Light transmission, absorption and reflection are determined by the properties and the colour of the base material. The thickness of the coating is choosen in relation to the wave length in the application to guarantee the best light transmission. Standard coatings are choosen for optimum light transmission. Generally they are between 525 und 600 nm.
Typical transmission of a 20 Ohm-square coating is 84 %.
Silver busbar will be used to create a contact area from the coating to the surface of the substrate.
