IMAGING LENS AND IMAGING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240280790 titled 'IMAGING LENS AND IMAGING APPARATUS
The imaging lens described in the patent application consists of three lens groups: a first lens group with negative refractive power, a second lens group with positive refractive power, and a third lens group with negative refractive power. During focusing, the first and third lens groups remain stationary with respect to the image plane, while the second lens group moves along the optical axis. The first lens group includes a first-a negative lens and a first-b negative lens, while the second lens group includes an aperture stop that moves integrally with the group during focusing.
- The imaging lens is composed of three lens groups with specific refractive powers and movements during focusing.
- The first and third lens groups do not move during focusing, while the second lens group moves along the optical axis.
- The first lens group includes two negative lenses, and the second lens group includes an aperture stop that moves with the group during focusing.
Potential Applications: - Photography lenses - Microscope lenses - Telescope lenses
Problems Solved: - Improved focusing capabilities - Enhanced image quality
Benefits: - Sharper images - Better control over focus - Versatile applications in various optical devices
Commercial Applications: Title: Advanced Imaging Lens Technology for Enhanced Optical Devices This technology can be used in the development of high-quality camera lenses, microscope lenses, and telescope lenses, catering to professionals in photography, microscopy, and astronomy industries.
Questions about the technology: 1. How does the movement of the second lens group impact the overall performance of the imaging lens? 2. What are the specific advantages of having a first lens group with negative refractive power in this configuration?
Original Abstract Submitted
the imaging lens consists of, in order from an object side, a first lens group having a negative refractive power, a second lens group having a positive refractive power, and a third lens group having a negative refractive power, and is configured such that, during focusing, the first lens group and the third lens group remain stationary with respect to an image plane, the second lens group moves in the direction of an optical axis, the first lens group includes a first-a negative lens and a first-b negative lens successively in order from a position closest to the object side, and that the second lens group includes an aperture stop that moves integrally with the second lens group during focusing.
