Roof Prism
Roof prism is combined with a right angle prism and a totally internally reflecting roof. It can revert and invert the image as well as bend the line of sight through a 90°angle. Ideal for use in 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.
