DEFINITION

Classification: 378/84

Monochromator of focusing device:

(under subclass 82) Subject matter including a specific element of its support means for limiting the energy spectrum of a beam of X-rays to a narrow band of energies or for converging a beam of X-rays.

(1) Note. The elements of this subclass comprise crystals and gratings which, by diffraction, spatially disperse X-rays according to their energy. These elements are not the objects of examination as in subclass 71 above but rather are tools for examining something else since their diffraction patterns are known.
