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.
Wedge prisms are available in alternative materials, such as UV grade fused silica, and in different shapes and sizes, or with various anti-reflection coatings.
