SPEX 270M User Manual

270M Rapid Scanning Imaging Spectrograph
If acquisition of wavelengths beyond the width of the array are required, a tradeoff may
be made by using a lower groove density grating that will not disperse the
wavelengths so widely. Of course, with closer spacing, resolution would be lower. An
alternative, if experimental conditions permit, would be to keep the higher resolution
grating, but acquire more than one region, using the rapid slewing capability of the
270M to quickly reposition the grating. Depending on the software you are using,
overlapping regions may be "glued" to form continuous spectra.

EXPERIMENT
Multiple spectra from light imaged at various heights in the entrance slit can be
simultaneously detected with a two dimensional array such as a CCD. The capabilities
of a simple spectrograph are multiplied. This is made possible by the imaging optics,
which permit close vertical spacing of signals without crosstalk, unlike conventional
