Porro Prism Binoculars

This is the first design used in binoculars. It’s named after its inventor, an Italian by the name Ignazio Porro. It is made up of two Prisms that are at a right angle adjacent to each other. 

In this setup, the eyepiece and the objective lens are not in the same line. This is why the prism is right-angled so that light bounces sideways from the first prism into the other. It is set up in this way to lengthen the light path and to enhance image quality.
