Top Hat

TOPAG offers different Top Hat beam shapers for generation of round or rectangular/square Top Hat profiles. All beam shapers are so called focal beam shapers and generate the Top Hat profile in focal plane of nearly any focusing optics. Difference is the size of the generated Top Hat profile. The Top Hat size can be easily scaled by using additional different focusing optics (respectively the focal length)

The beam shaper of the GTH series can be used to generate rectangular/square Top Hats. Top Hat size is typically bigger than 100µm up to several centimeters.

The FBS series can be used to generate Top Hats sizes which are typically smaller than 100µm. There are different versions for rectangular/square or round Top Hat profiles.
