Wedge prism is an optical element with plane-inclined surfaces;
usually the faces are inclined toward one another at very small
angles. It diverts light toward its thicker portion. By selecting the
appropriate wedge it is simple to create a precise beam deviation
without affecting other beam parameters. If two wedges are used
together with the sloping surfaces in close proximity it is possible
to produce a continuous variation of beam deviation by counter -
rotating the wedges.
