Lapho unquma phakathi kwelensi ye-plano-convex kanye ne-bi-convex lens, kokubili okubangela ukuba ukukhanya kwesigameko esihlanganisiwe kuhlangane, kuvamise ukufaneleka kakhulu ukukhetha ilensi ye-plano-convex uma ukukhuliswa okuphelele okufunayo kungaphansi kuka-0.2 noma kukhulu kuno-0.2 noma kukhulu kuno-0.2 5. Phakathi kwalawa manani amabili, ama-bi-convex lens ngokuvamile ayakhethwa.
I-silicon inikezela nge-conductivity ephezulu ye-thermal kanye ne-low density. Nokho inebhande eliqinile lokumunca kuma-microns angu-9, ayifanele ukusetshenziswa nezinhlelo zokusebenza zokudlulisela i-CO2 laser. I-Paralight Optics inikeza Amalensi e-Silicon (Si) e-Plano-Convex ayatholakala nge-broadband AR coating elungiselelwe ububanzi obungama-3 µm kuya ku-5 μm obufakwe kuzo zombili izindawo. Lokhu kunamathela kunciphisa kakhulu ukubukeka kwangaphandle kwe-substrate, kunikeze ukudluliswa okuphezulu kanye nokumunca okuncane kulo lonke uhla lwe-AR.
