Zinc Selenide
I-Meniscus Lens Engalungile
Uma isetshenziselwa ukuphambukisa ukukhanya ezinhlelweni ezinwetshwayo ze-beam, indawo eqondile kufanele ibhekane ne-beam ukuze kuncishiswe ukuphuma okuyindilinga.Uma isetshenziswa ihlanganiswe nenye ilensi, ilensi ye-meniscus engeyinhle izokhuphula ubude bendawo futhi yehlise indawo yokuvula izinombolo (NA) yesistimu.
Amalensi e-ZnSe alungele ukusetshenziswa kwe-CO2 lasers ngenxa yezici ezinhle kakhulu zokucabanga kanye nokumelana okuphezulu nokushaqeka okushisayo.I-Paralight Optics inikeza amalensi e-meniscus e-Zinc Selenide (ZnSe) anegethivu, lawa ma lens ehlisa i-NA yesistimu yokubona futhi atholakala nge-broadband anti-reflection coating, ethuthukiselwe ububanzi obuyi-8 µm kuya ku-12 μm obufakwe kuzo zombili izindawo kanye nesivuno. ukudluliswa okumaphakathi okungaphezu kuka-97% kulo lonke uhla lokumboza lwe-AR.
Izici:
Okubalulekile:
I-Zinc Selenide (ZnSe)
Inketho yokuhlanganisa:
Engagqotshiwe noma ene-Antireflection Coatings
Ubude bokugxila:
Itholakala kusuka -40 kuya -1000 mm
Isicelo:
Ukunciphisa i-NA ye-Optical System
Imininingwane Ejwayelekile:
Umdwebo Wezithenjwa we
I-Meniscus Lens Engalungile
f: Ubude bokugxila
fb: Ubude beFocal Emuva
R: I-Radius of Curvature
tc: Ubukhulu obuphakathi
te: Ukujiya komphetho
H”: Emuva Indiza Eyinhloko
Qaphela: Ubude bokugxila bunqunywa kusukela endizeni eyinhloko engemuva, engahambelani nogqinsi lomkhawulo.
