When replacing the light source of a used spectral analyzer due to insufficient intensity, the key parameters to match include the following:

1. Wavelength range: Must align with the instrument's detection wavelength requirements to ensure effective coverage of the target analytes.
2. Output intensity: Should meet or exceed the original specification to guarantee sufficient signal strength for accurate detection results.
3. Stability: Ensure long-term output stability to avoid fluctuations affecting the consistency of detection data.
4. Optical compatibility: Match the connector type, fitting size, and optical interface of the original light source to fit the instrument's optical system perfectly.
5. Brand/model specificity: For branded instruments (such as Thermofisher, Agilent, etc.), select accessories compatible with the specific model to ensure optimal performance.
