Bus Bars & Optics
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.
