A monochromator optical design is described, which comprises a grazing-incidence reflection grating and two grazing-incidence mirrors, one on each side of the grating. The grating operates in conical diffraction mode and has an exponential phase function, so that the wavelength can be scanned by translating the grating surface in the phase-gradient direction. The wavelength can be continuously tuned over a wide spectral range while maintaining zero-aberration performance over the full range, and perfect blazing is also achieved over the full illumination aperture at all wavelengths.
