Abstract

The invention discloses an optical lens group for imaging, an image capturing device and an electronic device. The optical lens group for imaging sequentially includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side. The object side surface, close to the optical axis, of the first lens is a concave surface. The second lens has positive refractive power. The object side surface, close to the optical axis, of the third lens is a convex surface, and the image side surface close to the optical axis is a concave surface. The image side surface, close to the optical axis, of the sixth lens is a concave surface. The image side surface of the sixth lens has at least one inflection point. The total number of lenses of theoptical lens group for imaging is six, and the dispersion coefficients of at least two lenses are smaller than 30. The invention also discloses the image capturing device provided with the optical lens group for imaging and the electronic device provided with the image capturing device.

Description

technical field [0001] The invention relates to an optical lens group for imaging, an image pickup device and an electronic device, in particular to an optical lens group for imaging and an image pickup device suitable for electronic devices. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature imaging modules has increased day by day, and with the advancement of semiconductor technology, the pixel size of photosensitive elements has been reduced. The short and small appearance is the development trend, therefore, miniaturized photographic lenses with good imaging quality have become the mainstream in the current market. [0003] Due to the prevalence of high-end smart phones, wearable devices, tablet computers, driving recorders, aerial cameras and image recognition systems and other electronic devices that need to obtain large-scale images in recent years, the demand for wide viewing angl...
