Abstract
The present invention relates to an optical element that includes a mark (). The optical element has a first coating layer () over at least a portion of a surface of an optical substrate () having the mark () on the surface of the optical substrate, and one or more additional coating layers () over at least a portion of the first coating layer (). The first coating layer has a first refractive index, and the optical substrate and the mark may have a second refractive index. A difference between the first refractive index and the second refractive index has an absolute value of 0.02 to 0.24. At least one of the first coating layer () and the one or more additional coating layers () may be applied by a controlled deposition of a coating material in droplet form.
