Beam shaper directly in front of focusing optic/objective (Top Hat size >100 μm). Top Hat size is determined by focal length (f) of focusing optic/ 2.2 objective and can be calculated as follows: ·f 1000 free aperture 2.2x beam diameter @1/e² additional focusing lens/objective collimated input beam Top-Hat size 1.65 × 1.65 mm² full fan angle 2.2 mrad distance = f1 = 50 mm distance = f2= 750 mm distance => infinity Top-Hat...

Optical Systems Gauss-to-Top-Hat Beam Shaping Lens Working distance is given by focal length of additional lens which is always needed. Top Hat appears always at focal plane of additional lens. For instance if an additional lens f = 100 is used, Top Hat appears at 100 mm behind additional lens. So GTH-3.6-1.75FA could be easily put in front of objectives for example. The distance between GTH-3.6-1.75FA and additional lens is not critical (up to several tens of centimeters). The full fan angle of Top-Hat generation for GTH-3.6-1.75FA is 1.75 mrad. This leads to Top-Hat sizes: – 88×88 µm for lens...
