Beam shaper [GTH]

GTH-S-4.0-2.0

  • - Square Top Hat
  • - > 95 % efficiency
  • - 100 µm to 5 mm Top Hat width
  • - coatings for UV to IR
  • - 4 mm input beam diameter, 2 mrad fan angle
  • Product sheet

SPECIFICATIONS

SPOT GEOMETRY
Top Hat width full fan angle of 2 mrad
Efficiency > 95% (depends on the coating type)
Homogeneity about ± 5% (rel. to average intensity of the Top Hat plateau)
Depth of the Top Hat shape (DOF) Depends on the optical setup; for example 1.5mm depth using 4.0mm beam diameter, wavelength 532nm and 250mm focal length.
REQUIREMENTS FOR THE USE OF GTH-S-5.0-16.0
Input beam single or multimode laser beam with Gaussian energy distribution
Input beam diameter 4.0 mm @1/e²
Apertures within the optical setup clear aperture along the whole beam path should be at least 2.5x larger than the beam diameter @ 1/e²
INTEGRATION OF GTH-S-5.0-16.0 INTO THE BEAM PATH
Alignment alignment in lateral direction is necessary (translation). Rotating the shaper around the optical axis is helpful to align the orientation of the Top Hat. We recommend our mount HSF02.
Optical equipment required: focusing optic to generate the Top Hat in the focal plane of this optic.

useful: beam expander to firstly adjust the effective beam dia. to the design input beam dia. of GTH-S-4.0-2.0 and secondly adjust the beam dia. to the desired spot size.

helpful: beam profiler to check profiles while aligning.
