Spectra of Argon Gas Discharge

Note : There may be a small delay as each Applet loads its element emission line file and computes the spectra...

lineWidth too narrow, some lines disapear by undersampling.
wavelength=4000-7000, lineWidth=1, contrast=80, continuum=0.25

lineWidth near optimum, however some loss of brightness
wavelength=4000-7000, lineWidth=2, contrast=80, continuum=0.25

lineWidth optimum
wavelength=4000-7000, lineWidth=2.5, contrast=80, continuum=0.25

lineWidth large, some blurring but brighter than lineWidth=2
wavelength=4000-7000, lineWidth=3, contrast=80, continuum=0.25

lineWidth too large, blurring
wavelength=4000-7000, lineWidth=4, contrast=80, continuum=0.25
