Fresnel prisms and beam dividers

A Fresnel prism replaces the sloping surface of a wedge by a series of facets moulded in acrylic, with a great saving of weight and cost. Fresnel prisms are also called as analogous to Fresnel lenses and are not to be confused with Fresnel rhombs or Fresnel biprisms.

In the Fresnel beam divider alternate facets are reversed, so dividing the light into two beams deviated in opposite directions.
