    Abstract: PROBLEM TO BE SOLVED: To allow comparison of data measured under different conditions and very simple setting of an initial value of fitting data by even an inexperienced worker such as a beginner.
    SOLUTION: A spectroscopic ellipsometer includes a reference data storage section D1 storing reference data to be compared with measured data, a conversion operation section 73 converting the measured data or the reference data into comparable data so that the measured data are compared with the reference data, and a comparison and determination section 74 comparing the measured data and the reference data made comparable by the conversion operation section with each other and determining a degree of coincidence therebetween.
