The Slit group allows you to select the optical bandwidth of the
detector; the narrower the slit, the smaller the optical bandwidth
of the instrument, but the lower its sensitivity. The smaller the
optical bandwidth the higher the spectral resolution.
To set the slit width, display the drop-down list and select an
appropriate slit width from the list.
