size, coating area, pattern geometry, contact pad layout, busbar material, surface roughness, and post-deposition annealing conditions. For device-level requirements, conductive coatings can be combined with photolithographic patterning, laser ablation, wet etching, metal contact deposition, AR coating, dicing, drilling, polishing, and optical cleaning. Inspection options include four-point probe sheet resistance measurement, multi-point resistance mapping, UV-VIS-NIR transmittance testing, haze inspection, adhesion testing, microscopic defect review, line-width measurement for patterned designs, and packaging in cleanroom-compatible trays or vacuum-sealed bags.
