Adjustable Lens Mount Using Low-Stiffness Spacer Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable lens mounts for strip lenses require significant installation space and restrict the beam path, making it difficult to accommodate additional optical or mechanical components due to their design, which extends beyond the thickness of the strip lens and limits mechanical stability.
Innovation Solution
An adjustable lens mount design that uses a spacer strip with minimal flexural strength and high compressive strength, interconnected with a support strip and mounting plate, allowing for deformation of the strip lens while minimizing the installation space required, achieved through a combination of set screws and a three-point bearing system, enabling indirect attachment of the mounting plate for enhanced flexibility and reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support strip is designed wider than the joining area to provide assembly surface for set screws, then the mechanical stability and adjustability of the lens mount is improved, but the installation space required adjacent to the strip lens increases and the beam path is restricted
Solution Approach 1:
The patent repositions the assembly surface from the width dimension to the length dimension of the support strip. By providing a long narrow assembly surface extending along the longitudinal extent of the strip lens, the design allows set screws to be arranged in the longitudinal direction rather than requiring lateral width, thus maintaining mechanical stability while minimizing the installation space adjacent to the lens.
2Adaptability or versatility
If the support strip is made wider to accommodate multiple set screws for adjustment, then the deformability and adjustment capability of the strip lens is improved, but the installation space and material usage increase
Solution Approach 1:
The patent transitions the adjustment mechanism from a lateral width-based arrangement to a longitudinal length-based arrangement. The assembly surface extends along the longitudinal extent of the support strip, allowing multiple set screws to be positioned in the longitudinal direction, thereby providing comprehensive adjustment capability while minimizing the lateral installation space required.
3Device complexity
If the mounting plate is directly attached to the support strip, then the structural simplicity is improved, but the flexibility and adaptability of the lens mount design is reduced
Solution Approach 1:
The patent divides the mounting structure into separate functional components: a support strip for holding and adjusting the strip lens, and a mounting plate for securing the assembly to external structures. This segmentation allows independent optimization of each component and provides flexibility in mounting configurations while maintaining overall structural simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces the installation space needed adjacent to the strip lens, allowing for more components to be placed nearby and improving mechanical stability by minimizing the required forces for adjustment, while maintaining precise deformation capabilities in the sub-micrometer range.
Implementation Method 1
the spacer strip (7) has a flexural strength which is as low as possible... the support strip and, as a result, the strip lens can be deformed over its length in the action direction of the first and second set screws
Implementation Method 2
first set screws (4.1)... and second set screws (4.2)... which are arranged alternately in a row, such that the support strip and, as a result, the strip lens can be deformed over its length in the action direction of the first and second set screws

AI summary
A lens mount for a strip lens is provided, in which the strip lens can be deformed substantially perpendicular to its optical axis, in order to linearize the imaging of a beam scanning over the strip lens. The lens mount includes a slotted distance strip, a support strip and a base plate. The support strip is rigidly connected to the strip lens via the distance strip that has only a very low bending stiffness and can be deformed relative to the base plate by means of adjusting screws, whereby the strip lens can be deformed. By inserting a distance strip, the installation space that is required for the lens mount is essentially moved away from the optical axis in order to provide, for example, installation space for adjacent optical or mechanical components.
