UV: from 670 Å to 1609 Å (SOHO/Sumer), resolution 0.04 Å
Visible: from 3000 Å to 10000 Å (Jungfraujoch), resolution 0.002 Å or 500 pixels/Å
Infra Red: from 10000 Å to 54000 Å (Kitt Peak), resolution 0.004 cm-1 (varies from 0.004 Å at 10000 Å to 0.1 Å at 50000 Å)
The normalization of the solar spectrum is as follows: The continuum is estimated locally (in wavelength) and the intensities are normalized so that the continuum is 100 % (value 10000 on the plot). Continuity is preserved between different parts of the spectrum (it means that there is no discontinuity in the continuum). So, in fact, intensity are in 'local' arbitrary units.
