Kind Code:
A1
Abstract:
An optical system and an imaging device comprising same, and an electronic device. The optical system comprises, from an object side to an image side, a first lens (10), a second lens (20), a third lens (30) and a fourth lens (40), which are sequentially arranged, wherein any one of the first lens (10), the second lens (20), the third lens (30) and the fourth lens (40) is a super lens, and the rest are all refractive lenses. An object side surface and an image side surface of the refractive lens in the optical system both comprise at least one aspheric surface, and the aspheric surface comprises an inflection point. The optical system satisfies f/EDP ＜ 3, 25° ≤ HFOV ≤ 65°, and 0.3 ≤ fN/f ≤ 5.5, wherein f is the focal length of the optical system, EPD is the entrance pupil aperture of the optical system, fN is the focal length of the first refractive lens from the object side to the image side of the optical system, and HFOV is half of the maximum field of view of the optical system.
