ZOOM LENS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240241355 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS
The abstract of the patent application describes a zoom lens with a specific configuration of lens units and elements, as well as the satisfaction of predetermined inequalities.
- The zoom lens consists of a first lens unit with negative refractive power, a second lens unit with positive refractive power, and an aperture stop.
- The distance between adjacent lens units changes during zooming, allowing for variable focal lengths.
- The first lens unit is composed of at least three or four lens elements, contributing to the overall optical performance of the lens.
- The design of the lens satisfies predetermined inequalities to ensure optimal image quality and performance.
Potential Applications: - Photography and videography equipment - Surveillance systems - Medical imaging devices - Scientific research instruments
Problems Solved: - Variable focal lengths for different zoom levels - Maintaining image quality throughout the zoom range - Achieving precise focus and clarity in images
Benefits: - Versatile zoom capabilities - High-quality images with minimal distortion - Enhanced optical performance in various applications
Commercial Applications: Title: Advanced Zoom Lens Technology for Enhanced Imaging This technology can be utilized in professional cameras, security systems, medical imaging devices, and scientific instruments, offering improved zoom capabilities and image quality for a wide range of commercial applications.
Questions about Zoom Lens Technology: 1. How does the configuration of lens units impact the performance of the zoom lens? The specific arrangement of lens units and elements in the zoom lens contributes to its overall optical performance, including factors such as focal length, image quality, and distortion control.
2. What are the key advantages of using a zoom lens with variable focal lengths? A zoom lens with variable focal lengths offers flexibility in capturing images at different distances without the need to change lenses, making it a versatile tool for various photography and imaging applications.
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, a second lens unit having positive refractive power, and an aperture stop. a distance between adjacent lens units changes during zooming. the first lens unit includes at least three or four lens elements. predetermined inequalities are satisfied.
