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.

|
* 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.
