Pentaprism with magnification, which surface is curved?

[QUOTE="nikosb, post: 6633216, member: 239915"] I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the fours surfaces? Can the reflecting side be curved like a spherical concave mirror? What is the relation between the radius of curvature and the focal length? [/QUOTE]
