关键词We have investigated the effect of transparent thin film while mapping its surface profile by using vertical scanning white light interferometer. Our theory analysis showed that multiple reflections taking place within the transparent thin film result in an extra phase change. The simulation and experiment results revealed that this extra phase change is also related to the thickness of thin film the numerical number of microscope interferometer objective and the spectral distribution of light source. As a result of extra phase change the interferogram has some deviation in its shape or two interference fringes may appears while the thickness of thin film is large.
