ZOOM LENS AND IMAGE PICKUP APPARATUS HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337820 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS HAVING THE SAME
The abstract describes a zoom lens with a first lens unit having negative refractive power followed by multiple subsequent lens units that can move to adjust the distance between them. The zoom lens also includes an aperture stop, and specific conditions must be met for the lens to function properly.
- The zoom lens consists of a first lens unit with negative refractive power and several subsequent lens units.
- The first lens unit remains fixed while the subsequent lens units can move to change the distance between them.
- An aperture stop is included in the design of the zoom lens.
- Certain predetermined conditions must be satisfied for the zoom lens to operate effectively.
Potential Applications: - Photography equipment - Surveillance systems - Medical imaging devices
Problems Solved: - Providing variable focal lengths - Ensuring image clarity and sharpness - Allowing for flexibility in capturing different scenes
Benefits: - Versatility in capturing images at various distances - Enhanced image quality - Improved control over depth of field
Commercial Applications: Title: "Innovative Zoom Lens Technology for Enhanced Imaging" This technology can be used in cameras, smartphones, drones, and other imaging devices to improve the quality and flexibility of image capture. The market implications include increased demand for high-quality imaging equipment in various industries.
Questions about Zoom Lens Technology: 1. How does the design of the zoom lens impact image quality? - The design of the zoom lens, with a combination of fixed and movable lens units, allows for precise adjustments that can enhance image sharpness and clarity. 2. What are the potential drawbacks of using a zoom lens with multiple lens units? - One potential drawback could be increased complexity in the lens system, which may require more maintenance and calibration 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 negative refractive power, and a plurality of subsequent lens units. the zoom lens further includes an aperture stop. for zooming, the first lens unit is fixed, and the plurality of subsequent lens units move to change a distance between adjacent lens units. predetermined inequalities are satisfied.
