1. A spectrometer comprising:
a detector, a crystal analyzer, and a linear translation stage;
wherein the crystal analyzer is operably attached to a first arm;
wherein the detector is operably attached to a second arm;
wherein the first arm and the second arm are linked at an axis;
wherein the detector moves rotationally around the axis; and
wherein the axis is centered on a Rowland Circle;
wherein the linear transition stage is configured to move the spectrometer from at least one first location to at least one second location, thereby varying a distance between a sample and the crystal analyzer while maintaining a constant angle between the sample and the detector.
