New product: Gauss-to-Top Hat beam shaping lens
New refractive "freeform" lens GTH-3.6-1.75 for Gauss-to-Top Hat transformation
The beam shaper lens GTH-3.6-1.75 can be introduced nearly at any position into beam path. Even in front of or within a beam expander. It's just to consider that the beam diameter at the position of the shaper is 3.6 mm@1/e². By focusing the shaped beam user can realize homogeneous Top Hat profiles with a size of 3.2 µm/NA. NA represents the numerical aperture of focused beam. Therefore is possible to generate Top Hat sizes in a range of 30 µm to 1000 µm with a single GTH-3.6-1.75 beam shaper lens.
