Wedge Prisms

 Wedge prism is an optical element with surfaces inclined toward each other at a very small angle. It diverts light toward the thicker area. Wedge prisms can be used as isolating components as well as to produce a small deviation which doesn't allow return to source.

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.
