IZinc Selenide (ZnSe)
IiLensi zeBi-Convex
Nangona iilensi ze-Bi-convex zinciphisa ukuphambuka kwiimeko apho umgama wento kunye nomfanekiso ulingana okanye uphantse ulingane, xa uthatha isigqibo phakathi kwe-bi-convex okanye i-DCX lens kunye ne-plano-convex lens, zombini ezibangela ukuba ukukhanya kwesiganeko esidityanisiweyo kuhlangane. ngokuqhelekileyo kukhethwa ukukhetha i-bi-convex lens yokunciphisa i-aberration ukuba umlinganiselo wento kunye nomgama womfanekiso (umlinganiselo opheleleyo we-conjugate) uphakathi kwe-5: 1 kunye ne-1: 5.Ngaphandle kolu luhlu, iilensi zeplano-convex zihlala zikhethwa.
Iilensi ze-ZnSe zifaneleke ngokukodwa ukusetyenziswa kunye ne-CO2 lasers yamandla aphezulu.IParalight Optics ibonelela ngeZinc Selenide (ZnSe) iiLensi zeBi-Convex ezifumaneka nge-broadband AR yokwambathisa elungiselelwe i-8 ukuya kwi-12 μm yoluhlu lokubonwayo olufakwe kuyo yomibini imiphezulu.Olu gquba lunciphisa kakhulu ukubonakala okuphezulu komphezulu we-substrate, inika usasazo oluyi-avareji ngaphezulu kwe-97% kulo lonke uluhlu lwe-AR yokwambathisa.Jonga ezi Grafu zilandelayo kwiireferensi zakho.
