2.3.3.1.43. NXmonochromator¶
Status:
base class, extends NXcomponent
Description:
A wavelength defining device. ...
A wavelength defining device.
This is a base class for everything which selects a wavelength or energy, be it a monochromator crystal, a velocity selector, an undulator or whatever.
The expected units are:
wavelength: angstrom
energy: eV
Symbols:
No symbol table
- Groups cited:
NXaperture, NXcrystal, NXdata, NXgeometry, NXgrating, NXoff_geometry, NXvelocity_selector
