Penta Prisms
Description
Penta Prisms are used to define right angles in optical systems. Penta Prisms,which provide right handed images,feature
a ray deviation of 90°. Penta Prisms are five-sided prisms are unaffected by slight movements. Edmund Optics offers a
variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums.
