Amici Roof Prisms
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. With linearly polarized incident light, the light exiting an uncoated Amici prism is a mix of two elliptical polarizations which causes a reduction in contrast and resolution in some applications. The silver coated Amici roof prisms eliminate these issues.
