HORIBA UVISEL 2 Scientific Spectroscopic Ellipsometer


UVISEL 2 Scientific Spectroscopic Ellipsometer

HORIBA Scientific has invented the new generation of scientific spectroscopic ellipsometer that delivers the highest level of performance for nano and micro layer characterization. 
The UVISEL 2 includes the widest range of integrated automated features useful for the investigation of all material family. 
The UVISEL 2 features a patented sample vision coupled with automated spot selection for accurate positioning of the measurement spot and region on the sample. 
The UVISEL 2 integrates the world’s smallest patented achromatic spot size of 35Μm capable of covering a large spectral range from FUV to NIR for measurement of very small sample areas. 
Driven by the DeltaPsi2 software, the UVISEL 2 is simple to operate and has the performance required characterizing all current materials as well as the next generation materials and structures. 
HORIBA Scientific started with what has proven to be the most accurate and sensitive ellipsometer, the UVISEL, and redesigned and improved everything to deliver an instrument with a remarkably higher specification than any other instrument.
