Abstract: PURPOSE:To attain reduction of the cost and extension of the use of an apparatus for analyzing polarization, to facilitate maintenance thereof, to make it correspond also to an optical constant of a complex number and to improve the precision and reliability of measurement by substituting electromagnetic parts for mechanical parts of the apparatus, considering that these parts hinder miniaturization of the apparatus. CONSTITUTION:A semiconductor laser 1 is used as a light source and an incident light on a sample 5 is subjected to a current control to be of two wavelengths. An acoustooptical element 3 is used for a polarizing system and an angle of incidence is changed according to the wavelength. A Faraday element 6 being used for an analyzing system, the plane of polarization of a reflected light from the sample 5 is thereby rotated and a phase is measured. A photodiode 7 is used for a detector as well for miniaturization. The film thickness and the optical constant of the sample are calculated from the amount of change in a phase difference and an amplitude ratio.
