Note 1: The test condition for resolution is the center wavelength of 435.83 nm;

Note 2: CCD single-time spectral range, inverted line dispersion for the center wavelength of 435.83nm under the typical value, with the center wavelength increases, the spectral range becomes narrower;

Note 3: As the center wavelength increases, the value of the inverted line dispersion decreases, and as the center wavelength decreases, the value of the inverted line dispersion increases.
