Penta Prisms

Penta prisms deviate a line of sight or input beam by precisely 90°. Penta Prisms provide right handed images, feature a ray deviation of 90°. The deviation angle of 90 is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in plumb level, surveying, alignment, range finding and optical tooling. The reflecting surfaces of this prism must be coated with a metallic or dielectric coating. The standard penta prism reflecting surfaces are coated with aluminum or enhanced aluminum.


XF Photonics offers a variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums. Our penta prisms are available in 5 and 50.8 mm sizes or customization. The geometry of these prisms requires the reflecting surfaces to be coated. The reflecting surfaces of our penta prisms are coated with protected aluminum with a black paint overcoat. The entrance and exit faces are uncoated but can be antireflection coated. Please contact us if you require any penta prisms.
