</ref> It combines the full [[visible spectrum]] with an adjacent portion of the [[infrared]] [[spectrum]] up to the [[water absorption]] band between 1400 and 1500&nbsp;nm.
Some definitions also include the short-wavelength infrared band from 1400&nbsp;nm up to the water absorption band at 2500&nbsp;nm.<ref name=Waiser2007>{{cite journal
