Penta prism
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. Ricun offers a variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums.
Penta prism are made of optical galss, sapphire ,fused silica, CaF2, MgF2, Baf2, silicon ,Germanium and Znse
