CEMENTED LENS, OPTICAL SYSTEM INCLUDING THE SAME, OPTICAL APPARATUS, AND METHOD FOR MANUFACTURING CEMENTED LENS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18391446 titled 'CEMENTED LENS, OPTICAL SYSTEM INCLUDING THE SAME, OPTICAL APPARATUS, AND METHOD FOR MANUFACTURING CEMENTED LENS
Simplified Explanation
The patent application describes a cemented lens with multiple optical elements, a light shielding layer, and a porous layer.
- The lens includes a first, second, and third optical element.
- The third optical element is sandwiched between the first and second optical elements and contains resin.
- A light shielding layer covers a surface of the third optical element that is not in contact with the first or second optical elements.
- A porous layer covers at least a part of the light shielding layer.
Potential Applications
This technology could be used in:
- Camera lenses
- Microscopes
- Telescopes
Problems Solved
- Reduced light leakage between optical elements
- Improved image quality
- Enhanced durability of the lens
Benefits
- Improved optical performance
- Increased longevity of the lens
- Enhanced image quality
Potential Commercial Applications
Optical equipment manufacturers could use this technology in:
- Digital cameras
- Medical imaging devices
- Surveillance systems
Possible Prior Art
One possible prior art could be the use of anti-reflective coatings on lenses to reduce light reflection and improve image quality.
Unanswered Questions
How does the porous layer affect the overall performance of the lens?
The article does not provide details on how the porous layer impacts the functionality of the lens.
What materials are used in the construction of the light shielding layer?
The patent application does not specify the materials used in the light shielding layer.
