The minimum starting wavelength of 190nm is closer to the short ultraviolet band than VL11639-190-540 (starting at 200nm), and can detect the spectra of special substances in the 190-200nm range (such as the short ultraviolet characteristic peaks of certain gases);
It takes into account deep ultraviolet and short-wave visible light, and can complete the combined measurement of "deep ultraviolet absorption + short-wave visible light reflection" in one go without replacing the instrument;
The CCD quantization background noise is ≤30 RMS (minimum integration time), which performs excellently in weak signal detection in the 190-540nm band, with stable data signal-to-noise ratio.
