What is a Top Hat Beam Profile?

A top hat laser beam is a laser beam whose intensity profile is flat and uniform, with sharp edges where the energy drops rapidly to zero. Such a flat-top energy distribution is called a top hat energy distribution. This beam shape is highly useful in many industrial laser applications. The top hat energy distribution can … Continue reading

Using Top Hat Beam Shaper to Cut Film

The rising demand for Organic Light Emitting Diode (OLED) screens resulted in a search for better laser-based film cutting solutions that require higher power and better processing quality. One of the problems that manufacturers are currently facing is reducing the Heat-Affected Zone (HAZ) next to the edges of the cut. One solution to mitigate this … Continue reading
