Wedge Prisms

Optics >>> Prisms >> Wedge Prisms

Wedge prism is an optical element with plane-inclined surfaces, usually the faces are inclined toward one another at a very small angles.  It diverts light toward its thicker portion.  Wedge prisms can be used as isolating components.  Wedges may also be used to produce a small deviation which doesn't allow return to source.
