PROJECTION SYSTEM AND PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18599608 titled 'PROJECTION SYSTEM AND PROJECTOR
The patent application describes a projection system with multiple lens groups arranged in a specific sequence to control magnification.
- The system includes a first lens group with negative power, followed by a second, third, fourth, fifth, sixth, and seventh lens group with positive power.
- The second to sixth lens groups can be moved to adjust the magnification of the system, while the first and seventh lens groups remain fixed.
Potential Applications: - This technology can be used in projectors, cameras, microscopes, and other optical devices that require adjustable magnification. - It may also find applications in medical imaging equipment, scientific instruments, and industrial inspection systems.
Problems Solved: - Provides a compact and efficient way to control magnification in optical systems. - Offers flexibility in adjusting the magnification without the need for complex mechanisms.
Benefits: - Improved image quality and clarity due to precise magnification control. - Simplified design and operation of optical devices. - Enhanced versatility in various applications requiring adjustable magnification.
Commercial Applications: - "Adjustable Magnification Projection System: Enhancing Image Quality and Versatility in Optical Devices"
Prior Art: - Researchers can explore existing patents related to adjustable magnification systems in optical devices to understand the evolution of this technology.
Frequently Updated Research: - Stay updated on advancements in lens technology, optical system design, and magnification control mechanisms to enhance the performance of projection systems.
Questions about Adjustable Magnification Projection Systems: 1. How does the sequential arrangement of lens groups affect the overall performance of the projection system? 2. What are the key considerations when designing an adjustable magnification system for optical devices?
Original Abstract Submitted
A projection system includes a first lens group having negative power, a second lens group having positive power, a third lens group having positive power, a fourth lens group having negative power, a fifth lens group having positive power, a sixth lens group having positive power, and a seventh lens group having positive power that are sequentially arranged from the enlargement side toward the reduction side. The second lens group, the third lens group, the fourth lens group, the fifth lens group, and the sixth lens group are moved with the first lens group and the seventh lens group fixed to change the magnification of the projection system.
