Instrument >> Instrument for Solar Cell >> Auto Spectroscopic Ellipsometer:PH-ASE
                

 

       The PH-ASE spectroscopic ellipsometer  measures thickness, refractive index and extinction coefficient of single films and multilayer stacks. Reflection measurements at different incident angles and transmission measurements can be carried out and combined with ellipsometric data.
 
Product's Feature:
       The spectroscopic ellipsometer is used for thin film and material characterization in R & D. The spectroscopic ellipsometer is designed to meet the requirements in modern research with special emphasis on speed and accuracy for an unmatched variety of applications.
Automatic calibration and Measurement
Measurement of thickness and refractive index of transparent films on absorbing or transparent substrates
Analysis of amorphous and polysilicon films and SOI films
Measurement of optical constants of photoresists
Analysis of organic films
