摘要： Present embodiments provide for an optical imaging lens. The optical imaging lens may comprise four lens elements positioned sequentially from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may exhibit better optical characteristics and the total length of the optical imaging lens may be shortened.

摘要： Present embodiments provide for an optical imaging lens. The optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least two inequalities, the optical imaging lens shows better optical characteristics, increases the effective focal length and narrows the angle of view while the total length of the optical imaging lens is shortened.

摘要： An optical lens assembly includes first, second, third and fourth lens elements arranged in sequence from an object side to an image side along an optical axis. Each lens element has an object-side surface and an image-side surface. The first lens element has positive refracting power, and the image-side surface of the first lens element has a convex portion in a vicinity of the optical axis and a convex portion in a vicinity of a periphery. The second lens element has negative refracting power. The object-side surface of the third lens element has a concave portion in a vicinity of the periphery. The image-side surface of the fourth lens element has a convex portion in a vicinity of the periphery.

摘要： Present embodiments provide for ocular optical systems. An ocular optical system for imaging of imaging rays entering an eye of an observer via the ocular optical system and a pupil of the eye of the observer from a display screen, may comprise four lens elements positioned sequentially from an eye side to a display side. By controlling the refracting power and the surface shape of the lens elements and designing parameters satisfying at least one inequality, the ocular optical system may exhibit better optical characteristics and the half field of view of the ocular optical system may be broadened.
