Zinc Selenide
IiLensi zeMeniscus ezimbi

Iilensi zeMeniscus zisetyenziselwa ikakhulu ukujolisa kubungakanani bamabala amancinci okanye ukudibana kwezicelo.Babonelela ngokusebenza okuphezulu kakhulu ngokunciphisa kakhulu ukuphambuka kwe-spherical.I-meniscus engalunganga (i-convex-concave) iilensi, ezibandakanya umphezulu we-convex kunye nomphezulu we-concave kwaye zincinci embindini kunamaphethelweni kwaye zibangele ukuba imitha yokukhanya ihluke, ziyilelwe ukunciphisa ukujikeleza kwe-spherical kwiinkqubo zokukhanya.

Xa isetyenziselwa ukwahlukanisa ukukhanya kwi-applications yokwandisa umqadi, umphezulu we-concave kufuneka ujongane nomqadi ukucutha ukuphambuka okungqukuva.Xa isetyenziswe ngokudibeneyo kunye nenye i-lens, i-meniscus lens engalunganga iya kwandisa ubude bogxininiso kwaye iyancipha i-aperture yamanani (NA) yenkqubo.

Iilensi ze-ZnSe zifanelekile kwisicelo se-CO2 lasers ngenxa yeempawu ezibalaseleyo zomfanekiso kunye nokuchasana okuphezulu kwi-thermal shock.IParalight Optics ibonelela ngeZinc Selenide (ZnSe) iilensi zemeniscus ezimbi, ezi lens zinciphisa i-NA yenkqubo yamehlo kwaye ziyafumaneka nge-broadband anti-reflection coating, elungiselelwe i-8 µm ukuya kwi-12 μm uluhlu lokubonwayo olufakwe kuzo zombini iindawo kunye nezivuno. Usulelo oluyi-avareji olungaphezulu kwe-97% kulo lonke uluhlu lokutyabeka lwe-AR.
