Description
FBSR series Top Hat beam shapers are single-piece optical elements designed for the generation of round Top Hat profiles. FBSR beam shapers are so-called focal beam shapers and can generate a Top Hat profile in the focal plane of nearly any focusing optics. Each FBSR lens is designed for a fixed input beam diameter (@1/e²) and specific operation wavelength. FBSR beam shaper can be combined with any objective or F-Theta lens, it can be integrated into the beam path at nearly any position, even in front of or within a beam expander / telescope.
FBSR generate Top Hat spots with long depth of focus (DOF), which is about 30% of the Rayleigh length compared to a Gaussian spot in a similar optical setup. Within this range the Top Hat profile doesn’t change and shows nearly constant peak intensity.
The width of the Top Hat spot generated by FBSR is approximately 1.5 times larger than the diffraction-limited Gaussian spot size. The size of the Top Hat size depends on the focal length of the focusing optics (f), the beam diameter @1/e² (d), and the operation wavelength (λ). The achieved Top Hat size is typically smaller than 100 µm, and can easily be scaled by using different additional focusing optics.
The approximate size of the Top Hat can be calculated by the formula:
2 * λ * f / d or λ / NA, where NA is the numerical aperture of the focused beam.
