Abstract
The present invention provides a method for manufacturing a lens used in a camera module including the steps of: preparing a preform for manufacturing a lens; forming a front lens on a front surface of the preform; and forming an array lens by forming a rear lens on a rear surface of the preform during the formation of the front lens.
Claims12
A method for manufacturing a lens used in a camera module comprising:
- preparing a preform for manufacturing a lens;
- forming front lenses on a front surface of the preform;
- and
- forming an array lens by forming rear lenses on a rear surface of the preform during the formation of the front lenses,
- wherein preparing the preform for manufacturing the lens comprises forming a preliminary front lens portion of a shape corresponding to that of the front lenses, on a front surface of a material for manufacturing a lens, and forming a preliminary rear lens portion of a shape corresponding to that of the rear lenses, on a rear surface of the material for manufacturing the lens,
- wherein forming the front lenses comprises preparing a first stamp having a front lens forming portion of a shape corresponding to that of the front lenses, and pressing the first stamp on the front surface of the preform in a state in which the front lens forming portion faces the front surface of the preform, and
- wherein forming the rear lenses comprises preparing a second stamp having a rear lens forming portion of a shape corresponding to that of the rear lenses, and pressing the second stamp on the rear surface of the preform in a state in which the rear lens forming portion faces the rear surface of the preform.
