Prism ke ntho ea optical e fetolang leseli ka li-angles tse itseng ho latela ketsahalo ea eona le li-angles tsa ho tsoa. Li-prism li sebelisoa haholo lits'ebetsong tsa optical ho fetola tsela ea litsela tse bobebe, ho hlahisa li-inversion tsa litšoantšo kapa ho kheloha, le ho nolofalletsa mesebetsi ea ho hlahloba.
Li-prism tse sebelisetsoang ho fetola tsela ea maballo a leseli hangata li ka aroloa ka prism e bonts'ang le e refracting prism.
Li-prism tse bonts'ang li entsoe ka ho sila sebaka se le seng kapa tse 'maloa holim'a khalase ho sebelisa molao-motheo oa ho bonahatsa ka hare le theknoloji ea ho roala. Ponahalo e felletseng ea ka hare e etsahala ha mahlaseli a khanya a tsoang ka har'a prism a fihla holimo ka angle e kholo ho feta ea mahloriso bakeng sa ponahalo eohle ea kahare, 'me mahlaseli ohle a khanya a bonahatsoa ka hare. Haeba khanya eohle ea ka hare ea leseli la ketsahalo e sa khonehe, tšepe e khanyang e kang silevera, aluminium, kapa khauta, e lokela ho behoa holim'a metsi ho fokotsa tahlehelo ea matla a khanya sebakeng se khanyang. Ho phaella moo, e le ho eketsa phetisetso ea prism le ho fokotsa kapa ho felisa leseli le lahlehileng tsamaisong, liphahlo tse khahlanong le ho bonahatsa ka har'a mefuta e itseng ea spectral li behoa holim'a sebaka se kenang le sa ho tsoa sa prism.
Ho na le mefuta e mengata ea li-prism tse bonahatsang ka libopeho tse fapaneng. Ka kakaretso, e ka aroloa ka li-prism tse bonolo (tse kang prism ea lehlakoreng le letona, pentagonal prism, Dove prism), marulelo a marulelo, prism ea pyramid, prism e kopantsoeng, joalo-joalo.
Li-prism tse refracting li ipapisitse le molao-motheo oa refraction ea leseli. E na le libaka tse peli tsa refractive, 'me mola o entsoeng ke mateano a libaka tse peli o bitsoa refractive edge. Karolo e pakeng tsa libaka tse peli tse refracting e bitsoa angle refraction ea prism, e emetsoeng ke α. Karolo e lipakeng tsa lehlaseli le lehlaseli la ketsahalo e bitsoa deviation angle, e emeloang ke δ. Bakeng sa prism e itseng, angle refraction α le refractive index n ke litekanyetso tse tsitsitseng, 'me angle ea ho kheloha δ ea prism ea refractive e fetoha feela ka angle ea ketsahalo I ea lehlaseli la lebone. Ha tsela ea khanya ea leseli e lekana le prism e refracting, boleng bo tlase ba angle ea ho kheloha boa fumanoa, 'me polelo ke:
The optical wedge kapa wedge prism e bitsoa prism e nang le angle e nyane haholo ea refraction. Ka lebaka la sekhutlo se sa tsotelleng sa refraction, ha khanya e etsahala e otlolohile kapa e batla e otlolohile, poleloana ea ho kheloha ha chesele e ka nolofatsoa joalo ka: δ = (n-1) α.
Litšobotsi tsa ho roala:
Ka tloaelo, lifilimi tse bonts'ang tsa aluminium le silevera li sebelisoa holim'a seipone sa prism ho ntlafatsa ponahalo ea khanya. Lifilimi tse khahlano le pono li boetse li khabisitsoe holim'a ketsahalo ena le libaka tsa ho tsoa ho eketsa phetiso ea leseli le ho fokotsa khanya e khelohang lihlopha tse fapaneng tsa UV, VIS, NIR, le SWIR.
Makala a kopo: Li-Prism li fumana lits'ebetso tse ngata ho lisebelisoa tsa dijithale, lipatlisiso tsa mahlale, lisebelisoa tsa bongaka le libaka tse ling. - Thepa ea dijithale: lik'hamera, lithelevishene tse koetsoeng (CCTV), liprojeke, lik'hamera tsa dijithale, lik'hamera tsa dijithale, lilense tsa CCD, le lisebelisoa tse fapaneng tsa mahlo. - Patlisiso ea mahlale: libonela-hōle, li-microscopes, maemo / tse shebaneng le tlhahlobo ea menoana kapa pono ea lithunya; li-converter tsa letsatsi; lisebelisoa tsa ho lekanya tsa mefuta e fapaneng. - Lisebelisoa tsa bongaka: li-cystoscopes / gastroscopes hammoho le lisebelisoa tse fapaneng tsa kalafo ea laser.
Jiujon Optics e fana ka mefuta e mengata ea lihlahisoa tsa prism tse kang li-prism tse lehlakoreng le letona tse entsoeng ka khalase ea H-K9L kapa quartz e kopantsoeng ea UV. Re fana ka pentagon prism, Dove prism, Roof prism, corner-cube prism, UV fused silica corner-cube prism, le wedge prism tse loketseng ultraviolet (UV), light light (VIS), haufi-infrared (NIR) lihlopha tse nepahetseng tse fapaneng. maemo.
Lihlahisoa tsena li koahetsoe joaloka filimi ea aluminium / silevera / khauta e bonahatsang filimi / anti-reflection filimi / nickel-chromium tšireletso / tšireletso ea pente e ntšo.
