Предлагаемый монохроматор имеет спектральную область, расширенную не за счет смены дифракционных решеток, а за счет последовательного отражения светового пучка от двух граней профилированного штриха дифракционной решетки, находящихся под разными углами относительно параллельного пучка света. В соответствии с этим решетка имеет два максимума концентрации энергии в отличающихся спектральных областях, а суммарная кривая эффективности решетки охватывает больший спектральный диапазон, чем в случае однократной дифракции от одной грани штриха решетки.The proposed monochromator has a spectral region that is extended not by changing the diffraction gratings, but by sequentially reflecting the light beam from two faces of the graded line of the diffraction grating, which are at different angles relative to the parallel light beam. In accordance with this, the lattice has two maxima of energy concentration in different spectral regions, and the total curve of the lattice efficiency covers a larger spectral range than in the case of single diffraction from one face of the lattice line.
