ZOOM LENS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18402795 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS
The abstract describes a zoom lens with a unique configuration that includes a first lens unit with negative refractive power, a rear group with multiple lens units and an aperture stop, and an image stabilizing unit within the rear group that moves during image stabilization.
- The zoom lens includes a first lens unit with negative refractive power.
- The rear group consists of multiple lens units and an aperture stop.
- An image stabilizing unit within the rear group moves during image stabilization.
- A focus unit is positioned on the object side of the image stabilizing unit.
- The distance between adjacent lens units changes during zooming.
Potential Applications: - Camera lenses - Surveillance systems - Medical imaging devices
Problems Solved: - Image stabilization during zooming - Maintaining image quality in varying focal lengths
Benefits: - Improved image stabilization - Enhanced image quality - Versatile zoom capabilities
Commercial Applications: Title: Advanced Image Stabilized Zoom Lens for High-Quality Photography This technology can be used in professional photography equipment, surveillance cameras, and medical imaging devices, enhancing image quality and stability in various applications.
Questions about the technology: 1. How does the image stabilizing unit within the rear group contribute to the overall performance of the zoom lens? 2. What sets this zoom lens apart from traditional zoom lenses in terms of image stabilization and focus capabilities?
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 rear group including two or more lens units, and an aperture stop. The rear group includes an image stabilizing unit having negative refractive power and configured to move with a component in a direction orthogonal to an optical axis during image stabilization, and a focus unit disposed on the object side of the image stabilizing unit. A distance between adjacent lens units changes during zooming. A predetermined inequality is satisfied.
