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.
