Corner wedges can be used individually to deflect laser beams to a certain angle, or combine two wedge prisms for beam deflection applications.
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.
