SE 900-50 红外光谱椭偏仪替代型号
Basics The ellipsometer measures in reflection mode the optical response of a sample using polarized light.
The sample properties change the polarization state of the reflected light. Amplitude ratio and phase difference of the Fresnel reflection coefficients rpand rsare used to investigate material composition, molecule orientation, film thickness and optical constants of single films and layer stacks.
