Muminda ine kunyatsojeka kwakadai se optoelectronics, display technology, uye optical instrumentation, izwi rekuti "optical thin film" rinowanzo buda. Mapendi aya anokanganisa zvakananga zviratidzo zvikuru zvekushanda zvakaita se transmittance, reflection, uye color rendering, uye pakupedzisira anoumba ruzivo rwekuona uye mashandiro echigadzirwa chekupedzisira. Asi chii chinonzi optical thin films chaizvo, uye anowana sei kugadziriswa kwechiedza chakarurama kuburikidza ne tekinoroji yepamusoro ye coating? Chinyorwa chino chinopa ongororo yehunyanzvi.
Chii Chinonzi Mafirimu Matete Emaziso?
Mafirimu matete eOptical anoreva machira anoshanda ane ukobvu hunotangira pa nanometers kusvika kuma micrometers, anowanzoiswa pagirazi, purasitiki, kana substrates dzesimbi achishandisa matekinoroji ekuputira vacuum akadai se thermal evaporation, magnetron sputtering, kana electron beam deposition. Mafirimu aya anogona kunge aine layer imwe chete kana layer dzakawanda dzakaunganidzwa, imwe neimwe ine refractive indices dzakasiyana uye ukobvu, dzakagadzirirwa kuwana mhedzisiro chaiyo ye optical.
Nheyo Dzekutanga: Kupindira uye Kuramba
Chinhu chikuru chiri shure kwemafirimu matete e optical i optical interference. Kana chiedza chikasangana nepamusoro pefirimu rakatetepa, chinoratidzwa zvishoma uye chinodzorwa pane imwe neimwe interface. Nekuda kweukobvu hwefirimu hwakadzorwa uye kusiyana kwezviratidzo zve refractive pakati pezvikamu, mwenje inoratidzwa inogona kukanganisa kuvaka kana kuparadza, zvichienderana nekusiyana kwechikamu chavo.
Semuyenzaniso:
Kana ukobvu hwefirimu hwakagadzirwa zvekuti mafungu anoratidzwa anodzima, mhedzisiro yekusapenya inoitika—inowanzo shandiswa mumalenzi kana magirazi ekuvhara e photovoltaic.
Kusiyana neizvi, kana mafungu anoratidzwa ari muchikamu, anosimbisana, zvichigadzira kupenya kwakanyanya kana kusvina kwehurefu hwemafungu—sezvinoonekwa muma "beam splitters", magirazi e-laser, kana ma "optical filters".
Kuchinja uku kwehurefu hwenzira ye optical kuri pakati pekugadzirwa kwefirimu diki, uko ukobvu hunowanzova chikamu chimwe muzvina chehurefu hwewavelength (λ/4) kana huwandu hwayo, zvichigonesa kutonga kwakanyatsojeka pamusoro pemabhendi chaiwo espectral.
Mhando Dzakajairika dzeOptical Coatings
Mapendi Anodzivirira Kupenya (AR Coatings): Anodzivirira kupenya kwepamusoro uye anowedzera kufambiswa kwemhepo. Anoshandiswa zvakanyanya pamalenzi egirazi, makamera, uye mapaneru ekubata.
Mapendi Anoratidza Ruvara Rwakanyanya (HR Coatings): Wedzera kuratidzwa kwechiedza pahurefu hwemafungu akananga, anoshandiswa mumagirazi elaser, mwenje wepadanho, uye magirazi ekuona akajeka.
Mapeti eOptical Filter: Anotumira kana kuvharira huwandu hwewavelength hwakatarwa. Anowanikwa mumasensa, zvishandiso zveoptical, uye zvishandiso zvefoni.
Mafirimu Anoparadzanisa/Anoparadzanisa Mwenje: Anoparadzanisa chiedza nehukuru hwewavelength kana polarization, inoshandiswa muzviratidziro, mapurojekita, uye mahudhi emotokari ane musoro (HUDs).
Kugadzira uye Kugadzira Mafirimu Matete Emaziso
Mafirimu matete e optical anoshanda zvakanaka haadi chete kusarudzwa kwezvinhu nemazvo asiwo dhizaini ye layer uye kudzora maitiro. Matekinoroji ekuisa zvinhu anowanikwa pari zvino anosanganisira:
Kubuda kwemvura mumhepo
Kubuda Kwemaerekitironi (E-Beam)
Kusvuta kweMagnetron
Kubviswa kweIon-Assisted (IAD)
Maitiro aya anobvumira kurongeka kweukobvu hwe nanometer uye anovimbisa hunhu hwakafanana hwe optical munzvimbo dzakakura.
Muchidimbu, mafirimu matete e optical anoshanda nekuchinja kupararira kwechiedza kuburikidza nekupindira, zvichiita kuti kuwedzerwa, kuderedzwa, kusefa, kana kudzora polarization. Mapendi aya anobatanidza physical optics, material science, uye precision vacuum deposition mune imwe tekinoroji yakabatana, zvichiita basa guru muindasitiri yemazuva ano ye photonic uye yepamusoro-soro. Sezvo kudiwa kuri kukura kwemasisitimu e optical anoshanda zvakanyanya, asina kurasikirwa zvakanyanya, uye akakwana, kuvandudzwa kuri kuenderera mberi mumatekinoroji e thin-film kucharamba kuchikurudzira kufambira mberi kwemaindasitiri.
