The PH50DL Zoom Optic laser head transforms the high-power output of a diode laser into a 2D homogenized rectangular focus point with a top-hat profile whose length and width are independently software adjustable on the fly. The PH50DL laser head is used for heat treating, hardening, cladding, laser assisted bonding, μLED bonding and tape laying. The head's advantage is that it can dynamically change the spot size to optimize laser tempering processes for each application. The head allows easy integration with process monitoring capabilities, including pyrometer control.
