The purpose of optical coatings is to change the reflectivity of optical surfaces. According to the materials and physical phenomena which are used one can in principle distinguish metallic and ...
Researchers used their new technique to fold a glass bar (a), create an optical resonator (b) to achieve helical bending (c) and to create a table with a parabolic reflector (middle, lower row).
