ZOOM LENS AND APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240176214 titled 'ZOOM LENS AND APPARATUS INCLUDING THE SAME
Simplified Explanation
The patent application describes a zoom lens with a specific configuration of lens units that allows for zooming, image stabilization, and focusing while satisfying predetermined inequalities.
- First lens unit: negative refractive power
- Second lens unit: positive refractive power, moves in zooming
- Rear lens group: includes focus lens unit that moves in focusing
- Subunits L and Lh in second lens unit move for image stabilization
- Distance between lens units changes in zooming
Potential Applications
The technology can be applied in:
- Camera lenses
- Microscopes
- Telescopes
Problems Solved
- Maintaining image quality during zooming
- Providing image stabilization
- Allowing for focusing without compromising image quality
Benefits
- Improved image quality
- Versatile functionality
- Enhanced user experience
Potential Commercial Applications
"Zoom Lens Technology for High-Quality Imaging"
Possible Prior Art
Prior art may include existing zoom lens designs with image stabilization features.
Unanswered Questions
How does this technology compare to existing image stabilization systems in terms of effectiveness and cost?
The article does not provide a direct comparison with other image stabilization systems, leaving room for further research and analysis.
What are the specific predetermined inequalities that the zoom lens must satisfy, and how do they impact the overall performance of the lens?
The article mentions predetermined inequalities that the zoom lens must satisfy but does not elaborate on their exact nature or implications, requiring additional investigation to fully understand their significance.
Original Abstract Submitted
a zoom lens includes a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a rear lens group including one or more lens units, which are disposed in this order from an object side to an image side, wherein a distance between adjacent lens units changes in zooming, wherein the first lens unit does not move and the second lens unit moves in zooming, wherein the second lens unit includes subunits land lhaving a positive refractive power, which are disposed in this order from the object side, wherein the subunit lmoves to include a component in a direction perpendicular to an optical axis in image stabilization, wherein the rear lens group includes a focus lens unit that moves in focusing, and wherein the zoom lens satisfies predetermined inequalities.
