The Klag prism performs an image rotation. A spectrometer consists of a dispersive and a nondispersive axis. Placing the prism in front of the entrance optics of a spectrometer,the axes are interchanged. Very important for two dimensional samples. For example if a sample has to be scanned, instead, one spectrum should be taken with and one without the prism.
