摘要 PCT No. PCT/EP92/01270 Sec. 371 Date May 16, 1994 Sec. 102(e) Date May 16, 1994 PCT Filed Jun. 5, 1992 PCT Pub. No. WO92/21948 PCT Pub. Date Dec. 10, 1992.An Echelle polychromator 50 has disposed upstream thereof a pre-monochromator 14 comprising a prism 20. The linear dispersion of the pre-monochromator 14 is variable by varying the angular dispersion of the prism 20. A particular spectral position and the close vicinity thereof are analyzed by an Echelle grating 54 with high resolution. Care must be taken that, on the one hand, the detector array 66 of the Echelle polychromator 50 is fully exploited in response to the central wavelength respectively observed and that, on the other hand, interfering orders are kept away from the Echelle polychromator 50. The linear dispersion of the pre-monochromator is variable for this purpose.
