Aluminum Foil – Shiny Side

Surface Roughness Aluminum Foil, Shiny Side - Digital Metrology Surface Library

The shiny side of aluminum foil.

This side of the foil has long striations across the surface, whereas the dull side (also in the library) has a lot of fine, speckled detail. The difference all occurs in the very short wavelength domain, around 20 microns—removing a 4th order polynomial as the Reference Geometry reveals this finer texture.
