Objective Lens Unit Layout for Stable Microscope Stage Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of spacers in microscope apparatuses to adjust the level position of the stage leads to increased shaking of the objective lens, affecting the accuracy of specimen observation due to displacement from the desired position.
Innovation Solution
A microscope apparatus design that includes a spacer system with electrical connections through lead wires and connectors to maintain stability and alignment of the nosepiece unit, stage, and illumination systems, minimizing lateral displacement of the objective lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spacer is disposed between the base and the pillar to adjust the level position of the stage, then the stage position can be adjusted, but the distance between the base and the nosepiece increases causing increased shaking in the XY direction
Solution Approach 1:
A rigid support structure (pillar) is introduced as an intermediary element between the base and the nosepiece support. This pillar provides a stable mechanical connection that maintains nosepiece stability even when spacers are used for stage position adjustment, thereby mediating between the conflicting requirements of position adjustability and stability.
2Ease of operation
If a spacer is disposed between the base and the pillar, then the stage level position can be adjusted, but the objective lens may be displaced from the desired position affecting observation accuracy
Solution Approach 1:
The pillar acts as a rigid intermediary structure that decouples the stage position adjustment (via spacers) from the nosepiece positioning. This ensures that when spacers are added or removed to adjust stage level, the objective lens position remains stable and accurate, preventing displacement that would affect observation precision.
Solution Approach 2:
The microscope apparatus is segmented into functionally independent modules: the base with driver, the pillar as a rigid support, the nosepiece support with spacers for stage adjustment, and the objective lens. This segmentation allows stage level adjustment via spacers without affecting the objective lens positioning, as each module can be adjusted independently.

AI summary
[Problem] An object is to observe a specimen accurately. [Means to Solve Problem] A microscope apparatus includes a base, a support disposed upright on the base, and an objective lens unit supported by the support and including an objective lens holder that holds an objective lens. The objective lens unit includes a drive source that moves the objective lens holder up and down and a driver that transmits a drive force of the drive source to the objective lens holder.
