Test advantages
1. Comparison test, transmittance test, parameter comparison (rolling and locking modes)
2. Regular testing and regular saving (light attenuation test verification can be performed)
3. The wavelength is adjustable for easy query (a single band is more convenient for viewing and analysis)
4. Test result correction (test result coefficient correction for different scenarios and environmental changes)

Parameters:
1. Multiple optical inputs
2. Wavelength range: 350-800nm
3. Spectral resolution: ±0.2nm, wavelength resolution:
