Abstract

The invention provides an image sampling lens system, an image sampling device and an electronic device. The image sampling lens system sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from the object side to the image side. The first lens has a positive refractive power, and the object-side surface of the first lens is a convex surface. The second lens has a negative refractive power. The third lens has a refractive power, and both the object-side surface and image-side surface of the third lens are aspheric surfaces. The fourth lens has a negative refractive power, and both the object-side surface and image-side surface of the fourth lens are aspheric surfaces. The fifth lens has a refractive power, and both the object-side surface and image-side surface of the fifth lens are aspheric surfaces. The sixth lens has a refractive power, and the object-side surface of the sixth lens is a concave surface. The image-side surface of the sixth lens is a convex surface. Both the object-side surface and image-side surface of the sixth lens are aspheric surfaces. In the foregoing configuration condition, the converging ability of the whole system is focused on the object-side end of the lens, and the volume of the system can be effectively controlled. Therefore, the carrying convenience is improved. In addition, the chromatic aberration of the system and the peripheral focusing positions of an image are corrected. At the same time, the bending of peripheral images is avoided.

Description

technical field [0001] The present invention relates to an imaging lens system and an image capturing device, in particular to an imaging lens system and an image capturing device applicable to electronic devices. Background technique [0002] With the gradual thinning of personal electronic products, the internal components of electronic products are required to have a smaller size. Under the market trend, the size of the imaging lens system must be miniaturized. In addition to the requirement of miniaturization, the pixel area of ​​the photosensitive element is reduced due to the advancement of semiconductor process technology, and the imaging lens is gradually developing into the field of high pixel. At the same time, the rise of electronic devices such as smart phones and tablet computers also increases the demand for high-quality micro-image pickup lens systems. [0003] At present, most of the lenses equipped with portable electronic products on the market pursue the...
