Half Penta Prism, Semipentaprisms, Used In Telescopes

Overview:

Half-Penta prisms also known as Bauernfeind prisms or Semi-pentaprisms are used to deviate the line of sight by 45° without inverting or reverting the image. It is widely used in telescopes and also has applications in projection and imaging system, in microscope tubes, and in geodesy.

 

The Half-penta prism has the geometrical structure of a penta prism cut in half. The beam is reflected twice in the prism, first with total internal reflection and a second time on a coated reflecting surface. The prism requires aluminized and over-coated with Inconel and black paint for the non-TIR surface to be usable in practice.

 

Combining a Half-Penta Prism with a correspond size Schmidt roof prism creates a Pechan prism pair. The Pechan prism pair will invert or revert the image while not deviating the line of sight.
