Imaging lens, imaging device, portable terminal, and method for manufacturing imaging lens
Abstract:
An imaging lens (LN) includes at least three lens blocks (BK), and an aperture stop (ape). The lens block (BK) includes parallel flat lens substrates (LS) formed of different materials, and a lens (L). In the imaging lens (LN), the object side lens surface of a first lens (L1) included in a first lens block (BK1) is a surface protruding to the object side, the object side lens surface of a third lens (L3) included in a second lens block (BK2) is a surface recessed from the object side, and at least the object side lens surface of a fifth lens (L5) or the object side lens surface of a sixth lens (L6) included in a third lens block (BK3) is aspherical.
Abstract(Chinese):

成像透镜（LN）包括至少三个透镜块（BK）和孔径光阑（ape）。 透镜块（BK）包括由不同材料形成的平行平面透镜基板（LS）和透镜（L）。 在成像透镜（LN）中，包括在第一透镜块（BK1）中的第一透镜（L1）的物体侧透镜表面是向物体侧突出的表面，第三透镜​​（L3）的物体侧透镜表面 包括在第二透镜块（BK2）中的是从物体侧凹陷的表面，并且至少第五透镜（L5）的物体侧透镜表面或第六透镜（L6）的物体侧透镜表面包括在第三透镜 透镜块（BK3）是非球面的。
