This invention relates to a spectrograph-monochromator of grazing incidence type which is particularly but not exclusively designed for examining soft x-ray and ultraviolet radiation. the spectrograph-monochromator according to the invention comprises an inlet slit, a reflecting diffraction grating and a detector comprising a photographic plate for spectrographic recording or, alternatively, an outlet slit for selecting a single monochromatic component, the improvement being that the inlet slit is disposed in a fixed position relative to a base plate, provided with an openable cover and said grating and said detector are disposed longitudinally displaceable on a curved guide, which represents a portion of a Rouland circle and is rotatable about an axis coinciding with that of said inlet slit.
A spectrograph-monochromator of grazing incidence type, particularly for soft X-ray and ultraviolet radiation, comprising a base plate and an openable upper cover which define a closed space having vacuum forming means associated thereto, a stationary inlet slit housed in said closed space, a curved guide formed as a portion of a Rowland circle and connected to said base plate through a pivot coaxial with said inlet slit, and a reflecting diffraction grating and a detector which are slidingly mounted on said curved guide and are independently displaceable along the same.
