Abstract
High-density polyethylene (HDPE) is used as a coating for optical elements operating in transmission in the infrared spectrum, which are made up of a material other than polyethylene, such as hygroscopic salt, semiconductor materials, fluorides, chalcogenides, silver halides, and others, so as to exploit the optical properties of HDPE, at the same time keeping the thickness reduced.
