One major drawback to a greatly enhanced depth of field in traditional scanning electron microscopy is the perceived loss of the apparent three dimensionality of an object.  As a result, the images can often appear flat and critical topographical features can be obscured. Stereo scanning electron microscopy can help resolve these issues by revealing previously undetectable three dimensional architectural complexities. To create this effect, two SEM images are acquired from different angles and the images are digitally combined to create an incredibly realistic composite.
