Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Raman infrared compound microscope devices become large in size due to the incorporation of separate visible light sources for Raman and infrared analyses, making it difficult to observe samples with visible light while performing both analyses.
Innovation Solution
A Raman infrared compound microscope device is designed with a first light source for laser light, a second light source for infrared light, and a third light source for visible light, along with a first optical system that orients visible light in different directions between Raman and infrared analyses, allowing for compact device design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate visible light sources are incorporated for both Raman and infrared analyses, then sample observation capability is improved, but device size increases
Solution Approach 1:
The patent applies universality by making the visible light source serve multiple functions: it is used both for illuminating the sample during Raman analysis and for illuminating the sample during infrared analysis. This single visible light source replaces what would traditionally require two separate visible light sources, thereby reducing device size while maintaining full sample observation capability across both analysis modes.
Solution Approach 2:
The patent merges the function of visible light illumination for both Raman and infrared analyses into a single visible light source and optical path. By combining these functions and sharing the visible light source between the two analysis systems, the device achieves compact size without sacrificing the ability to observe samples during either type of analysis.
2Volume of moving object
If a single visible light source is used for both analyses, then device size is reduced, but optical path complexity increases
Solution Approach 1:
The patent applies dynamics by using a movable reflecting mirror that can change its reflection angle to direct visible light differently depending on the analysis mode. When performing Raman analysis, the mirror directs light to the Raman optical system; when performing infrared analysis, the mirror redirects light to the infrared optical system. This dynamic switching mechanism allows a single visible light source to serve both functions without requiring complex permanent dual-path optics.
Solution Approach 2:
The patent introduces a reflecting mirror as an intermediary component that mediates between the single visible light source and the two different optical systems (Raman and infrared). This intermediary element enables the visible light to be dynamically routed to the appropriate system, simplifying the overall optical design compared to creating two separate fixed optical paths from the light source.

AI summary
A Raman infrared compound microscope device includes: a first light source that generates laser light; a second light source that generates infrared light; a third light source that generates visible light; and a first optical system. The first optical system orients the visible light having reached the first optical system in different directions between when performing a Raman analysis using Raman light generated from a sample by irradiation of the laser light and when performing a first infrared analysis using the infrared light having passed through the sample.
