Abstract

The optical scheme of grazing incidence monochromator with concave grating with variable space is offered. The monochromator has a simplified kinematic scheme of spectrum scanning mechanism. Scanning is obtained by turning the exit slit and grating, fixed with each other relatively to the axis that goes through the vertex of the concave grating while enter slit is fixed. Kinematic scheme provides change of grazing incidence angle and constant grazing angle of diffraction. Moreover, increase of grazing incidence angle affects an increase of the wave length. In this case shorter wave length radiation diffracts on the grating with more losses. This results in decrease of the highest spectrum orders, being not preferable. The well-known schemes on the Rowland circle have an entrance slit with significant linear motion, which makes the construction more complicated. Those conditions for changing the incidence and diffraction angles are not accepted in monochromators of constant angle of deviation.
