Abstract: The grating of an asymmetric, double pass, grating monochromator has an axis of rotation which extends at an angle Psi relative to a normal to a plane H H''. That plane is normal to, and bisects, a line extending between the monochromator entrance and exit slits. The angle Psi is characterized in that spectral overlap is substantially elmininated.
