Inclined Optical Objective Mounting for Precision Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional objectives are limited in their ability to achieve small angles of inclination between the optical axis and the object being imaged, which is necessary for precise imaging and illumination tasks, especially in industrial and scientific applications.
Innovation Solution
A method for producing an objective with an outer mounting that has an inclined outer surface, involving machining of the lens and inner mounting surfaces to form planes, allowing for the insertion and precise fitting of lenses within the inner mounting, and subsequently into the outer mounting, enabling small angles of inclination.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional objectives are used with standard mounting structures, then the objective structure is simple and easy to manufacture, but the angle of inclination between the optical axis and the object surface cannot be made small enough for precise imaging tasks
Solution Approach 1:
The mounting structure is divided into an outer mounting and an inner mounting that can be independently manufactured and then assembled. The inner mounting holds the objective lens and can be inclined relative to the outer mounting, allowing the imaging precision to be optimized independently from the overall structure.
Solution Approach 2:
The patent introduces an angular dimension by inclining the inner mounting relative to the outer mounting. This allows the optical axis to be positioned at a small angle to the object surface while maintaining the structural integrity and manufacturability of the separate mounting components.
2Manufacturing precision
If the outer mounting has an inclined outer surface to achieve small angles of inclination, then the imaging precision at small angles is improved, but the manufacturing process becomes more complex
Solution Approach 1:
By segmenting the mounting into outer and inner parts, the complex inclined surface geometry is confined to the inner mounting only. The outer mounting maintains a simpler structure that is easier to manufacture, while the inner mounting with the inclined surface can be precisely manufactured and then assembled into the outer mounting.
3Manufacturing precision
If the outer circumference of lenses and inner mounting surfaces are machined to form planes, then the optical imaging precision is improved, but the manufacturing time and cost increase
Solution Approach 1:
The machining operations are segmented and performed on separate components (lens outer circumference and inner mounting surface) that can be manufactured in parallel. This allows the precision machining to be done on smaller, more manageable parts rather than on a complete assembled objective, improving manufacturing efficiency while maintaining high precision.
