Layered Polymers-Transmission and Reflection

Synthetic layered polymers are commonly used in art and cultural heritage products. Such materials in art pieces are subject to deterioration such as cracking, deformations, or discolorations [69]. There is an oxygen-barrier film (FR-7750, 

Scale bar in (a) is 20 pm. (c) and (d) show the results of deconvolution of the data used to generate (a) and (b). (e) and (f) show the analogous data of (a) and (b) as measured with the 36x objective. Scale bar in (e) is 20 pm. (g,h) show the results of deconvolution of the data used to generate (c,d).
