==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.


==Original Abstract Submitted==

A cemented lens includes a first optical element, a second optical element, a third optical element sandwiched between the first optical element and the second optical element and containing resin, a light shielding layer covering a surface of the third optical element that is in contact with neither the first optical element nor the second optical element, and a porous layer covering at least a part of the light shielding layer.
