Lapho unquma phakathi kwe-plano-convex lens kanye ne-bi-convex lens, zombili ezibangela ukuba ukukhanya kwesigameko esihlanganisiwe kuhlangane, ngokuvamile kungcono ukukhetha ilensi ye-plano-convex uma ukukhuliswa okuphelele okufunayo kungaphansi kuka-0.2 noma ngaphezulu kuka-5 Phakathi kwalawa manani amabili, amalensi ama-bi-convex ngokuvamile ayakhethwa.
Ngenxa yobubanzi bayo bokudluliswa okubanzi (2 – 16 µm) kanye nezakhiwo zamakhemikhali ezizinzile, i-Germanium ifaneleka kahle izinhlelo zokusebenza ze-laser ye-IR, ihle kakhulu kwezokuvikela, ezempi kanye nasekusetshenzisweni kwezithombe. Kodwa-ke izakhiwo zokudlulisela ze-Ge zizwela kakhulu izinga lokushisa; empeleni, ukumuncwa kuba kukhulu kangangokuthi i-germanium icishe ibe yi-opaque ku-100 °C futhi ayidluliseli ku-200 °C.
I-Paralight Optics inikeza amalensi e-Germanium (Ge) Plano-convex (PCX) atholakala nge-broadband AR coating yobubanzi obungama-8 µm kuya ku-12 μm obufakwe kuzo zombili izindawo. Lokhu kunamathela kunciphisa kakhulu ukubukeka okuphezulu kwendawo engaphansi, kunikeze ukudluliswa okumaphakathi okungaphezu kuka-97% kulo lonke uhla lwe-AR.
