Roof Prism
A roof prism is a reflective optical prism containing a section where two faces meet at a 90° angle. These two 90° faces resemble the roof of a building, giving this prism type its name. Reflection from the two 90° faces returns an image that is flipped laterally across the axis where the faces meet.
PHYO can provide different roof prism type like Amici roof prisms, Schmidi Pedan Prism, and Abbe-koenig prism.
They are widely used in the telescope, periscope systems
