Amalensi e-Plano-concave asebenza kahle uma into nesithombe kuku-absolute conjugate ratios, okukhulu kuno-5:1 noma ngaphansi kuka-1:5. Kulokhu, kungenzeka ukunciphisa ukuphuma okuyindilinga, i-coma, nokuhlanekezela. Ngokufanayo namalensi e-plano-convex, ukuze kuzuzwe ukusebenza kahle okuphezulu indawo egobile kufanele ibhekane nebanga lento enkulu kunazo zonke noma i-conjugate engapheli ukuze kuncishiswe ukuphuma okuyindilinga (ngaphandle uma isetshenziswa ngamalaser anamandla amakhulu lapho lokhu kufanele kubuyiselwe emuva ukuze kuqedwe ukuba nokwenzeka kwe-virtual aberration. gxila).
Amalensi e-ZnSe afaneleka kakhulu ukusetshenziswa namalaser anamandla e-CO noma e-CO2. Ukwengeza, bangase banikeze ukudluliswa okwanele endaweni ebonakalayo ukuze bavumele ukusetshenziswa kwe-beam yokuqondanisa ebonakalayo, nakuba ukucabangela emuva kungase kubonakale kakhudlwana. I-Paralight Optics inikeza Amalensi e-Zinc Selenide (ZnSe) e-Plano-Concave (PCV) atholakala nge-broadband AR coating elungiselelwe u-2 µm – 13 μm noma 4.5 – 7.5 μm noma 8 – 12 μm ububanzi bokubuka obufakwe kuzo zombili izindawo. Lokhu kunamathela kunciphisa kakhulu ukubukeka okuphezulu kwendawo engaphansi, kunikeze ukudluliswa okumaphakathi okungaphezu kuka-92% noma u-97% kulo lonke uhla lokumboza lwe-AR.
