The images obtained with a classical Czerny-Turner design and a crossed beam Czerny-Turner design are compared, imposing in both cases the Fastie and the Pribram and Penchina conditions. The results show that the astigmatic line may be made parallel to the spectral line only with the classical design, which makes it superior to the crossed beam design. Also, the importance of an adequate choice of the construction parameters is shown. The analytical calculations are checked by ray tracing.
