IMAGING OPTICAL SYSTEM, IMAGE CAPTURE DEVICE, AND CAMERA SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18202560 titled 'IMAGING OPTICAL SYSTEM, IMAGE CAPTURE DEVICE, AND CAMERA SYSTEM
Simplified Explanation
The patent application describes an imaging optical system that consists of three lens groups, with the second lens group being movable for focusing.
- The first lens group and the third lens group are fixed along the optical axis, while the second lens group moves during focusing.
- The first lens group is composed of a sub-lens group G1A, an aperture stop, and a sub-lens group G1B.
- The sub-lens group G1A includes three meniscus lenses: L1A1 with positive power and a convex surface facing the object, L1A2 with negative power and a convex surface facing the object, and L1A3 with negative power and a convex surface facing the object.
Original Abstract Submitted
An imaging optical system consists of a first lens group having positive power, a second lens group having power; and a third lens group having power. The first lens group and the third lens group are immobile along an optical axis and the second lens group moves along the optical axis while the imaging optical system is focusing. The first lens group consists of: a sub-lens group G1A; an aperture stop; and a sub-lens group G1B. The sub-lens group G1A includes: a meniscus lens L1A1 having positive power and having a convex surface facing the object; a meniscus lens L1A2 having negative power and having a convex surface facing the object; and a meniscus lens L1A3 having negative power and having a convex surface facing the object.
