Description

Dual lens for personal mobile communication and electronic camera

The present invention relates to a dual composite lens for a personal mobile communication device and an electronic device camera, and more particularly, to a dual lens provided with a hard contact lens in a personal mobile communication device and an electronic device camera, and is basically provided in a portable device. The present invention relates to a dual composite lens for a personal mobile communication device and an electronic camera, which reinforces the photographing function of a CMOS and CCD camera equipped with a dual lens and enables high-quality photographing of an SLR class by replacing a double composite lens.

Recently, with the development and demand of DSLR cameras, the public's interest in photography has increased, and as the user's interest and utilization of cameras mounted on personal mobile communication devices or other small electronic devices increases, The technology of camera lenses mounted on the field is also developing.

On the other hand, the image pixel problem, which has been pointed out as a disadvantage of the camera lens mounted on the personal mobile communication device or other small electronic device, has been approached to 8 million and 10 million pixels, which is comparable to that of the existing DSLR as the technology is developed. It is still difficult to achieve the various photographing effects obtained by variously replacing the camera lens with a wide angle, fisheye, bundle, macro lens, and the like.

DSLR camera can take various pictures by overcoming the limited environment such as distance, close, light and low by changing the lens. The lens is classified into single lens and zoom lens according to focal length. According to the field of view, it is divided into a wide-angle lens, a standard lens, a telephoto lens and the like.

In this case, the focal length indicates the distance of the lens from the CCD (CMOS) corresponding to the film of the camera. The shorter focal length lens has a wider angle of view, and the longer the lens in the CCD (CMOS), the narrower the angle of view.

The focal length indicates the type of lens according to the angle of view: fisheye lens (7-15mm), wide-angle lens (15-35mm), standard lens (38-58mm), telephoto lens (70-200mm), super telephoto lens (200mm or more) And the like.

First, the standard lens is a lens almost similar to that of the human eye, with an angle of view of 40 to 60 degrees and a focal length of 50 mm.

Next, the wide-angle lens has a wide angle of view of 60 degrees or more and a focal length of 50 mm or less, so that the wide-angle range is wider than that of the standard lens, so that the wide-angle lens is widely used for landscape photography or indoor interior photography that makes a narrow space look wider.

Next, the telephoto lens is a lens that pulls up a distance of 40 degrees or less and a focal length of 50 mm or more.

In addition, one of the wide-angle lenses includes a fisheye lens having an angle of view of 180 degrees or more, a macro lens used for a close-up, a reflective telephoto lens using a concave mirror principle, a reflective telephoto lens, a soft focus lens, and a shift lens.

Such lenses include a macro lens, a standard lens, a wide-angle lens, a telephoto lens, etc. having different focus magnifications, and generally, a lens suitable for a macro, short-range, medium-distance, and long-distance may be combined to form a group.

First, the lens group 140 used for the dual composite lens 100 as a lens for a personal mobile communication device and an electronic device camera may be configured as a hard contact optical lens to reduce the size and volume.

The hard contact type optical lens refers to a hard contact type lens that corrects an angle of view of a camera of a portable device, which is not for vision correction, and functions as a macro, fisheye, and telephoto.

In addition, the material and molding method of the lens is selected from the group consisting of glycol carbonate, Cellulose Acetate Butylate (CAB) copolymer, poly methyl methacrylate (PMMA), and a silicone-containing hydrophobic polymer. Any one or more of the selected contact lens materials may be molded through a cast molding die casting.

Referring to the manufacturing method of the lens group 140 used in the present invention. However, the present invention does not limit the manufacturing method of the lens group.

First, an optical design of a hard contact lens having diopters D according to spherical refraction and prism refractive index is made of oxygen-impermeable material having high refractive index, which does not transmit oxygen due to the characteristics of the hard contact lens.

Next, the optically designed product shape can be processed by the first and second injection mold methods.

In the injection mold, after attaching the mold to the injection molding machine, the molten resin is filled in the mold cavity of the product shape (hard contact lens) at an appropriate pressure and speed, and the solidified resin is cooled and solidified for a predetermined time. It is intended to produce molded products (hard contact lenses).

At this time, the molded part on the moving side among the designed metallic shape parts such as a molded article (hard contact lens) may be called a core, and the name of the molded part on the fixed side may be called a cavity.

The product shape can be processed in a toric shape of the optical design by using nickel copper as the material of the injection mold core according to the workability examination based on the optical design.

Meanwhile, the mold core may perform roughing, primary finishing and secondary finishing using a three-dimensional high speed machine (22,000 RPM) to effectively perform complex edge machining of toric and offset spherical surfaces.

In addition, the processed lens injection core may have a processing tolerance of PV 0.2 탆, surface roughness (roughness) Ra 10 nm or less, required for the core surface.

Next, the injection molding of the lens using the casting molding (Cast Molding) can be performed.

In this case, the injection molding material is selected from the group consisting of glycol carbonate, Cellulose Acetate Butylate (CAB) copolymer, polymethyl methacrylate (PMMA), and a silicone-containing hydrophobic polymer. One or more hard contact lens materials may be molded through a cast molding die casting, plasticizing the hard contact lens materials, and filling the plasticized melted resin into a mold through a molding machine nozzle and cooling. It can solidify and take out.

Next, the taken out lens can be surface treated by a post-processing operation such as polishing.

Lenses manufactured by the above method are inserted into through-holes arranged circularly at regular intervals from the centers of the first rotating plate 110 and the second rotating plate 120 of the present invention, and thus the first lens group 140a. Or it may be composed of a second lens group 140b. (See Figure 3)

On the other hand, the diameter of the lens group and the diopter (D) can be produced in various ways according to the performance of the lens, the manufactured lenses are arranged in a circular arrangement of the first rotating plate 110 and the second rotating plate 120 of the present invention An apparatus for insertion into a through hole may include a barrel 141 that is equally standardized to accommodate the manufactured lenses.

In this case, the bonding agent for the bonding may be a nano-adhesive material such as an acrylic polymer or Geckle or a bonding agent having a predetermined adhesive strength.

Next, the barrel 141 to which the manufactured lenses are bonded is inserted and fastened appropriately in consideration of being configured as a double compound lens in the holes of the first lens group 140a and the second lens group 140b.

In this case, as described above, the fixing of the lens to the rotating plate through the barrel is only an example, and the present invention is not limited to the fixing method, and directly attaches the manufactured lens to the rotating plate through the bonding agent. It is possible.

For example, as shown in FIG. 2B, the lens group 10 attached to the dual composite lens attaches the lens 11 to one surface of the plate 12 having a predetermined thickness d, and the other surface of the plate. The bonded body 13 can be included in the above, and the bonded body can be attached to the rotating plate 14. Preferably, the plate has a thickness of about 1 mm. As described above, the rotating plate may include a through hole smaller than the diameter of the plate, and the through hole may bond the plate to an upper portion thereof. Alternatively, the plate may be bonded to the rotating plate without a through hole, and in this case, the rotating plate is preferably made of a transparent material.
