Thickness of 10 μm thick food wrapping film (polyvinylidene

chloride) was measured.

Note:

Principle of film thickness measurement:

In film thickness measurement utilizing white light interferometry,

an interference spectrum resulting from internal reflections

between the front and back surfaces of a film is obtained.

The film thickness can then be determined by calculation from

the spectral peak count, wavelength range, refractive index of

film and incident light angle.
