ZOOM LENS, IMAGE PICKUP APPARATUS, AND IMAGE PICKUP SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18507143 titled 'ZOOM LENS, IMAGE PICKUP APPARATUS, AND IMAGE PICKUP SYSTEM
Simplified Explanation
The patent application describes a zoom lens with specific lens units that change position during zooming, maintaining image quality.
- The zoom lens consists of a first lens unit with positive refractive power, a second lens unit with negative refractive power, a third lens unit with positive refractive power, and a rear group.
- The distance between lens units changes during zooming from wide-angle to telephoto.
- The first lens unit remains fixed relative to the image plane during zooming.
- The first lens unit includes a single lens with negative refractive power closest to the object and multiple lenses with positive refractive powers on the image side.
- An air lens is formed by an air gap between the single lens and the adjacent lens on the image side.
- The design satisfies a predetermined inequality to ensure optimal performance.

Original Abstract Submitted
A zoom lens includes, in order from an object side to an image side, a first lens unit having positive refractive power, a second lens unit having negative refractive power, a third lens unit having positive refractive power, and a rear group. A distance between adjacent lens units changes during zooming from a wide-angle end to a telephoto end. The first lens unit is fixed relative to an image plane during zooming from the wide-angle end to the telephoto end. The first lens unit includes single lens having negative refractive power closest to an object, and a plurality of lenses having positive refractive powers disposed on the image side of the single lens. An air lens is formed by an air gap between the single lens and a lens adjacent to and disposed on the image side of the single lens. A predetermined inequality is satisfied.
