One method is to use a monochromator, for example a Czerny Turner design, with an optical detector placed at the output slit.
32.
The task of the monochromator is to reduce the energy of the passing electrons to some eV due to the help of electron lenses.
33.
YB 66 is used as a soft-X-ray monochromator for dispersing 1 2 keV synchrotron radiation at some synchrotron radiation facilities.
34.
An ultrafast monochromator uses a second diffraction grating to compensate time delays introduced to the pulse by the first grating and other dispersive optical elements.
35.
The lines of communication between monochromator, detector output, and computer should be optimized to ensure the desired metrics and features are being used.
36.
The spectrometer consists of either a monochromator ( scanning ) or a polychromator ( non-scanning ) and a photomultiplier or CCD detector respectively.
37.
The purpose of this system is to focus the electrons on the entrance of the monochromator unit, to get a high initial electron flux.
38.
A high intensity ultrashort pulse will generate an array of harmonics in the medium; a particular harmonic of interest is then selected with a monochromator.
39.
To correct this, a beam splitter can be applied after the excitation monochromator or filter to direct a portion of the light to a reference detector.
40.
Before being used in a beamline endstation, the light is collimated before reaching a monochromator or series of monochromators to get a single and fixed wavelength.
