(a) The spectrum of the Hg(Ne) lamp versus the pixel number of the sCMOS; (b) the conversion relation between the pixel number and wavelength obtained by linear fitting the data points 435.84 nm, 546.07 nm, 576.96 nm, and 579.07 nm of the Hg(Ne) lamp and 650nm of a diode laser. (c),(d) The spectra of the Hg(Ne) emission lines at (c) 546.07 nm and (d) 576.96 nm and 579.07 nm. Red lines are the Gaussian fitting curves.
