Feature Description
Collect/Stop Preview Collects a chemical image of the selected preview region using the
current
acquisition settings . The preview region is the area inside
the preview box . The preview image is displayed in the left pane.
If you move or resize the preview box during acquisition, the

Preview image A scan that contains an average spectrum collected at each
sampling point in the
preview box . The number and locations of
the spectra that make up the preview image are defined by the
Image pixel size setting. The number of passes is defined by the
Number of scans setting. The preview image is useful for
optimizing the Image pixel size setting before acquiring chemical
image data in the final selected regions.
Preview status Before collecting the preview data, this area shows the size of the
preview region in pixels, the estimated time required to acquire
the preview data, and the amount of computer memory needed to
store it. These values update each time you change the boundaries
of the preview box or the

evaluate the impact on time and available memory.
During preview acquisition, this area shows the start time, percent
completion and time for each scan and the estimated time to
complete all requested scans of the preview region.
