An Schmidt prism, named for its inventor, the German Bernhard Schmidt??? , is a type of reflecting prism used to deviate a beam of light by 45°, while flipping the image vertically. The beam is reflected three times in the prism, with all reflections being total internal reflection. A variation of the Schmidt prism is the Schmidt roof prism, which replaces the second reflective face with a roof section. Thus the Schmidt roof prisms flips the image both vertically and horizontally,.

The Schmidt roof prism is commonly used in microscope tubes to deviate the path to the eyepiece in order make the device more ergonomic while simultaneously erecting the image.
