AR Coated Conical Fused Quartz Prism

  • Pyramid prism is a kind of internal total reflection prism according to the critical angle principle
  • It is not influenced by incident angle and can reflect the incident light by 180 °
  • Any incident light entering clear aperture will be reflected back effectively according to the original direction
  • It uses three 90 ° to reflect the incident beam
  • The precision of pyramid prism is indicated by the angle error (parallelism) between incident beam and emergent beam, which is determined by the vertical precision among three right-angle planes
