ABSTRACT:
The invention relates to a grating monochromator for providing monochromatic radiation the wavelength of which is linearly proportional to a translation or rotation, said monochromator comprising an optical device including a reflection grating (1), an entrance slit (4) transmitting a beam onto the optical device, an exit slit (5) transmitting the beam reflected by the optical device, and a mechanism for moving the optical device and at least one of the slits (4,5) with respect to each other. Within said monochromator the moving mechanism is constructed so that in the course of the moving both the entrance slit (4) and the exit slit (5) are always positioned along a Rowland-circle (R) related to the optical device including the grating (1), and there is a transducer (42) producing an output signal corresponding to the current wavelength value, said transducer (42) being connected to a member (33) translating or rotating proportionally to a distance between a point (A) of the Rowland-circle (R) lying diametrically opposite to the optical device and said at least one slits (4,5). The moving mechanism expediently comprises means (41,33) for altering the distance between said point (A) of the Rowland-circle (R) lying diametrically opposite to the optical device and said at least one slit (4,5), and said member (33) translating or rotating proportionally to said distance is a part of said means.
