Figure 1
Rowland circle diagram of (a) a point-focusing spectrometer design and (b) a DRR design. In the point-focusing case, the sample and detector must be scanned across the circle to measure the spectrum, but, in the DRR case, the entire spectrum is collected at once with a position-sensitive detector. Placing the detector tangent to the Rowland circle removes source-size broadening effects.
