TRANSPARENT SUBSTRATE HAVING AN ANTI-REFLECTIVE MULTILAYERED COATING THEREON AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A transparent substrate with an anti-reflective coating layer and a manufacturing method thereof are provided to increase transmissivity in a visible ray and near-infrared ray wavelength range and to decrease the transmissivity in a far-infrared ray wavelength range. CONSTITUTION: A first coating layer is formed on a transparent base material with a first refractive index. A second coating layer is formed on the first coating layer with a second refractive index. A third coating layer is formed on the second coating layer with a third refractive index. A fourth coating layer is formed on the third coating layer with a fourth refractive index. The first and third refractive indexes are greater than the second and fourth refractive indexes.
