Description

Technical field [0001] The present invention relates to an optical lens group for imaging, an imaging device and an electronic device, in particular to an optical lens group for imaging and an imaging device suitable for electronic devices. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for micro-capturing modules has increased. With the advancement of semiconductor technology, the pixel size of photosensitive elements has been reduced. In addition, today's electronic products are highly functional and thin. Short appearance is the development trend. Therefore, miniaturized photographic lenses with good image quality have become the mainstream in the current market. [0003] In recent years, high-end mobile devices such as high-end smart phones, wearable devices, and tablet computers have developed toward the direction of lighter and thinner, which has also driven the requirements for miniaturization of c...
