Inventors include Liu, Yuyi; and Zhou, Shunda.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention relates to the field of optical lenses. Disclosed is an imaging optical lens, comprising eight lenses in total, the eight lenses being, sequentially from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens, wherein a focal length of the third lens is defined as f3, a focal length of the fourth lens is defined as f4, a focal length of the seventh lens is defined as f7, a focal length of the eighth lens is defined as f8, a central radius of curvature of an image-side surface of the seventh lens is defined as R14, a central radius of curvature of an object-side surface of the eighth lens is defined as R15, the total optical length of the imaging optical lens is defined as TTL, and an on-axis distance from an image-side surface of the eighth lens to an image surface is defined as BF, satisfying the following relational expressions: 2.00=f3/f4=8.00, -0.40=f7/R14-f8/R15=-0.10, and 0.12=BF/TTL=0.15.
