penta prism is a five-sided reflecting prism  used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism. The beam reflects inside the prism twice, allowing the transmission of an image through a right angle without inverting it (that is, without changing the image's handedness ) as an ordinary right-angle prism or mirror would.
