Abstract:
An optical lens coloring system, comprising an optical lens holding device, a coloring agent discharging device having one or more nozzles for discharging coloring agent, a relative position control device operably connected to relatively position the optical lens holding device and the coloring agent discharging device, wherein the relative position control device relatively positions the optical lens holding device and the coloring agent discharging device so that coloring agent discharged out of the coloring agent discharging device is discharged in a direction substantially normal to a predetermined plane of an optical lens held by the optical lens holding device, wherein each of said one or more nozzles has a discharge opening opening substantially to one plane, and wherein said relative position control device controls the relative position of said optical lens holding device and said coloring agent discharging device by causing said optical lens holding device to make a rotary motion, oscillating motion or biaxial horizontal motion, and causing said coloring agent discharging device to make a vertical motion.
