Description

Binoculars and Periscopes invert an image to make an object appear closer. There are two types of prisms that can be used for binoculars: Porro and Roof Prisms. Porro prisms are used in a pair to create an optical path. The image would pass through the first prism and which then inverts the image, the second prism then flips the image, so it is making the distant object appear closer. Roof prisms work in a similar fashion however are one prism and this design performs in the same way. Used particularly for smaller compact spaces as there are aligned in one piece to its objective lenses.
