CaF2 Substrate Tlhaloso
Karolo e nyenyane ea CaF2 e bua ka thepa ea substrate e entsoeng ka likristale tsa calcium fluoride (CaF2).Ke thepa e bonaletsang e nang le litšobotsi tse ntle haholo tsa optical, joalo ka phetisetso e phahameng libakeng tsa ultraviolet (UV) le infrared (IR).Li-substrates tsa CaF2 li sebelisoa hangata lits'ebetsong tse fapaneng, ho kenyeletsoa lisebelisoa tsa optical, spectroscopic, fluorescent, le laser.Ba fana ka sethala se tsitsitseng le se sa sebetseng bakeng sa khōlo e tšesaane ea filimi, ho behoa ha ho roala, le ho etsoa ha lisebelisoa tsa optical.Ponaletso e phahameng le index e tlase ea refractive ea CaF2 e etsa hore e tšoanelehe bakeng sa tšebeliso ea likarolo tsa optical tse phahameng haholo tse kang lilense, lifensetere, liprism le li-splitters tsa beam.Ntle le moo, li-substrates tsa CaF2 li na le botsitso bo botle ba mocheso le mochini, li li etsa tse loketseng tikoloho e thata le lisebelisoa tsa laser tse matla a phahameng.Molemo o mong oa karoloana ea CaF2 ke index ea eona e tlase ea refractive.Lenane le tlase la refraction le thusa ho fokotsa tahlehelo ea ho bonahatsa le litlamorao tse sa batleheng tsa optical, ka tsela eo, e ntlafatsa ts'ebetso ea optical le karo-karolelano ea lerata la optics le sistimi.
The substrate ea CaF2 e boetse e na le botsitso bo botle ba mocheso le mochini.Li khona ho mamella mocheso o phahameng mme li bonts'a khanyetso e ntle ea mocheso oa mocheso.Mehaho ena e etsa hore li-substrates tsa CaF2 li tšoanelehe bakeng sa ho sebelisoa libakeng tse boima, joalo ka lisebelisoa tse phahameng tsa laser, moo ho qhala mocheso le ho tšoarella ho leng bohlokoa.
Boiketlo ba lik'hemik'hale ba CaF2 bo boetse bo e fa monyetla.E hanyetsana le mefuta e mengata ea lik'hemik'hale le li-acids, ho bonolo ho sebetsana le ho lumellana le mefuta e sa tšoaneng ea lisebelisoa le mekhoa ea tlhahiso.
Ka kakaretso, motsoako oa thepa e ntle ea optical, botsitso ba mocheso / mochini, le ho se sebetse ha lik'hemik'hale ho etsa hore likaroloana tsa CaF2 li be tse loketseng lits'ebetso tse hlokang li-optics tsa boleng bo holimo le tse tšepahalang.
