By introducing the FBS beam shaper element at nearly any position into the beam path (even in front of or within a beam expander) a focused, diffraction limited Gaussian beam profile at focal plane will be transformed into a near diffraction limited homogeneous Top Hat profile. The achievable Top-Hat size just depends on used wavelength (λ) and numerical apperture (NA) of focusing system and is given by ~ λ/NA. The FBS beam shaper can be introduced into the beam path at any desired position.
