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 20240118458 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 for improved optical performance.

  • The cemented 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 various optical devices such as cameras, microscopes, telescopes, and other imaging systems.

Problems Solved

1. Improved optical performance by reducing light leakage and reflections. 2. Enhanced durability and longevity of the lens due to the protective layers.

Benefits

1. Enhanced image quality and clarity. 2. Increased resistance to environmental factors such as dust and moisture. 3. Extended lifespan of the lens.

Potential Commercial Applications

"Advanced Cemented Lens Technology for Optical Devices"

Possible Prior Art

There may be prior art related to cemented lenses with light shielding layers and porous coatings for optical devices.

Unanswered Questions

How does this technology compare to existing lens designs in terms of weight and size?

The article does not provide information on the weight and size of the cemented lens compared to traditional lens designs. This could be important for applications where weight and size are critical factors.

What is the cost implication of incorporating these additional layers into the lens manufacturing process?

The article does not address the cost implications of adding the light shielding layer and porous layer to the lens. Understanding the cost-effectiveness of this technology is crucial for its commercial viability.


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.
