          Beam Shaper Top Hat Square at 532nm

 

 

 

 

General Description: Beam Shaper module for high-power lasers with wavelengths in the near infrared. The modules are of solid industrial design and can easily be integrated in the beam path of the collimated laser light or connected to fibre coupled lasers. Homogeneous top hat light fields with various dimensions are generated at the working distance of the modules.

  • Mountings: SMA-905 or LD 80

  • Fibre diameter: 100μm 600μm

* The uniformity depends on the laser beam parameters: M2 > 20 is recommended. Imax and Imin denote the maximum and minimum intensity in the uniform field, respectively.

** Ifield,hom / Ifield,total denotes the ratio of the integrated power in the homogeneous field versus the total power at the field plane.
