prism, that is used to invert (rotate by 180°) an image. The special feature of this prism is that, like a
Porro prism, it manages this with only four beam deflections, and has neither a roof edge, a mirrored surface or an air gap. In contrast to the Porro prism, however, it leads to a significantly reduced axis offset, which allows the construction of comparatively more compact
binoculars. The inversion system was pat...')
