A coating system (10) for coating an optical substrate has an identification apparatus (40) configured for identifying an orientation of at least one mark on a surface of the optical substrate; a coating apparatus (30) configured to apply at least one coating material on at least a portion of the optical substrate in a predetermined pattern by a controlled deposition of the at least one coating material in an atomized droplet form; and a robotic placement arm (80) configured to move the optical substrate from the identification apparatus (40) to the coating apparatus (30) and position the optical substrate at a predetermined orientation relative to the coating apparatus (30) based on the orientation of the at least one mark. The coating system (10) may have a second coating apparatus, such as a spin coating apparatus.
