I-Zinc Selenide (ZnSe)
I-Bi-Concave Lens

Amalensi we-Bi-concave noma i-Double-concave (DCV) anobude bokugxila obunegethivu. Lawa ma-lens ahlukayo angasetshenziswa ukuphambukisa i-collimated beam ekugxilweni kwayo okubonakalayo futhi avame ukusetshenziswa kusandisi somugqa wohlobo lwaseGalile. Zibuye zivame ukusetshenziselwa ukuphambuka noma ukukhulisa ukuhlukana kwe-converging beam. Kuzinhlelo zokubona, kuvamile ukuthi abacwaningi bakhethe okokubona kwabo ngokucophelela ukuze ukuphambuka okwethulwe amalensi obude obuphozithivu kanye nenegethivu kucishe kukhansele. Abanye basebenzisa lawa ma-lens ngamabili ukuze bakhuphule ubude bokugxila obusebenzayo belensi eguqukayo njengelensi ye-meniscus engalungile.

Uma unquma phakathi kwelensi ye-plano-concave kanye nelensi ye-bi-concave, kokubili okwenza ukukhanya kwesigameko kuhluke, kuvame ukufaneleka kakhulu ukukhetha ilensi ye-bi-concave uma isilinganiso esiphelele se-conjugate (ibanga lento lihlukaniswa ngebanga lesithombe) iseduze no-1. Uma ukukhuliswa okuphelele okufunayo kungaphansi kuka-0.2 noma okukhulu kuno-5, ukuthambekela kuwukukhetha ilensi ye-plano-concave esikhundleni.

Amalensi e-ZnSe afaneleka kahle kakhulu ukusetshenziswa namalaser anamandla e-CO2. I-Paralight Optics inikezela ngamalensi e-Zinc Selenide (ZnSe) Bi-Concave noma i-Double-Concave (DCV) atholakala nge-broadband AR coating elungiselelwe ububanzi obungama-8 – 12 μm obufakwe kuzo zombili izindawo. Lokhu kunamathela kunciphisa kakhulu ukubukeka okuphezulu kwendawo engaphansi, kuveza ukudluliswa okumaphakathi okungaphezu kuka-97% kulo lonke uhla lwe-AR. Ukuze uthole ulwazi olwengeziwe mayelana nama-coatings, sicela uhlole Amagrafu alandelayo ukuze uthole izinkomba zakho.
