PROJECTION SYSTEM AND PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240302636 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 seven lens groups, each with different optical powers, arranged from the enlargement side to the reduction side.
- The second to sixth lens groups can move to adjust the magnification, while the first and seventh lens groups remain fixed.
- This design allows for precise control over the magnification of the projection system.
Potential Applications: - This technology can be used in projectors, microscopes, telescopes, and other optical devices that require adjustable magnification. - It can also be applied in medical imaging equipment, scientific instruments, and photography lenses.
Problems Solved: - Provides a solution for adjusting magnification in optical systems without the need for external attachments or complex mechanisms. - Offers a more compact and efficient way to control magnification in projection systems.
Benefits: - Improved flexibility and precision in adjusting magnification levels. - Enhanced image quality and clarity in optical devices. - Simplified design and operation of projection systems.
Commercial Applications: Title: Advanced Projection System with Adjustable Magnification This technology can be utilized in the development of high-quality projectors for home entertainment, professional presentations, and educational purposes. It can also find applications in the manufacturing of optical instruments for various industries, including healthcare, research, and photography.
Prior Art: Readers interested in exploring prior art related to this technology can start by researching patents and publications in the field of optical systems, lens design, and projection technology.
Frequently Updated Research: Researchers and developers in the field of optics and imaging technology are constantly working on advancements in lens design, optical materials, and projection system efficiency.

Questions about Projection Systems: 1. How does the arrangement of lens groups in this projection system contribute to its overall performance? The specific sequence of lens groups in the system allows for precise control over magnification levels, ensuring high-quality images with minimal distortion.
2. What are the potential challenges in implementing adjustable magnification in optical devices, and how does this technology address them? Implementing adjustable magnification in optical devices can be challenging due to the complexity of lens movements and alignment. This technology simplifies the process by integrating movable lens groups within the system, offering a more efficient and compact solution.
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.
