20120200944 | IMAGING LENS - An imaging lens includes, from an object-side to an image-side: an aperture stop, a first lens of positive refractive power with two convex surfaces along the optical axis of the imaging lens, a meniscus second lens of negative refractive power with a convex surface on the object-side, a meniscus third lens of positive refractive power with a convex surface on the image-side, a meniscus fourth lens of negative refractive power with a convex surface on the object-side. Specified conditions are satisfied in order to reduce aberrations and an Fno (focal ratio number) and enhance wide-angle view. | 08-09-2012 |
20120194927 | IMAGING LENS - An imaging lens includes, from an object-side to an image-side: a first lens of positive refractive power with a convex surface on the object-side, an aperture stop, a second lens of negative refractive power with a convex surface on the image-side and a meniscus shape, a third lens of positive refractive power with a convex surface on the object-side and a meniscus shape. Specified conditions are satisfied in order to enhance a high brightness and reduce aberrations. | 08-02-2012 |
20120194925 | IMAGE PICKUP LENS - An image pickup lens includes, in sequence from an object side to an image side, an aperture stop; a first lens having two convex surfaces and having a positive refractive power; a second lens in a meniscus shape whose convex surface faces to the object side having a negative refractive power; a third lens in a meniscus shape with the convex surface facing to the image side having a positive refractive power; a fourth lens in a meniscus shape with the convex surface facing to the object side having a negative refractive power. Predefined conditions are satisfied. | 08-02-2012 |
