Teine ala of application for plastic optics is flight hardware. For example, in head-up display (HUD) applications, the weight of components is an important consideration. Plastic optics are ideal for HUD applications. Like many other complex optical systems, anti-reflection katted are required in HUDs to avoid stray light from stray emissions. kuigi väga peegeldav metall kiled ja mitmekihiline oksiid täiustamine kiled saab ka olla rakendatav, tööstus ikka vajadused to jätkata et arendada uued tehnoloogiad to to plast optilised komponendid sisse rohkem esilekerkivad rakendused.

Plastic optics can be used in most visible light applications. For other NUV and NIR applications, transmission wavelengths of commonly used materials such as acrylic (excellent clarity), polycarbonate (best impact strength) and cycloolefins (high heat resistance and durability, low water absorption) The range is 380~100nm). Coatings are added to the surface of plastic optical components in order to improve their transmission or reflection performance and increase durability. Thick layer coatings (typically about 1 μm thick or more) act primarily as a protective layer, while also improving adhesion and robustness for subsequent thin layer coatings. Thin layer coatings include silicon dioxide (SiO2), tantalum oxide, titanium oxide, aluminum oxide, niobium oxide, and hafnium oxides (SiO2, Ta2O5, TiO2, Al2O3, Nb3O5, and HfO2); typical metal mirror coatings are aluminum (Al) , silver (Ag) and gold (Au). Fluorides or nitrides are rarely used for coatings because of the higher heat required to obtain good coating quality, which is inconsistent with the low heat deposition conditions required for coating plastic components.
