Refractive Beam Shaper – BS Series
The beam shaper’s function is to transform the Gaussian profile of a light source (commonly laser) to a Top-Hat profile.
The design is based on transmissive model that can be used with maximum input beam size of 4.6mm and output of 8mm. The output beam after the beam shaper is collimated, thus it can be used with normal lenses. We are open for other wavelength requirements based on your specific applications.
It is commonly used for drilling and marking applications. The Top Hat profile cut or mark result has higher quality than the Gaussian. It is widely used in the industry.
Focal Type Beam Shaper – BSFL Series
The focal type beam shaper comprises a focusing lens to acquire a top hat focused spot at the target plane and able to achieve sub-micron level with good uniformity. One of the advantages of focal type beam shaper over other designs is that it provides flexibility to the users as they can vary to their desired spot size accordingly by changing the focusing lens. Furthermore, this focal type beam shaping system has extended the working range whereby a focusing lens can be placed at any distance behind the beam shaping system without affecting the top hat spot quality.
The figure shows the microscopic views of focal spot with and without focal beam shaper. Focal beam shaper is able to produce extended depth of focus with straight wall edge as what we can see in the simulated top hat profile. While without focal beam shaper, we can see the kerf width of focal Gaussian spot and substantial heat affected zone.
Surface heat treatment, solar cell scribing, via-hole drilling, laser ablation, dicing, micro-machining, marking and cutting.
