Solar cells checked by high power diode laser line generator

Keywords:laser line generators  homogenizers  AMOLED  photoluminescence spectroscopy 

LIMO's has released its latest laser line generations which support the processing, organising and refining of surfaces. The latest laser line generators rely on lenses and so-called homogenizers.

There are already line lasers with short lines (450 watts, 12 times 0.1 square millimeter) serving as inexpensive standard solutions in the thermal processing of silicon, for example. The generators structuring AMOLED (active matrix organic light emitting diode) displays with 80mm long lines supply several kilowatts of power. This technology is designed to add to the changing energy policy: a line laser (40 watts of power, 808nm wavelength and 165mm line length) is able to scrutinise solar cells using the so-called photoluminescence spectroscopy.
