Optical Coating

Optical coating ke lera le tšesaane kapa likaroloana tsa lintho tse behiloeng holim'a ntho ea optical, joalo ka lense kapa seipone, e fetolang tsela eo karolo ea optical e bonahatsang le ho fetisa leseli ka eona.Mofuta o mong oa ho roala optical coating ke anti-reflective coating, e fokotsang litšoantšo tse sa batleheng tse tsoang holimo, tse sebelisoang hangata likhalaseng tsa mahlo le lilense tsa k'hamera.Mofuta o mong ke seaparo se khanyang haholo, se ka sebelisoang ho hlahisa liipone tse bontšang ho feta 99.99% ea leseli.Liaparo tse rarahaneng tsa optical tse bonts'ang ponahalo e phahameng ho maqhubu a itseng a maqhubu le li-antireflection libakeng tse telele li lumella tlhahiso ea li-filters tsa dichroic thin-film.

Liaparo tse bonolo ka ho fetisisa tsa optical ke likarolo tse tšesaane tsa tšepe, tse kang aluminium, tse behiloeng holim'a karoloana ea khalase ho etsa bokaholimo ba khalase, mokhoa o bitsoang silvering.Tšepe e sebelisitsoeng e etsa qeto ea hore na seipone se na le thepa e khanyang;aluminium ke seaparo se theko e tlaase ka ho fetisisa le se tloaelehileng ka ho fetisisa, se hlahisang hoo e ka bang 88% -92% ponts'ong e bonahalang.E theko e boima haholo ke silevera, e nang le 95% -99% e bonahatsang esita le ka har'a infrared e hōle, empa e fokotsehile ho bonahatsa (<90%) libakeng tse putsoa le ultraviolet spectral.E theko e boima ka ho fetisisa ke khauta, e tletseng infrared.E fana ka ponahatso e ntle haholo (98% -99%), empa ponahalo e lekanyelitsoeng ho wavelengths e ka tlase ho 550 nm, e hlahisang 'mala oa khauta o ikhethang.

Ka ho laola botenya le botenya ba ho roala tšepe, ho bonahatsa maikutlo ho ka fokotsoa 'me phetisetso ea holim'a metsi e eketseha, e leng se hlahisang seipone sa halofo ea silevera.Ka linako tse ling tsena li sebelisoa e le "liipone tsa tsela e le 'ngoe".

Mofuta o mong o moholo oa ho roala optical ke seaparo sa dielectric (ke hore, tšebeliso ea thepa e nang le li-indices tse fapaneng tsa refractive e le substrate).Li na le likarolo tse tšesaane tsa lisebelisoa, joalo ka magnesium fluoride, calcium fluoride, le li-oxide tse fapaneng tsa tšepe, tse kentsoeng holim'a li-optical substrates.Ka ho khetha ka hloko sebopeho se nepahetseng, botenya le palo ea likarolo tsena, ho bonahatsa le ho fetisa ha seaparo ho ka hlophisoa ho hlahisa hoo e batlang e le thepa leha e le efe e lakatsehang.Coefficient e bonts'ang ea bokaholimo e ka fokotsoa ka tlase ho 0.2%, e leng se hlahisang sekoaelo sa anti-reflective (AR).Ka lehlakoreng le leng, ka liaparo tse phahameng-reflection (HR), ponahalo e ka eketsoa ho feta 99.99%.Boemo ba ho bonahatsa maikutlo bo ka boela ba fetoloa ho boleng bo itseng, ka mohlala, ho hlahisa seipone se bonahatsang 90% ka mekhahlelo e itseng ea wavelength le ho fetisetsa 10% ea leseli le oelang ho eona.Liipone tse joalo hangata li sebelisoa e le li-couplers tse tsoang ho li-splitters tsa beam le lasers.Ntle le moo, ho roala ho ka etsoa e le hore seipone se bonahatse feela sehlopha se moqotetsane sa wavelengths, ho theha filthara ea optical.

Ho feto-fetoha ha liphahlo tsa dielectric ho entse hore ho sebelisoe lisebelisoa tse ngata tsa saense tsa optical tse kang lasers, optical microscopes, refractor telescope, le interferometer, hammoho le lisebelisoa tsa bareki tse kang libonela-hōle, likhalase tsa mahlo le lilense tsa lifoto.

Ka linako tse ling likarolo tsa dielectric li sebelisoa holim'a lifilimi tsa tšepe ho fana ka lera le sireletsang (joaloka silicon dioxide holim'a aluminium), kapa ho eketsa ponahalo ea filimi ea tšepe.Metsoako ea tšepe le ea dielectric e boetse e sebelisoa ho etsa liaparo tse tsoetseng pele tse ke keng tsa hlahisoa ka tsela e 'ngoe.Mohlala ke seo ho thoeng ke "seipone se phethahetseng", se bonts'ang ponahalo e phahameng (empa e sa phethahala) e nang le kutlo e tlase e sa tloaelehang ho bolelele ba maqhubu, angle, le polarization.
