The invention relates to a wavelength selector for the soft X-ray range and/or the extreme ultraviolet range. Said wavelength selector comprises at least two reflectors that are optically connected in series in such a manner that a beam incident on the first reflector runs in a substantially ...
referring to the range of colors observed when white light was dispersed through a prism. Soon the term referred to a plot of light intensity or power as a function of frequency or wavelength, also known as a spectral density plot.

Synchrotron-based X-ray techniques tend to be well adapted to the analysis of E.T. samples in the 1–100 µm size range, depending of course on the photon wavelength and on the studied process. This is why they have been successfully applied both to Stardust and Hayabusa samples. ...

[X射线衍射-经典课件]-24:X-Ray Diffraction-宾夕法尼亚大学.pptx,X线(X射线)是一种波长很短的电磁波,波长在~10nm到~0.1nm左右,有很大的穿透能力,能使照相胶片感光,使某些物质发荧光,并能使气体游离。对机体细胞有很强的破坏作用。X线被广泛应用于临床诊断和治疗,
It is necessary to use a selection of different crystals, of different latticespacing, to get effective coverage of the entire X-ray wavelength range of interest for general-purpose analysis. Hence EPMAs typically have several (three or more) spectrometers, each fitted with a different crystal. ...
is well known that X-ray spectra are sensitive to the chemical states of the emitting atoms and are of great use for studying the atomic and electronic structure in materials. Such a study covering a wide range of elements will be of help in making correlations between theory and experiment...
