    摘要: A Rowland circle-type polychromator with the Rowland circle arc pivotally connected to the concave grating. Separate adjustments are provides for shifting the spectral lines and focussing. A tie rod is used to adjust the focus of the spectral lines. Dectectors are predeterminedly spaced along the arc to simultaneously detect unique spectral lines for analysis of multiple elements contained in a single sample.
