Roof prisms, also known as Amici prisms, are optical prisms that deflect the line of sight by 90° while erecting the image — reverting and inverting it to maintain the correct visual orientation.
They are widely used in spotting scopes, binoculars, telescopes, and other optical instruments.

Amici prisms, also called "roof prisms" or "right angle roof prisms," revert and invert the image as well as bend the line of sight through a 90° angle. Ideal for use in spotting scopes, and any optical instrument where it is desirable to take an inverted image from an objective, turn it right side up, and bend it through a 90° angle in order to maintain the correct visual orientation.
Roof prisms are suitable for applications that demand both right-angle deflection and image erection (a combination of left-to-right reversal and top-to-bottom inversion, equivalent to a 180° rotation about the optical axis).

Scope of application:
1.Image erection: erects and reverts the image in binoculars, spotting scopes, and telescopes, maintaining correct visual orientation.
2.Right-angle deflection: bends the line of sight by 90° in periscopes and other optical systems.
3.Compact optical design: roof surfaces enable a folded optical path, allowing compact, high-performance instrument designs.
