What is an Roof Prism or Amici Prism?
Roof prism is also called “right angle roof prism” or “Amici prism”.
An optical roof prism is a reflective prism consisting of two faces that intersect at an angle of 90°. Reflections from two 90° faces return images that cross laterally on the axis where the faces meet.
Features:
A characteristic feature of the distance of a amici roof prism is that the beam house is split in two, half of the beam hits first side and then the other side, while the other half of the beam is inverted.
Therefore, a roof prism can be used at a certain distance from the focal plane, otherwise the angle between the two surfaces must be very close to 90 degrees, otherwise the image quality will be affected.
Roof prisms are suitable for telescoping or any other application involving image segmentation or bending a beam of light 90° to maintain the desired theoretical direction.
Generally, the processing technology of right-angle roof prisms is mature and the diameter is easy to realize. The accuracy of prisms with a diameter of 1 to 2 inches can be controlled within 2 seconds.
Application:
Bote Optics’ roof prisms are widely used in telescopes, observation mirrors, prism diagonals in optical systems, and optical tools.
