20090310223 | TAKING LENS UNIT - A camera lens unit includes a first lens including a first lens section having a first optical axis along which light runs, and a second lens. The second lens includes a second lens section having a second optical axis along which the light runs, a flange provided on an outer circumference of the second lens and having a surface facing the first lens, and a cylindrical section having an inner circumference extending from the flange along the second optical axis. The inner circumference of the cylindrical section faces the second lens section. The first lens contacts the inner circumference of the cylindrical section of the second lens and is engaged into the cylindrical section. The cylindrical section of the second lens includes plural protrusions protruding along the second optical axis, such that plural crenels are provided between the protrusions and have heights along the second optical axis lower than the protrusions. The camera lens unit prevents diffuse reflection caused by unnecessary incident light. | 12-17-2009 |
20100309367 | IMAGING LENS AND IMAGING DEVICE USING THE SAME - The present invention provides an imaging lens composed of four lenses that can be made compact (downsized, thinned), allows a reduction in cost and is compatible with a high pixel imaging element having a megapixel or more incorporated in a small mobile product such as a mobile phone. The imaging lens | 12-09-2010 |
20100328518 | IMAGING LENS AND IMAGING DEVICE USING THE LENS - The present invention provides an imaging lens composed of three lenses that can be made compact (downsized, thinned), allows a reduction in cost and can be made compatible with a high pixel imaging element having a megapixel or more incorporated in a small mobile product such as a mobile phone. The imaging lens | 12-30-2010 |
20110019281 | IMAGING OPTICAL SYSTEM AND IMAGING DEVICE USING THE SAME - An imaging optical system capable of sufficiently suppressing the occurrence of flare or ghost that degrade the image quality is provided. The imaging optical system is an imaging optical system | 01-27-2011 |
20120019706 | IMAGE PICKUP LENS AND IMAGE PICKUP DEVICE USING THE SAME - An image pickup lens capable of providing an angle of view of up to 70° or higher is provided. The image pickup lens can also be reduced in size and various aberrations associated with the lens can be corrected favorably, so that the image pickup lens is compatible with a high-pixel image pickup element. The image pickup lens | 01-26-2012 |
20120224080 | IMAGE PICKUP LENS, IMAGE PICKUP DEVICE USING SAME, AND PORTABLE DEVICE EQUIPPED WITH THE IMAGE PICKUP DEVICE - The present invention provides an image pickup lens capable of adequately suppressing flare caused by unnecessary diffraction order light. An image pickup lens | 09-06-2012 |
20120229695 | IMAGE PICKUP LENS, IMAGE PICKUP DEVICE USING SAME, AND PORTABLE DEVICE EQUIPPED WITH IMAGE PICKUP DEVICE - An image pickup lens compatible with small high-pixel image pickup elements (e.g., from CCD and CMOS image sensors having a pixel pitch of 1.75 μm and a pixel count of 5 mega pixels to CCD and CMOS image sensors having a pixel pitch of 1.4 μm and a pixel count of 8 mega pixels) is provided. An image pickup lens | 09-13-2012 |
20120307135 | IMAGE PICKUP LENS, IMAGE PICKUP DEVICE USING SAME, AND PORTABLE APPARATUS EQUIPPED WITH THE IMAGE PICKUP DEVICE - The present invention provides an image pickup lens with a large focal depth from the center to the outer part of an image plane formed on an image sensor and capable of maintaining its focal depth within a practical range and thus suppressing a decline in the resolution. An image pickup lens | 12-06-2012 |
20120314122 | PLASTIC LENS, PHOTOGRAPHING LENS, IMAGING DEVICE, AND PORTABLE DEVICE - A plastic lens includes a flange portion on an outer circumference of a lens effective-diameter portion and manufactured by injecting a resin into a mold via a gate portion. The plastic lens is characterized by having a shape satisfying conditions of s/t≦0.61 and E.D/D≧0.4 when s [mm] and t [mm] represent a peripheral thickness, a central thickness of the lens effective-diameter portion, E.D [mm] represents a lens effective diameter, and D [mm] represents a lens diameter. | 12-13-2012 |
20140347515 | IMAGING LENS AND IMAGING DEVICE USING SAME - An imaging lens includes, arranged in sequence from the object side to the imaging surface side, a first lens having a positive power and convex surfaces on both sides; an aperture diaphragm; a second lens being a meniscus lens having a negative power and a convex surface on the object side; a third lens being a meniscus lens having a positive power and a concave surface on the object side; and a fourth lens having a negative power and concave surfaces on both sides. With this structure, the imaging lens is well corrected for various aberrations in spite of being compact in the lens radial direction and thin in the optical axis direction. | 11-27-2014 |
