OPTICAL LENS COMBINATION AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/177416
Kind Code:
A1
Abstract:
An optical lens combination and an imaging device. The optical lens combination from an object side to an image side sequentially comprises a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), and a sixth lens (L6). The first lens is a meniscus lens having negative optical power, and an object side surface (S1) of the first lens is a convex surface, and an image side surface (S2) is a concave surface. The second lens has negative optical power, and an image side surface (S4) of the second lens is a concave surface. The third lens is a meniscus lens having positive optical power, an object side surface (S5) of the third lens is a concave surface, and an image side surface (S6) is a convex surface. The fifth lens is glued with the fourth lens. The sixth lens has a positive optical power. By means of the optical lens combination and the imaging device, high resolution can be obtained while the optical lens combination is kept miniature.
