OPTICAL SYSTEM, IMAGE PICKUP APPARATUS, AND LENS APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337904 titled 'OPTICAL SYSTEM, IMAGE PICKUP APPARATUS, AND LENS APPARATUS
The optical system described in the patent application consists of a series of lenses with specific refractive powers and surface characteristics. The first lens is negatively powered, followed by a positively powered second lens, a positively powered third lens, and a negatively powered fourth lens. The first lens has an aspheric surface on the object side, with a curvature that increases from the central portion to the peripheral portion.
- The optical system includes lenses with different refractive powers arranged in a specific order.
- The first lens has an aspheric surface with a unique curvature profile.
- The arrangement of lenses in the system is designed to achieve certain predetermined inequalities.
Potential Applications: - Camera lenses - Microscopes - Telescopes
Problems Solved: - Improving image quality - Reducing optical aberrations
Benefits: - Enhanced optical performance - Sharper images - Improved clarity
Commercial Applications: Title: Advanced Optical Systems for High-Resolution Imaging This technology can be used in various commercial applications such as high-end cameras, medical imaging equipment, and scientific instruments. The improved optical performance can attract professionals and enthusiasts looking for superior image quality.
Questions about the technology: 1. How does the unique curvature profile of the first lens surface contribute to the overall performance of the optical system? 2. What specific advantages does the arrangement of lenses with different refractive powers offer compared to traditional optical systems?
Original Abstract Submitted
an optical system includes, in order from an object side to an image side, a first lens having negative refractive power, a second lens having positive refractive power, a third lens having positive refractive power, and a fourth lens having negative refractive power. a first lens surface on the object side of the first lens is aspheric, and the first lens surface has an area in which a curvature that is convex toward the object side increases from a central portion to a peripheral portion. predetermined inequalities are satisfied.
