Anti-Fog for LCDs

The transparent conductive coating in an optical heater is primarily comprised of different conductivities of indium tin oxide (ITO). The ITO can be dielectrically enhanced (index matched) to improve reflection and transmission properties in the desired optical performance band (e.g., visible spectrum, near IR). By index matching reflection losses are converted to transmitted light. Dontech can index match the conductive coatings to air (n=1), to the optical substrate, and to an optical adhesive (n=1.43 through n>2.36). Standard conductivities for ITO coatings range from 250 ohms/sq. Applications include avionic displays, vehicle displays, mobile computers, kiosks, and handheld devices.
