Abbe–Koenig prism
text:
An Abbe–Koenig prism is a type of reflecting prism, used to invert an image. They are commonly used in binoculars and some telescopes for this purpose. The prism is named after Ernst Abbe and Albert Koenig. The prism is made from two glass prisms, which are optically cemented together to form a symmetric, shallow Vee-shaped assembly. Light enters one face at normal incidence, is internally reflected from a 30° sloped face, and then is reflected from a "roof" section at the bottom of the prism. T
