ZOOM LENS AND IMAGING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240264416 titled 'ZOOM LENS AND IMAGING APPARATUS
The abstract of the patent application describes a zoom lens with a specific configuration of lens groups that change spacing during zooming and focusing while meeting certain conditions related to focal length and angle of view.
- The zoom lens consists of a first lens group with negative refractive power, a middle group, and a final group.
- The spacing between the first lens group and the middle group changes during zooming, as does the spacing between the middle group and the final group.
- During focusing, at least part of the middle group moves while the first and final groups remain stationary.
- The zoom lens must satisfy predetermined conditional expressions regarding back focal length, focal length, and maximum half angle of view.
Potential Applications: - Photography and videography equipment - Surveillance systems - Medical imaging devices
Problems Solved: - Maintaining image quality while zooming and focusing - Achieving precise control over focal length and angle of view
Benefits: - Enhanced image quality - Improved flexibility and versatility in capturing images - Consistent performance across different zoom and focus settings
Commercial Applications: Title: Advanced Zoom Lens Technology for High-Resolution Imaging This technology could be used in high-end cameras, professional video equipment, and other imaging devices where precision and image quality are paramount. The market implications include catering to professionals in various industries who require top-notch imaging capabilities.
Prior Art: Researchers and developers in the field of optics and imaging technology may find relevant prior art in patents related to zoom lenses, lens configurations, and optical systems.
Frequently Updated Research: Ongoing research in lens design, optical materials, and image processing techniques may impact the development and improvement of zoom lens technology.
Questions about Zoom Lens Technology: 1. How does the configuration of lens groups in this zoom lens differ from traditional zoom lenses? 2. What are the key factors that determine the performance and quality of images produced by this zoom lens?
Original Abstract Submitted
the zoom lens consists of, in order from an object side to an image side, a first lens group having a negative refractive power, a middle group, and a final group. during zooming, a spacing between the first lens group and the middle group changes, and a spacing between the middle group and the final group changes. during focusing, at least a part of the middle group moves, and the first lens group and the final group remain stationary with respect to an image plane. the zoom lens satisfies predetermined conditional expressions about aback focal length, a focal length, and a maximum half angle of view.
