Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cemented lenses face challenges in effectively correcting chromatic aberrations due to the limitations of resin adhesive layers, particularly in achieving a high θg,F value for optimal optical performance.
Innovation Solution
A novel compound represented by Formula (1) is used to create a resin precursor, which when combined with specific curable compositions, results in a cured object with enhanced optical characteristics, including a high θg,F value, enabling effective chromatic aberration correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resin adhesive layer is used to join lens elements, then the lens elements can be joined together, but the chromatic aberration correction is insufficient
Solution Approach 1:
The patent changes the chemical composition parameters of the resin adhesive layer by introducing specific compounds with high θg,F values (such as compounds containing fluorine atoms or aromatic rings). This parameter change enables the resin to achieve both good adhesion and excellent chromatic aberration correction, resolving the contradiction between joining capability and optical performance.
Solution Approach 2:
The patent creates a composite resin adhesive layer by combining multiple components: base resin, compound of Formula (1) with high θg,F value, and optional additives. This composite structure allows the resin to simultaneously provide mechanical bonding strength and superior chromatic aberration correction, addressing both requirements of lens element joining and optical performance.
2Device complexity
If conventional resin adhesive layers are used, then the structure is simple, but the optical performance is limited
Solution Approach 1:
The patent modifies the chemical parameters of the resin by incorporating specific compounds (Formula (1)) with high θg,F values. This parameter change improves optical performance without significantly complicating the overall resin structure, as the compounds are integrated into the existing resin matrix rather than creating entirely new material systems.
3Reliability
If the resin adhesive layer has high θg,F value, then chromatic aberration correction is improved, but manufacturing complexity increases
Solution Approach 1:
The patent achieves high θg,F values by selecting specific chemical compounds (such as fluorinated compounds or aromatic compounds) that can be easily incorporated into the resin during standard manufacturing processes. This parameter change approach improves chromatic aberration correction without requiring complex manufacturing procedures, as the compounds are simply mixed into the resin formulation.
