Transparent Conductive Coatings
Custom Indium Tin Oxide & Index-Matched Indium Tin Oxide (ITO/IMITO) coatings for photonics. Optimized for durability & index matched for transmittance in excess of 98%. Optional glare reducing broadband & laser line anti-reflective properties.
Bus Bars
A bus bar is a strip of conductive material applied to the surface of a conductively coated glass, most commonly ITO (indium tin oxide) or IMITO (index matched ITO) coatings. Bus bars are screen printed onto an exposed surface of the coated glass; Abrisa applies bus bars either by thin film deposition of chrome-nickel-gold or by screen printing. The conductive nature of these materials makes them excellent bus bars. The primary function of a bus bar is to conduct electricity. Typical bus bar applications for optics include heater windows and EMI Shielding. In the case of IMITO coatings, we need to expose the ITO so that the bus bar can be applied directly to the conductive ITO coating.
EMI Shielding ITO & IMITO Coatings
Transparent conductive coatings are often used in electro-magnetic shielding, electrical heating, and cutting-edge display applications. ZC&R uses the coating material indium tin oxide (ITO) which provides for high durable coatings. Often, ITO coatings are used in contact with materials other than air. ZC&R often designs and produces ITO coatings designed specifically to be used next to materials such as liquid crystal, cements, index oils, and various other materials. ITO coatings that have been under-coated or over-coated to be index matched to a particular material such as liquid crystal can have very low reflectances. One determining factor as to how low a reflectance can be achieved is the sheet resistivity specification. Thicker ITO layers yield lower sheet resistivities but generally result in higher reflectances. Sheet resistivities as low as 5 to 10 ohms/sq and as high as a few thousand ohms/sq can be achieved. One common thickness of ITO, 100 angstroms, yields approximately 450 ohms/sq. ZC&R has a great deal of experience coating ITO and index-matched ITO and we would be happy to review any specification requirements you may have, and work with you to determine what can be achieved using ITO coatings for your particular application.
Heater Window ITO & IMITO Coatings
Abrisa Technologies’ Transparent Conductive Heaters incorporate coatings of Indium Tin Oxide (ITO), Index-Matched Indium Tin Oxide (IMITO) or Indium Molyb-denum Oxide (IMO) and are ideal window and display glass solutions when anti-fogging or de-icing, and high throughput and clarity are needed to maintain unobscured viewing and optical sensing in cold climates. The coatings deliver the high uniformity and low scatter performance needed to preserve high resolution digital imaging, sensing or display outputs while maintaining high throughput efficiency and clari-ty. Our solutions incorporate key heating attributes that can be tailored for specific needs, including design considerations for anti-reflective properties for visible, NIR, SWIR, and IR, optimization to air or index matched for bonding, and delivery of color neutral performance in transmission, reflection, or both.
