Abstract
Optical inspection techniques often require highlighting of the surface to inspected. A method and apparatus is provided to prepare such surfaces for instrumental inspection by applying a sheet of a solid, deformable film, e.g. a polymeric film or a metal foil, to the surface and then forcing the layer against the surface in a controlled manner so that a contiguous relationship therebetween is attained. The film can bridge pores, roughness and equalize the reflectivity of the surface. The film can usually be removed and reused without affecting the object.
