Porro prisms are sections of right angle prisms. They are specifically intended for 180deg folding. These porro prisms are circular in cross section and have a lambda/10 polishing inner face. An incoming beam is reflected at the roof faces and returned in the opposite direction, the beam deviation is within 10 arcsec.
