ABSTRACT:
A scanning monochromator or spectrometer having a reflecting grating whose curvature in the meridian plane is equal to the curvature of a circle upon which the source, detecting means and grating lie and whose lines are ruled with a frequency which varies systematically and directly in proportion to the distance of the lines from a point of origin on the track as determined by the geometry of the equipment, and gratings therefor.
