1Measurement precision
If conventional spectral analysis instruments are used, then spectral analysis capability is achieved, but device complexity and size increase
Solution Approach 1:
The patent combines multiple spectral analysis components (light source, diffraction grating, photosensitive detector) into an integrated micro spectrometer module. This merging of previously separate components into a single compact unit directly reduces device complexity while maintaining spectral analysis capability, resolving the technical contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent implements a nested structure where the optical crystal, lens, and photosensitive assembly are arranged in a compact nested configuration within the micro spectrometer housing. This nesting approach allows multiple functional elements to be contained within a small volume, reducing overall device size and complexity while preserving full spectral analysis functionality.
