Photoluminescence Mapper

Photoluminescence spectroscopy is a proven, non-destructive, measurement technique for material characterisation. It is used to determine compositions of alloys and material quality as well as the quantification of lattice defects. A PL Mapper is a laser based instrument used to generate maps of several parameters over full wafers by measuring optical luminescence emission from materials excited with energy above their bandgap.
