Abstract
The method for coating plural surfaces on multiple sides of a substrate, especially a lens, includes launching microwave outputs into a microwave reactor at respective microwave launch sites; selecting respective microwave outputs to be greater than or equal to thresholds at which corresponding plasmas having a reduced permeability to microwave radiation arise in the microwave reactor; setting distances between the plural surfaces and microwave launch sites greater than microwave penetrations depths in the plasmas; placing respective dielectric tuning elements in microwave fields formed from the microwave outputs at the launch sites; and adapting the shapes of the dielectric tuning elements to the plural surfaces to be coated, so that plasma inhomogeneities are corrected and coatings with a uniformity of ±1% are formed on the plural surfaces.
