20090040626 | Subminature imaging optical system - There is provided a subminiature imaging optical system subminiature imaging optical system including: a first lens element having a convex object-side surface; a second lens element having an object-side surface in contact with an image-side surface of the first lens element; and a third lens element having an object-side surface in contact with an image-side surface of the second lens element, wherein the object-side surface of the first lens element and an image-side surface of the third lens element are aspherical, and the third lens element has a point of inflection formed within an effective aperture thereof such that the image-side surface is convexed toward an image plane at a central portion to have positive refractive power and concaved toward the image plane at a peripheral portion to have negative refractive power. | 02-12-2009 |
20090086339 | Subminiature optical system - There is provided a subminiature optical system mounted in a mobile communication terminal and a personal digital assistant (PDA) or used for a monitoring camera and a digital camera. The subminiature optical system includes: a first lens entirely having a positive refractive power and comprising a first lens element having an object-side surface convex toward the object on an optical axis; a second lens element having an object-side surface in contact with an image-side surface of the first lens element; and a third lens element having an object-side surface in contact with an image-side surface of the second lens element and an image-side surface concave toward an image on the optical axis; and a second lens entirely having a positive refractive power and comprising a fourth lens element having an object-side surface convex toward the object on the optical axis; and a fifth lens element having an object-side surface in contact with an image-side surface of the fourth lens element and an image-side surface formed of a plane. | 04-02-2009 |
20090147368 | Method for manufacturing wafer scale lens assembly and wafer scale lens assembly manufactured by the same - A method for manufacturing a wafer scale lens assembly, and a wafer scale lens assembly manufactured by the same are disclosed. The method includes forming a plurality of transmissive regions and a plurality of non-transmissive regions on an object-side surface or an image-side surface of each of first and second lens substrates, forming a plurality of lens elements having refractive power on at least one of the object-side surface and the image-side surface of each of the first and second lens substrates, and stacking the first and second lens substrates, with a spacer interposed between the first lens substrate and the second lens substrate. Accordingly, image quality is improved by preventing undesired light from forming an image on an image plane of an image sensor. The process time is reduced to reduce a manufacturing cost. | 06-11-2009 |
20100053772 | Lens assembly and manufacturing method of the same - There is provided a lens assembly including: a first lens part including a first lens surface as an object-side surface, a second lens surface as an image-side surface, and a peripheral part defining a periphery of the second lens surface; a second lens part disposed at an image side of the first lens part and including at least one lens; a spacer spacing the first lens part and the second lens part from each other; and a light adjustor disposed between the second lens surface and the peripheral part, the light adjustor totally reflecting or refracting light incident at a predetermined angle of view or more. | 03-04-2010 |
20120162794 | LENS MODULE - There is provided a lens module. The lens module according to the present invention may include a lens unit including one or more lenses, each having a lens function part and a flange part forming a circumference of the lens function part; and a piezoelectric body disposed on the flange part so as to shield unnecessary light incident through the lens unit and performing autofocusing according to an application of voltage thereto. | 06-28-2012 |
20130063824 | LENS MODULE AND MANUFACTURING METHOD THEREOF - There is provided a lens module including: a first lens member including an optical part and a bonding part; and an identification mark printed on the first lens member. Further, there is provided a lens module manufacturing method, the manufacturing method including: preparing a first lens member including an optical part and a bonding part; and printing and forming a light shielding film and an identification mark on the bonding part. | 03-14-2013 |
20130084353 | STAMP FOR MOLDING LENSES - There is provided a stamp for molding lenses, including: a first stamp including a plurality of first lens molding parts; and a second stamp including a plurality of second lens molding parts corresponding to the plurality of first lens molding parts, wherein the first lens molding parts have different sizes so as to mold at least two types of lens. | 04-04-2013 |
