Paper Abstract

General approaches to the solution are shown on the example of one of the alternative variants of UV long-slit spectrometer. It is suggested using concave aberration-corrected holographic diffraction grating in FUV spectral range (102 – 175 nm). In NUV spectral range (175 – 310 nm), where mirror coating reflecting factor is higher, it is suggested using a beam of zero order of this grating with subsequent spectral decomposition performed with additional grating. It is known that diffractive grating efficiency depends on the form of grooves profile, in the first approximation step profile echelett grating fits quite well for this task.
