Ibisobanuro bya LiF
LiF (lithium fluoride) insimburangingo yerekeza ku bikoresho bikoreshwa nk'ishingiro cyangwa inkunga mu buryo butandukanye bwo kohereza firime mu buryo bwa optique, fotonike na microelectronics.LiF ni kristu ibonerana kandi ikingira cyane hamwe na bande yagutse.
LiF insimburangingo ikoreshwa muburyo bwa firime yoroheje kubera gukorera mu mucyo mu karere ka ultraviolet (UV) no kurwanya ubushyuhe n’imiti.Birakenewe cyane cyane mubisabwa nka optique ya coating, gushira firime yoroheje, spekitroscopi na microscopi ya electron.
LiF insimburangingo isanzwe ihitamo nkibikoresho byububiko kuko bifite uburyo buke bwo kwifata murwego rwa UV kandi biroroshye neza kubipimo nyabyo kandi byuzuye.Byongeye kandi, LiF igaragaza ituze ryiza ku bushyuhe bwo hejuru kandi irashobora kwihanganira uburyo bwinshi bwo kubika nko guhumeka ubushyuhe, gusohora, hamwe na epitaxy ya molekile.
Imiterere ya LiF substrate ituma bikenerwa cyane cyane mubisabwa muri UV optique, lithographie, na X-ray kristu.Kurwanya kwinshi kubintu bidukikije no gutuza imiti bituma bakora ibikoresho bitandukanye mubushakashatsi butandukanye no gukoresha inganda.
Ibicuruzwa bifitanye isano
LiF (lithium fluoride) izwi cyane kubera ibyiza bya infragre (IR) nkibikoresho byiza bya Windows na lens.Hano hari ingingo zingenzi zerekeye kristu ya optique ya LiF2:
1. Gukorera mu mucyo: LiF2 yerekana gukorera mu mucyo mu karere ka infragre, cyane cyane mu burebure bwo hagati na infragre-intera ndende.Irashobora kohereza urumuri muburebure bwumurambararo wa 0.15 mm kugeza kuri 7 mm, bigatuma bikwiranye nuburyo butandukanye bwa infragre.
2Ibi bituma ikwirakwizwa ryinshi bityo ikwirakwiza neza imirasire yimirasire.
3. Indangantego yo kwangirika cyane: LiF2 ifite igipimo cyinshi cyo kwangirika muburebure bwa infragre.Uyu mutungo utuma igenzura neza nogukoresha urumuri rwa infragre, bigatuma rufite agaciro kubishushanyo mbonera bigomba kwibanda no kugorora imirasire yimirasire.
4. Umuyoboro mugari: LiF2 ifite umurongo mugari wa 12,6 eV, bivuze ko bisaba ingufu nyinshi kugirango utangire inzibacyuho.Uyu mutungo ugira uruhare mu gukorera mu mucyo no kwinjizwa gake muri ultraviolet no mu turere twa infragre.
5. Ubushyuhe bwumuriro: LiF2 ifite ubushyuhe bwiza bwumuriro, butuma ishobora guhangana nubushyuhe bwo hejuru nta kwangirika kwimikorere.Ibi bituma bikwiranye na porogaramu zirimo guhura nubushyuhe bwo hejuru, nka sisitemu yo gufata amashusho yumuriro cyangwa sensor ya infragre.
6. Kurwanya imiti: LiF2 irwanya imiti myinshi, harimo aside na alkalis.Ntabwo ikora cyangwa ngo iteshuke byoroshye imbere yibi bintu, byemeza igihe kirekire kandi cyizewe cya optique ikozwe muri LiF2.
7. Birefringence nkeya: LiF2 ifite birefringence nkeya, bivuze ko itagabanya urumuri muri leta zitandukanye.Uyu mutungo ni ingenzi mubisabwa bisaba ubwigenge bwa polarisiyasi, nko muri interferometrie cyangwa ubundi buryo bwiza bwa optique.
Muri rusange, LiF2 yubahwa cyane kubikorwa byayo byiza muri infrarafarike, bigatuma iba ibikoresho byagaciro kuri Windows na lens muburyo butandukanye bwa infragre.Gukomatanya kwayo gukorera mu mucyo, kwinjirira hasi, kwaguka kwinshi, gutuza ubushyuhe, kurwanya imiti, hamwe na birefringence nkeya bigira uruhare mubikorwa byayo byiza bya infragre.
