IZinc Selenide (ZnSe)
IiLensi zeBi-Concave

Iilensi ze-Bi-concave okanye i-Double-concave (i-DCV) zinobude bojoliso obungalunganga. Ezi lens ziphambukayo zingasetyenziselwa ukwahlukanisa umqadi odityanisiweyo ukuya kugxininiso lwenyani kwaye ziqhele ukusetyenziswa kwisandisi sohlobo lwaseGalili. Zikwahlala zisetyenziselwa ukuphambuka okanye ukonyusa ukwahlukana komqadi oguqukayo. Kwiinkqubo zamehlo, kuqhelekile ukuba abaphandi bakhethe i-optics yabo ngononophelo ukuze uphambuko oluvezwe ziilensi eziphozithizelayo kunye nenegative-ubude bojoliso malunga nokurhoxisa. Abanye basebenzisa ezi lensi ngazibini ukunyusa ubude obusebenzayo belensi eguqukayo njengelensi ye-meniscus engalunganga.

Xa uthatha isigqibo phakathi kwe-lens yeplano-concave kunye ne-bi-concave lens, zombini ezibangela ukuba ukukhanya kwesiganeko kuhluke, ngokuqhelekileyo kulungele ukukhetha i-lens ye-bi-concave ukuba i-absolute conjugate ratio (umgama wento eyahlulwe ngumgama womfanekiso) isondele ku-1. Xa ukwandiswa okupheleleyo okufunwayo kungaphantsi kwe-0.2 okanye kukhulu kuno-5, utyekelo kukukhetha ilensi yeplano-concave endaweni.

Iilensi ze-ZnSe zifaneleke ngokukodwa ukusetyenziswa kunye ne-CO2 lasers yamandla aphezulu. IParalight Optics ibonelela ngeZinc Selenide (ZnSe) iiLensi zeBi-Concave okanye i-Double-Concave (DCV) ezifumaneka nge-broadband AR coating elungiselelwe i-8 - 12 μm yoluhlu lwembonakalo ediphozithwe kuzo zombini iindawo. Oku kugquma kunciphisa kakhulu ukubonakala okuphezulu komphezulu we-substrate, inika usasazo oluyi-avareji ngaphezulu kwe-97% kulo lonke uluhlu lwe-AR yokwambathisa. Ngolwazi oluthe kratya malunga neengubo, nceda ujonge ezi Grafu zilandelayo kwiireferensi zakho.
