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
