Abstract
The plasma-enhanced chemical vapor deposition of optical coatings on plastic substrates leads to the formation of a physically thick (≈50–100-nm) interfacial region (or interphase). We propose, based on our earlier spectroellipsometric (in situ and ex situ) and spectrophotometric (ex situ) studies, an optical model for the description of the interphase refractive-index profile n(z). We study in detail the effect of such an interphase on the spectral performance of various optical filters (antireflective V-coat, W-coat, achromatic W-coat, and minus filter). It is shown that considering the inhomogeneous n(z) profile in the design can improve the optical performance of some filters.
