Focal Type Beam Shaper

Beam Shaper

BSFL series Focal type beam shaper converts a collimated Gaussian beam to a collimated output beam. This output beam is not a flat top profile while it is designed to achieve flat top profile at target plane.

This beam shaper has to be used incorporated with a focusing lens or diffraction-
limited performance lens to acquire a flat top focused spot at vicinity of target
plane. The flat top spot size is able to achieve sub-micron level and good
uniformity.

Focusing lenses are available at different Focal length for your specific application upon request.

Applications

Surface heat treatment, solar cell scribing, via hole drilling, laser ablation, dicing, micromachining, marking and cutting.

Specifications

Beam Mode: TEM00
M2: <1.2
Beam Ellipticity: ~0.98-1
