Sefe ea optical ke eng?

Ho na le mefuta e meraro ea li-filter tsa optical: li-shortpass filter, li-longpass le li-bandpass. Filter ea shortpass e lumella li-wavelength tse khuts'oane ho feta wavelength e khaotsoeng ho feta, ha e ntse e thibela bolelele ba wavelength. Ka lehlakoreng le leng, sefahleho se selelele se fetisetsa bolelele ba bolelele ho feta bokahare ba sehiloeng ha se ntse se thibela bolelele bo bokhuts'oane. Sefaele sa bandpass ke sefaele se lumellang mofuta o itseng, kapa "band", ea bolelele ba bokahare ho feta, empa e thibela maqhubu ohle a bokahohle ho potoloha sehlopha. Sefe ea monochromatic ke boemo bo fetelletseng ba sefahleho sa bandpass, se fetisang feela marang-rang a fokolang haholo a bokahohle.

Filter ea Optical e fetisa karolo e le 'ngoe ea optical, ha e ntse e hana likarolo tse ling. E sebelisoa hangata ho microscopy, spectroscopy, tlhahlobo ea lik'hemik'hale le pono ea mochini.
Lisebelisoa tsa Optical ke lisebelisoa tse sa sebetseng tse lumellang phetiso ea bokahohle bo itseng kapa sete ea boka ba bokahare ba leseli. Ho na le lihlopha tse peli tsa li-filters tse nang le mekhoa e fapaneng ea ts'ebetso: li-filters tse kenang le li-filters.
Metlhotlo e monyang e na le lintho tse ikopantseng tse etsang lintho tse fapaneng tse amohelang mahlaseli a itseng a khanya, ka hona e lumella maqhubu a sefahleho a lakatsehang hore a fete. Kaha li monya matla a khanya, mocheso oa li-filters tsena oa eketseha nakong ea tšebetso. Ke li-filtha tse bonolo 'me li ka eketsoa ho li-plastiki ho etsa lifilitara tse theko e tlase ho feta tsa baetsi ba bona ba likhalase. Ts'ebetso ea li-filtha tsena ha ea itšetleha ka lehlakore la khanya ea ketsahalo empa le ho thepa ea thepa e etsang lihlotlo. Ka lebaka leo, ke lifilimi tse ntle tseo u ka li sebelisang ha leseli le bonahatsang la bokaholimo bo sa batleheng le ka baka lerata lets'oao la Optical.
Metlhotlo ea Dichroic e rarahane haholoanyane ts'ebetsong ea eona. Li na le letoto la ho roala mahlo ka botenya bo nepahetseng bo etselitsoeng ho bonts'a bokahohle bo sa batleheng le ho fetisa bolelele ba bokahohle bo batlang. Sena se fihlelleha ka ho baka hore bolelele ba leqhubu bo batloang bo kena-kenane ka mokhoa o hahang lehlakoreng la phetisetso ea sefahla, ha maqhubu a mang a kenella ka mokhoa o hahang ka lehlakoreng la ponts'o ea sefahla.
