Lens unit, lens assembly, camera module, method of fabricating camera module and lens assembly, method of fabricating optic member, and apparatus of fabricating optic member

A camera module comprising:

• a first lens unit comprising a first stack protrusion or a first stack recess;
• and
• a second lens unit coupled to the first lens unit by a second stack recess or a second stack protrusion respectively corresponding to the first stack protrusion or the first stack recess,
• wherein a side surface of a first supporting portion of the first lens unit comprises a flat cutting plane and a curved surface.

A method of fabricating a camera module, the method comprising:

• forming a first lens array substrate comprising a plurality of first stack protrusions or first stack recesses;
• forming a second lens array substrate comprising second stack recesses or second stack protrusions respectively corresponding to the first stack protrusions or the first stack recesses;
• coupling the first lens array substrate to the second lens array substrate by the first stack protrusions and the second stack recesses, or by the first stack recesses and the second stack protrusions;
• and
• dicing the first lens array substrate and the second lens array substrate,
• wherein the forming of the first lens array substrate comprises:
• injecting a photo-curable resin composition into a mold die;
• and
• irradiating light onto the photo-curable resin composition while a pressure is applied to the photo-curable resin composition,
• wherein the first lens array substrate comprises a plurality of first lens units, each having a curved surface, and a plurality of through holes is formed around the first lens units.

An apparatus of fabricating a lens unit, the apparatus comprising:

• a mold die in which a portion or whole thereof is transparent and an inside thereof is sealed;
• a light emitting device irradiating light inside the mold die;
• and
• a pressure holder increasing an internal pressure of the mold die,
• wherein the mold die comprises:
• a first mold die having an opened upper portion;
• a second mold die on the first mold die, and the second mold die covering the first mold die;
• first cores inside the first mold die;
• and
• second cores under the second mold die, the second cores corresponding to the first cores.
