Engineering Contradiction Analysis
1Productivity
If multiple sets of spectroscopic units are provided to simultaneously detect lights in multiple wavelength ranges, then detection efficiency is improved, but device size increases and detection accuracy decreases
Solution Approach 1:
Multiple spectroscopic units share a common reflection part, merging previously separate optical paths into a unified structure. This allows multiple wavelength ranges to be detected simultaneously while reducing the overall device size by eliminating redundant components.
Solution Approach 2:
The common reflection part serves multiple spectroscopic units simultaneously, enabling a single component to perform multiple functions. This multi-functional design allows the spectrometer to detect multiple wavelength ranges without proportionally increasing device size.
2Productivity
If multiple sets of spectroscopic units are provided to simultaneously detect lights in multiple wavelength ranges, then detection efficiency is improved, but detection accuracy decreases
Solution Approach 1:
The spectrometer is divided into multiple independent spectroscopic units, each with its own dispersive part and light detection part. This segmentation allows each unit to maintain optimized optical paths for its specific wavelength range, preserving detection accuracy while enabling simultaneous multi-wavelength detection.
Solution Approach 2:
Each spectroscopic unit is designed with specialized components optimized for its specific wavelength range. The dispersive parts and light detection parts are tailored to local requirements, ensuring high detection accuracy for each wavelength range while maintaining overall system efficiency.
3Measurement precision
If a single spectrometer is used to detect one wavelength range, then detection accuracy is maintained, but detection efficiency decreases when multiple wavelength ranges need to be detected
Solution Approach 1:
The spectrometer employs multiple spectroscopic units that can independently operate on different wavelength ranges simultaneously. This dynamic configuration allows the system to adapt to multi-wavelength detection requirements without compromising the detection accuracy of individual units.

AI summary
A spectrometer includes a first spectroscopic unit and a second spectroscopic unit. A light passing part, a reflection part, a common reflection part, a dispersive part, and a light detection part included in the first spectroscopic unit are arranged along a first reference line when viewed in a Z-axis direction. A light passing part, a reflection part, the common reflection part, a dispersive part, and a light detection part included in the second spectroscopic unit are arranged along a second reference line when viewed in the Z-axis direction. The first reference line and the second reference line intersect with one another.
