Marka la go'aaminayo inta u dhaxaysa lens-convex lens iyo lenska bi-convex, labaduba waxay sababaan iftiinka shilka ee isku-dhafan, inta badan waa la door bidaa in la doorto lens-convex haddii weyneynta buuxda ee la doonayo uu ka yar yahay 0.2 ama ka weyn yahay 5 Inta u dhaxaysa labadan qiyam, muraayadaha bi-convex ayaa guud ahaan la door bidaa.
Iyada oo ay ugu wacan tahay baaxaddeeda gudbinta ballaaran (2 - 16 µm) iyo guryaha kiimikada deggan, Germanium waxay si fiican ugu habboon tahay codsiyada laser-ka IR, waxay aad ugu fiican tahay amniga, militariga iyo codsiyada sawirka. Si kastaba ha ahaatee sifooyinka gudbinta Ge ayaa ah kuwo xasaasi u ah heerkulka sare; Dhab ahaantii, nuugista ayaa noqonaysa mid aad u weyn oo germanium ku dhowdahay mugdi 100 ° C oo aan gebi ahaanba gudbin karin 200 ° C.
Paralight Optics waxay bixisaa Germanium (Ge) Plano-convex (PCX) muraayadaha la heli karo oo leh daahan ballaaran AR oo loogu talagalay 8 µm ilaa 12 μm kala duwanaansho muuqaal ah oo lagu kaydiyay labada dusha sare. Dahaarkani wuxuu si weyn u yareynayaa milicsiga sare ee substrate-ka, taasoo keenaysa gudbin celcelis ka badan 97% dhammaan noocyada daahan AR. Ka hubi Garaafyada tixraacyadaada.
