Core devices
1. Band response range 380-780nm
2. Enhanced coating grating: number of lines: 600 lines
3. Enhanced collimator, focusing lens
4. 16 bit high-speed AD sampling
5. High precision and stable computing circuit
6. High precision optical path, small stray light, elimination of high-order diffraction spectrum (cloud spectrum filtering system)

Advantages of testing
1. Comparative testing, transmittance testing, parameter comparison (rolling and locking modes)
2. Timing testing, timing saving (can be verified through light attenuation testing)
3. Wavelength adjustable for easy query (single band for easier viewing and analysis)
4. Compensation for test results (coefficient compensation for test results for different scenarios and environmental changes)
5. Online testing
