The invention relates to a wide-angle lens, an imaging module, an electronic device and a driving device. The wide-angle lens sequentially comprises, from an object side to an image side along an optical axis: a first lens with negative refractive power, wherein the object side surface of the first lens is a convex surface near the optical axis, and the image side surface of the first lens is a concave surface near the optical axis; a second lens element with negative refractive power and having a concave object-side surface; a third lens element with positive refractive power; a fourth lens element with negative refractive power and having a concave image-side surface; a fifth lens element with positive refractive power and having a convex object-side surface; a sixth lens element with positive refractive power; and a diaphragm which is arranged on the object side of the sixth lens. When the wide-angle lens satisfies a specific relationship, the wide-angle lens can be miniaturized while having a wide viewing angle and a high resolution capability, and the imaging quality of the wide-angle lens is less affected by the ambient temperature.
本申请涉及一种广角镜头、成像模组、电子装置及驾驶装置。广角镜头沿着光轴由物侧至像侧依序包括具有负屈折力的第一透镜,其物侧面近光轴处为凸面,像侧面近光轴处为凹面;具有负屈折力的第二透镜,其物侧面为凹面;具有正屈折力的第三透镜;具有负屈折力的第四透镜,其像侧面为凹面;具有正屈折力的第五透镜,其物侧面为凸面;具有正屈折力的第六透镜;以及光阑,设于所述第六透镜的物侧。上述广角镜头在满足特定关系时,能够在具备广视角以及高解像能力的同时兼顾小型化,且其成像品质受环境温度的影响较小。
