Qhov zoo ntawm Calcium Fluoride - CaF2 lo ntsiab muag thiab qhov rais

Calcium Fluoride (CaF2) tuaj yeem siv rau cov qhov rais kho qhov muag, lo ntsiab muag, prisms thiab qhov khoob hauv Ultraviolet rau thaj tsam Infrared.Nws yog cov khoom siv nyuaj, ua ob zaug nyuaj li Barium Fluoride.Cov khoom siv Calcium Fluoride rau kev siv Infra-red yog zus siv cov tshuaj fluorite uas yog ib txwm muaj, hauv cov khoom loj ntawm tus nqi qis.Chemically npaj raw khoom feem ntau yog siv rau UV daim ntaub ntawv.

Nws muaj qhov ntsuas qis heev uas tso cai rau nws siv yam tsis muaj kev cuam tshuam los tiv thaiv txheej.Calcium Fluoride qhov rais nrog polished nto yog ruaj khov thiab yuav kav ntev ntau xyoo nyob rau hauv ib txwm tej yam kev mob mus txog rau thaum kub nce mus txog 600 ° C thaum nws pib mos.Nyob rau hauv qhuav tej yam kev mob nws muaj siab tshaj plaws kev khiav hauj lwm kub ntawm 800 ° C.Calcium Fluoride qhov rais tuaj yeem siv los ua lub laser siv lead ua lossis hluav taws xob kuaj pom siv lead ua los ntawm doping nws nrog cov ntsiab lus tsis tshua muaj hauv ntiaj teb.Nws yog chemically thiab lub cev ruaj khov siv lead ua nrog cov dej resistant zoo heev, tshuaj resistant thiab kub resistant yam ntxwv.Nws muaj kev nqus tsawg thiab kev sib kis tau zoo xws li Nqus Ultraviolet 125nm rau Infra-red 8 microns.Nws qhov tshwj xeeb optical dispersion txhais tau tias nws tuaj yeem siv los ua lub lens achromatic ua ke nrog lwm cov khoom siv kho qhov muag.

Tag nrho cov khoom no txhawb kom muaj kev siv dav hauv astronomy, kev yees duab, microscopy, HDTV optics thiab cov cuab yeej kho mob laser.Calcium Fluoride qhov rais tuaj yeem tsim los ntawm lub tshuab nqus tsev ultraviolet qib Calcium Fluoride uas feem ntau pom nyob rau hauv cryogenically txias thermal imaging systems.Raws li nws yog lub cev ruaj khov thiab tshuaj lom neeg tsis muaj zog nrog cov hardness zoo dua, nws yog cov khoom siv rau kev siv microlithography thiab laser optics.Achromatic Calcium Fluoride lo ntsiab muag tuaj yeem siv rau hauv ob lub koob yees duab thiab lub tsom iav kom txo tau lub teeb tawg thiab hauv kev lag luam roj thiab roj raws li cov khoom siv hauv kev ntes thiab cov spectrometers.
