Microscope Slider Integrating Polarizer and Analyzer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual microscopes require multiple steps and risk operator error when switching between observation methods like PlasDIC and fluorescence contrasting, due to the need for manual removal and reconfiguration of polarizers, analyzers, and shearing elements, which limits efficiency and accuracy.
Innovation Solution
A slider with a stack of optical elements where the analyzer's polarizing direction is fixed relative to the polarizer, allowing for interchangeable stacks and additional sockets for other observation methods, enabling single-hand removal of components and flexible positioning for reduced operational complexity and error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual removal and reconfiguration of polarizers, analyzers, and shearing elements is performed when switching between observation methods, then the microscope can be used for multiple observation methods, but the number of steps increases and operator error risk increases
Solution Approach 1:
The patent combines the polarizer, analyzer, and shearing elements into a single integrated slider assembly that moves as one unit. This merging of previously separate components eliminates the need for manual reconfiguration of multiple individual elements when switching between PlasDIC and fluorescence observation methods, thereby reducing the number of steps and operator error risk while maintaining versatility
Solution Approach 2:
The slider is designed with multiple sockets that can accommodate different optical element configurations for various observation methods. By making the slider universal and capable of holding different combinations of optical elements, the system can switch between PlasDIC, fluorescence, and other observation methods using a single integrated component rather than requiring separate manual setup for each method
2Adaptability or versatility
If multiple separate components (polarizer, analyzer, shearing elements) are used for PlasDIC method, then the observation method can be implemented, but the operational complexity increases when switching to other methods
Solution Approach 1:
The patent merges the polarizer, analyzer, and shearing elements into a single integrated slider assembly. This consolidation reduces device complexity by treating multiple components as one unit that can be inserted or removed as a whole, thereby simplifying the operational process when switching between observation methods while maintaining the full functionality of the PlasDIC method
3Ease of operation
If fixed orientation of analyzer relative to polarizer is implemented in the slider, then switching between methods becomes easier, but flexibility in component configuration is reduced
Solution Approach 1:
The slider incorporates multiple sockets that can accommodate different optical element configurations, making the device universal. The fixed orientation within each socket ensures ease of operation, while the ability to choose from different socket configurations maintains adaptability for various observation methods including PlasDIC and fluorescence
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
Facilitates easier switching between contrasting methods by reducing the number of steps and components to be moved, allowing for flexible use with various objectives and methods, thereby enhancing operational efficiency and reducing the likelihood of errors.
Implementation Method 1
A polarizer for creating linearly polarized light is arranged in the beam path upstream of the first Nomarski prism
Implementation Method 2
The polarization directions of polarizer and analyzer are normal to each other. The drawback of this arrangement is that the objective as well as all optical elements in the illumination beam path must be isotropic with regard to polarization
Implementation Method 3
The second prism recombines the two partial beams, which can interfere with each other behind the analyzer
