UV e Fused Silika (JGS1)
Lilense tsa Bi-Convex
Re sebelisa lisebelisoa tse lekanang tsa Sechaena tsa silica e kopantsoeng, haholo-holo ho na le mefuta e meraro ea silika e kopantsoeng Chaena: JGS1, JGS2, JGS3, e sebelisetsoa ts'ebeliso e fapaneng. Ka kopo sheba lintlha tse latelang tsa thepa:
JGS1 e sebelisoa haholo-holo bakeng sa optics ho UV le sebaka se bonahalang sa wavelength. Ha e na li-bubble le li-inclusions. E lekana le Suprasil 1&2 le Corning 7980.
JGS2 e sebelisoa haholo-holo e le karoloana ea liipone kapa li-reflectors, kaha e na le li-bubble tse nyenyane ka hare. E lekana le Homosil 1, 2 & 3.
JGS3 e bonaletsa dibakeng tsa ultraviolet, tse bonahalang le infrared spectral, empa e na le dipudula tse ngata ka hare. E lekana le Suprasil 300.
Paralight Optics e fana ka UV kapa IR-Grade Fused Silica (JGS1 kapa JGS3) Bi-Convex Lenses tse fumanehang ka boholo bo fapaneng, ebang ke lilense tse sa koaeloang kapa tse nang le ts'ebetso e phahameng ea multilayer antireflection (AR) e ntlafalitsoeng bakeng sa mekhahlelo ea 245-400nm, 350-700nm, 650-1050nm, 1050-1700nm e behiloeng holim'a libaka tseo ka bobeli, seaparo sena se fokotsa haholo ponahatso ea karoloana e ka tlase ho 0.5% ka holim'a sebaka sohle sa AR bakeng sa li-angles of incidence (AOI) pakeng tsa 0 ° le 30 °. Bakeng sa lisebelisoa tsa mahlo tse reretsoeng ho sebelisoa ka mahlakoreng a maholo a liketsahalo, nahana ka ho sebelisa seaparo se tloaelehileng se ntlafalitsoeng ka 45° angle ea ketsahalo; seaparo sena se tloaelehileng se sebetsa ho tloha ho 25 ° ho ea ho 52 °.
