RELAY SYSTEM AND PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240288662 titled 'RELAY SYSTEM AND PROJECTOR
The patent application describes a relay system consisting of three lens groups with different powers and arrangements.
- The first lens group is made up of positive power lenses, the second lens group includes a diaphragm and negative lenses, and the third lens group consists of positive power lenses.
- The number of lenses in the first and third groups are equal, and their power arrangements are symmetrical.
- The relay system has telecentric portions on both the enlargement and reduction sides.
Potential Applications: This technology could be used in optical systems, imaging devices, and cameras to improve image quality and focus.
Problems Solved: The relay system addresses issues related to image distortion, aberrations, and focus accuracy in optical systems.
Benefits: Enhanced image quality, improved focus accuracy, reduced aberrations, and better overall performance in optical devices.
Commercial Applications: This technology could be valuable in the development of high-quality cameras, medical imaging equipment, and industrial inspection systems.
Prior Art: Researchers can explore existing patents and publications related to relay systems, lens groups, and optical devices to understand the background of this innovation.
Frequently Updated Research: Stay informed about advancements in lens technology, optical system design, and imaging techniques to enhance the performance of relay systems.
Questions about the Technology: 1. How does the symmetrical arrangement of lens powers in the first and third groups contribute to the performance of the relay system? 2. What are the specific advantages of having telecentric portions on both the enlargement and reduction sides of the relay system?
Original Abstract Submitted
a relay system includes a first lens group formed of a plurality of lenses and having positive power, a second lens group including a diaphragm and at least one negative lens and having negative power, and a third lens group formed of a plurality of lenses and having positive power. the number of lenses of the first lens group and the number of lenses of the third lens group are equal to each other. the arrangement of the lens power of the plurality of lenses of the first lens group, which are arranged from the enlargement side toward the reduction side, is the same as the arrangement of the lens power of the plurality of lenses of the third lens group, which are arranged from the reduction side toward the enlargement side. the enlargement-side and reduction-side portions of the relay system are telecentric portions.
