Hāʻawi ʻo Silicon i ka conductivity thermal kiʻekiʻe a me ka haʻahaʻa haʻahaʻa. Eia nō naʻe, loaʻa iā ia kahi puʻupuʻu absorption ikaika ma 9 microns, ʻaʻole kūpono ia no ka hoʻohana ʻana me nā noi hoʻoili laser CO2. Hāʻawi ʻo Paralight Optics iā Silicon (Si) Plano-Convex Lenses i loaʻa me kahi uhi AR broadband i hoʻopaʻa ʻia no ka 3 µm a i 5 μm spectral range i waiho ʻia ma nā ʻaoʻao ʻelua. Hoʻemi nui kēia uhi i ka nānā ʻana o ka ʻili o ka substrate, e hāʻawi ana i ka hoʻouna kiʻekiʻe a me ka liʻiliʻi o ka absorption ma luna o ka laulā AR coating āpau. E nānā i nā kiʻi no kāu mau kuhikuhi.
