• Right angle deflection
  • Correct image
  • Beam deviation 90

Pentaprisms are five-sided prisms that deflect the beam by 90° and produce a side-to-side image. Minor movements of the prism do not affect the right angle at which the rays are reflected. This makes a pentaprism the ideal optical component for defining a right angle in an optical system. These prisms are manufactured from various optical glasses - for applications in the visible spectrum - true to scale.
