OPTICAL SYSTEM AND IMAGE PICKUP APPARATUS HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18507149 titled 'OPTICAL SYSTEM AND IMAGE PICKUP APPARATUS HAVING THE SAME
The optical system described in the patent application consists of a front group, an aperture stop, and a rear group with positive refractive power. The front group includes a lens with negative refractive power closest to the object, while the rear group includes a final lens with positive refractive power closest to the image plane. There are four or more lenses between the first and final lenses, with a lens surface near the optical axis of the final lens having a meniscus shape with a convex surface on the object side, satisfying predetermined inequalities.
- Front group with a lens having negative refractive power closest to the object

Original Abstract Submitted
An optical system includes, in order from an object side to an image side, a front group, an aperture stop, and a rear group that has positive refractive power as a whole. The front group includes a first lens having negative refractive power disposed closest to an object. The rear group includes a final lens having positive refractive power disposed closest to an image plane. The optical system includes four or more lenses disposed between the first lens and the final lens. A lens surface near an optical axis of the final lens has a meniscus shape with a convex surface on the object side. Predetermined inequalities are satisfied.
