Surface light voltage spectrometer

 
 
 

 

 

 

 

 

 

 

Surface photovoltage (SPV) spectroscopy is one of the most sensitive methods for studying the properties of solid surfaces (approximately l08 q/cm2). Its sensitivity is several orders of magnitude higher than that of XPS and Auger electron energy spectrum. It is simple to operate and has good reproducibility.

 

 

 

Surface photovoltage spectrum measurement is a key measurement uncertainty factors in the stability of light source, to this end, our company special offer of 500 w xenon lamp light source for high stability, and greatly improve the measurement precision.



 

 

The system consists of xenon light source, automatic scanning monochromator, fiber beam, phase-locked amplifier, optical chopper, darkroom and data acquisition software.
