A variety of factors must be controlled in order to obtain stereo micrograph pairs with the SEM which provide maximum effectiveness along with ease of viewing. These include the following:1. Where possible, micrographs should be sharp from edge to edge. This may require the use of an Autofocus attachment although somewhat the same effect can be obtained by maintaining the point of sharpest focus near opposite edges of the two micrographs forming the stereo pair.2. The difference in tilt angle between the two micrographs of the pair should be kept in the 4to 6° range to provide a normal perspective.3. Micrographs forming a stereo pair should be made at relatively low tilt angles to prevent large differences in the field of view of the two micrographs and to minimize the left to right magnification variations.

The procedure detailed allows the projection and viewing of stereoscopic slides without the use of a special stereo projector or a polarizing screen; a standard lantern slide projector is used, and the slides are viewed through red and green acetate filters.A stereo pair is taken on a scanning electron microscope with a tilt difference of 7° (Fig. 1). After the first member of the pair is taken, the sample is tilted. The image is refocused by means of the z-axis control and recentered by means of the x- and y-axis controls. These two manipulations ensure that both micrographs in the stereo pair are at the same magnification and that they will be superimposed properly on the color slide.A Polaroid MP-3 Industrial Viewer, a Graflex 120 roll film back, and a framing table (or equivalent equipment) can be used to make stereo slides from stereo pairs.

AbstractStereo pair imaging in a scanning electron microscope was used to document the details ofthe topography of fracture surfaces at various degrees of magnification. The fracture surfaces had been produced by fracture testing of chevron-notched beam specimens according to ISRM Method I. The surfaces examined included the fracture surfaces of dolomite and andesite rocks, cement pastes with and without silica fume, the fracture surfaces from specimen prepared by casting cement paste on previously fractured rock specimen faces, and the fracture surfaces of mortars prepared using the same rock types and cement pastes. The principal topographic features of the various fracture surfaces are described.
