Ingilazi ye-Quartz yinto eyisisekelo yokukhiqizwa kwe-fiber optical ngoba inokusebenza okuhle kokudlulisa i-UV kanye nokumuncwa okuphansi kakhulu kokukhanya okubonakalayo nokukhanya okuseduze kwe-infrared. Ngaphandle kwe-coefficient yokwanda okushisayo kwengilazi ye-quartz incane kakhulu. Ukuzinza kwayo kwamakhemikhali kuhle, futhi amagwebu, imivimbo, ukufana kanye ne-birefringence kufana nokwengilazi ejwayelekile yokukhanya. Kuyinto ebonakalayo enhle kakhulu ngaphansi kwemvelo enokhahlo.
Ukuhlukaniswa ngezindawo ezibonakalayo:
1. (Ingilazi ye-Quartz ye-UV Optical Ekude) JGS1
Kuyingilazi ye-quartz ebonakalayo eyenziwe ngamatshe okwenziwa nge-SiCl 4 njengezinto eziluhlaza futhi encibilikiswa ilangabi eliphezulu le-oxyhydrogen. Ngakho-ke iqukethe inani elikhulu le-hydroxyl (cishe ngo-2000 ppm) futhi inokusebenza okuhle kakhulu kokudluliswa kwe-UV. Ikakhulukazi esifundeni se-wave wave esifushane, ukusebenza kwayo kokudlulisa kungcono kakhulu kunezinye zonke izinhlobo zengilazi. Izinga lokudluliswa kwe-UV ku-185nm lingafinyelela kuma-90% noma ngaphezulu. Ingilazi yokwenziwa ye-quartz ithola ukuphakama okunamandla kakhulu ku-2730 nm futhi ayinakho ukwakheka kwezinhlayiyana. Kuyinto ebonakalayo enhle kakhulu ebangeni le-185-2500nm.
2. (Ingilazi ye-UV Optical Quartz) JGS2
Ingilazi ye-quartz ekhiqizwa ukucwalwa kwegesi nge-crystal njengezinto ezingavuthiwe, equkethe inqwaba yokungcola kwensimbi kwe-PPM. Kukhona iziqongo zokumunca (okuqukethwe kwe-hydroxyl 100-200ppm) ku-2730nm, ngomugqa wesakhiwo kanye nezinhlayiya. Kuyinto enhle ebangeni le-wave band elingu-220-2500 nm.
3. (I-Infrared Optical Quartz Glass) JGS3
Luhlobo lwengilazi ye-quartz ekhiqizwa nge-vacuum pressure furnace (ie electrofusion method) enekristalu noma isihlabathi se-quartz esine-high-purity njengempahla eluhlaza equkethe inqwaba yokungcola kwensimbi kwe-PPM. Kepha inamabhamuza amancane, ukwakheka kwezinhlayiyana nemiphetho, cishe akunayo i-OH, futhi ine-infrared transmittance ephezulu. Ukudluliselwa kwayo kungaphezu kwama-85%. Uhla lwayo lokusebenza luyi-260-3500 nm izinto ezibonakalayo.
Kukhona nohlobo lwayo yonke ingilazi ye-wave band optical quartz emhlabeni. Ibhendi yokufaka isicelo ingu-180-4000nm, futhi ikhiqizwa nge-plasma phase phase deposition (ngaphandle kwamanzi ne-H2). Okusetshenziswayo yi-SiCl4 ngokuhlanzeka okuphezulu. Ukungeza inani elincane le-TiO2 kungahlunga i-ultraviolet ku-220nm, ebizwa ngengilazi ye-quartz yamahhala ye-ozone. Ngoba ukukhanya kwe-ultraviolet ngaphansi kuka-220 nm kungashintsha umoya-mpilo emoyeni ube yi-ozone. Uma kufakwa inani elincane le-titanium, i-europium nezinye izinto engilazini ye-quartz, igagasi elifushane elingaphansi kwama-340nm lingahlungwa. Ukuyisebenzisa ukwenza umthombo wokukhanya kagesi kunomphumela wokunakekelwa kwezempilo esikhunjeni somuntu. Lolu hlobo lwengilazi lungaba mahhala ngokuphelele. Ine-ultraviolet transmittance enhle kakhulu, ikakhulukazi esifundeni se-wave wave esifushane, esingcono kakhulu kunazo zonke ezinye izibuko. Ukudluliselwa ku-185 nm kungama-85%. Kuyinto ebonakalayo enhle kakhulu ku-band ye-wave yokukhanya engu-185-2500nm. Ngoba lolu hlobo lwengilazi luqukethe iqembu le-OH, ukuthunyelwa kwalo kwe-infrared kubi, ikakhulukazi kunesiqongo esikhulu sokumunca esiseduze ne-2700nm.
Uma kuqhathaniswa nengilazi ejwayelekile ye-silicate, ingilazi ye-quartz ebonakalayo inokusebenza okuhle kakhulu kokudlulisa kuyo yonke i-wavelength. Esifundeni se-infrared, ukuhanjiswa kwe-spectral kukhulu kunokwengilazi ejwayelekile, futhi esifundeni esibonakalayo, ukuhanjiswa kwengilazi ye-quartz nakho kuphakeme. Esifundeni se-ultraviolet, ikakhulukazi esifundeni se-wave wave esifushane, ukuhanjiswa kwe-spectral kungcono kakhulu kunezinye izinhlobo zengilazi. Ukudluliswa kwe-spectral kuthintwa yizinto ezintathu: ukukhombisa, ukusakazeka nokumunca. Ukuboniswa kwengilazi ye-quartz imvamisa kungu-8%, isifunda se-ultraviolet sikhulu, kanti isifunda seso lefoni sincane. Ngakho-ke, ukuhanjiswa kwengilazi ye-quartz ngokuvamile akukho ngaphezu kwama-92%. Ukuhlakazeka kwengilazi ye-quartz kuncane futhi kunganakwa. Ukumuncwa kwe-spectral kuhlobene kakhulu nokungahlanzeki kwengilazi ye-quartz kanye nenqubo yokukhiqiza. Ukudluliswa ebhandeni elingaphansi kuka-200 nm kubonisa inani lokuqukethwe kokungcola kwensimbi. Ukumuncwa ku-240 nm kubonisa inani lesakhiwo se-anoxic. Ukumuncwa ebhendi ebonakalayo kudalwa ukutholakala kwama-ayoni wensimbi aguqukayo, futhi ukumuncwa ngo-2730 nm yisiqongo sokumunca se-hydroxyl, esingasetshenziswa ukubala inani le-hydroxyl.
