Abstract

The invention relates to an optical lens. The invention discloses an optical imaging lens, which sequentially includes a diaphragm, a first, a second, a third and a fourth lens along an optical axis from the object side to the image side, and each lens has an object side and an image side; The optical lens meets TTL / T4≦6.7 and ALT / T3≦3.6. The present invention also discloses an electronic device, which includes a casing, and an imaging device installed in the casing including an optical imaging lens as described above, a lens barrel, a module rear seat unit, a substrate and an image sensor module. The invention is used for optical photography.

Description

Optical imaging lens and electronic device using the optical imaging lens technical field The invention relates to an optical lens, in particular to an optical imaging lens and an electronic device using the optical imaging lens. Background technique In recent years, the popularization of portable electronic products such as mobile phones and digital cameras has led to the vigorous development of imaging module related technologies. The imaging module mainly includes components such as optical imaging lens, module holder unit and sensor. The thin and light trend of digital cameras also makes the miniaturization of image modules more and more demanding. For CMOS) technological progress and size reduction, the length of the optical lens loaded in the image module also needs to be shortened accordingly, but in order to avoid the decline of photographic effect and quality, good optical performance must still be taken into account when shortening the length of the optical lens....
