typically as a conformal coating [1 –4]. For quality control of these devices, the thickness of the thin-lms should be moni- . thin films are very limited. Among non-destructive methods, well-known optical methods for measuring the thickness of a thin lm are the ellipsometer and the spectral reectometer. The ellipsometer is a typical means .This method is used to determine the coating optical thickness, defined as the refractive index times the physical thickness, to avoid the need for the coating parameter pre-determination. Initial verification of the optical thickness measurement is achieved by means of a set of uncoated and YSZ-coated fused silica (SiO2) samples. The optical . Accurate coating thickness measurement relies on several fundamental principles that professionals should understand.

Application note A130 - Accurate measurement of optical coating thickness. Most optical coatings are used to enhance reflection or transmission properties of a substrate material within an optical system. They usually consist of one .media and optical coatings. Table 1 What is Spectroscopic Ellipsometry? Spectroscopic Ellipsometry (SE) is an optical technique mainly used to determine film thickness and optical con-stants (n,k) for stru ctures composed of single layer or mul-tilayers. SE is based on the measurement of polarized light.
