Collimator for fiber optics
INEL
An associated filter (depending on wavelength) could limit the energy band of the spectrum of emission; then Kbeta radiation could be largely decreased. Up to now, different types of collimation are available.
If the collimator is directly linked to the source, the primary beam is poly chromatic. Associated with a graphite monochromator first or a parabolic mirror (without filters), the band width in energy becomes much more defined.
