Iglasi yeQuartz yinto esisiseko kwimveliso yefayibha ebonakalayo kuba inentsebenzo elungileyo yokuhambisa i-UV kunye nokufakwa okuncinci kakhulu kokukhanya okubonakalayo kunye nokukhanya okusondele kwe-infrared. Ngaphandle kwendlela yokwandiswa kobushushu beglasi ye-quartz incinci kakhulu. Ukuzinza kwayo kwemichiza kulungile, kwaye amaqamza, imitya, ukufana kunye ne-birefringence ziyafana nezo zeglasi ebonakalayo ebonakalayo. Yeyona nto ibonakalayo ebonakalayo phantsi kobume obungqongqo.
Ukwahlulahlula ngeempawu ezibonakalayo:
1. (Iglasi ye-Quartz yeGlasi ye-UV Optical) JGS1
Yiglasi yequartz ebonakalayo eyenziwe ngelitye lokwenziwa kunye ne-SiCl 4 njengezinto ezingavuthiyo kwaye inyibilikiswe kukucoceka okuphezulu kwelangatye le-oxyhydrogen. Ke iqulethe isixa esikhulu sehydroxyl (malunga ne-2000 ppm) kwaye inentsebenzo egqibeleleyo yokuhambisa i-UV. Ngokukodwa kwingingqi ye-UV emfutshane, ukusebenza kwayo kokuhambisa kungcono kakhulu kunezinye iintlobo zeglasi. Ixabiso lokuhambisa i-UV kwi-185nm linokufikelela kwi-90% okanye nangaphezulu. Iglasi yequartz eyenziweyo ifumana ukomelela okunamandla kakhulu kwi-2730 nm kwaye ayinabume bamasuntswana. Yimathiriyeli ebonakalayo ebonakalayo kuluhlu lwe-185-2500nm.
2. (Iglasi yeQuartz yeUV ye-UV) JGS2
Yiglasi yequartz eveliswa kukucokiswa kwegesi ngekristale njengezinto ezingavuthiyo, eziqulathe inkunkuma yePPM yentsimbi. Kukho iincopho zokufunxa (umxholo wehydroxyl 100-200ppm) kwi-2730nm, ngomqolo kunye nolwakhiwo lwamasuntswana. Yinto elungileyo kuludwe lwebhendi yomtshangatshangiso eyi-220-2500 nm.
3. (I-Infrared Optical Quartz Glass) JGS3
Luhlobo lweglasi ye-quartz eveliswa sisithando soxinzelelo lwe-vacuum (okt indlela ye-electrofusion) enekristale okanye isanti ye-quartz esulungeke kakhulu njengezinto eziluhlaza eziqulethe ukungcola kwesinyithi kwe-PPM. Kodwa inamabhamu amancinci, ulwakhiwo lwamasuntswana kunye nemiphetho, phantse akukho-OH, kwaye ine-infrared transmittance ephezulu. Ukudluliselwa kwayo kungaphezulu kwe-85%. Uluhlu lwayo lwesicelo ngama-260-3500 nm izinto ezibonakalayo.
Kukho uhlobo lwayo yonke iglasi yequartz ebonakalayo kwiglasi emhlabeni. Ibhendi yesicelo yi-180-4000nm, kwaye iveliswa ngokufakwa kwesigaba seplasma (ngaphandle kwamanzi kunye ne-H2). Izinto eziluhlaza yi-SiCl4 ngokucoceka okuphezulu. Ukongeza isixa esincinci se-TiO2 kunokucoca i-ultraviolet kwi-220nm, ebizwa ngokuba yi-ozone yeglasi ye-quartz yasimahla. Kuba ukukhanya kwe-ultraviolet engaphantsi kwe-220 nm kunokutshintsha ioksijini esemoyeni iye kwi-ozone. Ukuba inani elincinci le-titanium, i-europium kunye nezinye izinto zongezwa kwiglasi ye-quartz, iliza elifutshane elingaphantsi kwe-340nm linokuhluzwa. Ukuyisebenzisa ukwenza ukukhanya kombane kunefuthe lokhathalelo lwempilo kulusu lomntu. Olu hlobo lweglasi lunokuba bubble ngokupheleleyo. Inokuhanjiswa okubalaseleyo kwe-ultraviolet, ngakumbi kwingingqi ye-wave ye-wave emfutshane, ebhetele kakhulu kunazo zonke ezinye iiglasi. Ukuhanjiswa kwi-185 nm yi-85%. Yimpahla ebonakalayo ebonakalayo kwi-185-2500nm band band of light. Ngenxa yokuba olu hlobo lweglasi luqulathe iqela le-OH, ukuhanjiswa kwayo kwe-infrared kuhlwempuzekile, ngakumbi kukho incopho enkulu yokufunxa kufutshane ne-2700nm.
Xa kuthelekiswa neglasi yesiqhelo ye-silicate, iglasi ye-quartz ebonakalayo inokusasazeka kokuhambisa kuwo onke amaza. Kwingingqi ye-infrared, ukuhanjiswa kwembonakalo kukhulu kuneglasi eqhelekileyo, kwaye kwingingqi ebonakalayo, ukuhanjiswa kweglasi ye-quartz nako kuphezulu. Kwingingqi ye-ultraviolet, ngakumbi kummandla omfutshane we-ultraviolet, ukuhanjiswa kwembonakalo kulunge ngakumbi kunezinye iintlobo zeglasi. Ukuhanjiswa kwembonakalo kuchatshazelwa zizinto ezintathu: ukubonakaliswa, ukusasazeka kunye nokufunxwa. Ukubonakaliswa kweglasi ye-quartz ngokubanzi yi-8%, ummandla we-ultraviolet mkhulu, kwaye ummandla we-infrared uncinci. Ke ngoko, ukuhanjiswa kweglasi ye-quartz ngokubanzi akukho ngaphezulu kwe-92%. Ukusasazeka kweglasi ye-quartz kuncinci kwaye kunokungahoywa. Ukufakwa kwe-spectral kuhambelana ngokusondeleyo nokungahlambuluki kweglasi ye-quartz kunye nenkqubo yokuvelisa. Ukuhanjiswa kwebhendi esezantsi kune-200 nm kubonisa isixa somxholo wokungcola kwesinyithi. Ukufunxwa kwi-240 nm kubonisa ubungakanani besakhiwo se-anoxic. Ukufunxwa kwibhanti ebonakalayo kubangelwa bubukho be-ion yentsimbi yotshintsho, kwaye ukufunxwa kwi-2730 nm yincopho yokufunxa yehydroxyl, enokusetyenziselwa ukubala ixabiso lehydroxyl.
