Masimong a nepahetseng haholo a kang optoelectronics, theknoloji ea ponts'o, le lisebelisoa tsa optical, lentsoe "filimi e tšesaane ea optical" le hlaha khafetsa. Likoahelo tsena li ama ka ho toba matšoao a bohlokoa a ts'ebetso joalo ka phetisetso, ho bonahatsa, le ho hlahisa mebala, 'me qetellong li bopa boiphihlelo ba pono le tlhahiso e sebetsang ea sehlahisoa sa ho qetela. Empa hantle-ntle lifilimi tse tšesaane tsa optical ke eng, hona li finyella ho fetoloa ho nepahetseng ha leseli joang ka mahlale a tsoetseng pele a ho roala? Sengoloa sena se fana ka kakaretso ea tekheniki.
Lifilimi tse Nyenyane tsa Optical ke Eng?
Lifilimi tse tšesaane tsa mahlo li bua ka liphahlo tse sebetsang tse nang le botenya bo tlohang ho li-nanometer ho isa ho li-micrometer, tse atisang ho beoa holim'a khalase, polasetiki, kapa li-substrate tsa tšepe tse sebelisang mahlale a ho koahela ka vacuum joalo ka mouoane oa mocheso, ho sputtering ha magnetron, kapa ho beoa ha mahlaseli a elektrone. Lifilimi tsena li ka ba le lera le le leng kapa mekhahlelo e mengata e kopaneng, e 'ngoe le e 'ngoe e na le li-indices le botenya bo fapaneng ba refractive, tse entsoeng ho fihlela litlamorao tse itseng tsa mahlo.
Melao-motheo ea Motheo: Tšitiso le ho Fokotsa Khatello
Mokhoa o ka sehloohong o ka morao ho lifilimi tse tšesaane tsa optical ke tšitiso ea optical. Ha leseli le kopana le bokaholimo ba filimi e tšesaane, lea bonahatsoa ka karolo 'me lea refracted sebakeng se seng le se seng sa sebopeho. Ka lebaka la botenya ba filimi bo laoloang le li-index tse fapaneng tsa refractive pakeng tsa mekhahlelo, mahlaseli a bonahatsoang a ka kena-kenana ka mokhoa o hahang kapa ka mokhoa o senyang, ho latela phapang ea bona ea mekhahlelo.
Ka mohlala:
Ha botenya ba filimi bo entsoe ka tsela eo maqhubu a bonaletsang a ka qhalanang, ho fihlellwa ditlamorao tse thibelang ho bonaletsa—tse sebediswang hangata dilenseng kapa khalaseng ya sekoahelo sa photovoltaic.
Ka lehlakoreng le leng, ha maqhubu a bonahatswang a le mokgahlelong, aa matlafatsana, a hlahisa ho filthara e phahameng ya ho bonahatswa kapa ho kgetha bolelele ba leqhubu—jwalo ka ha ho bonwa ho di-splitter tsa mahlasedi, diiponeng tsa laser, kapa difilthara tsa optical.
Phetoho ena ea bolelele ba tsela ea optical e bohareng ba moralo oa filimi e tšesaane, moo botenya hangata e leng kotara ea bolelele ba leqhubu la maqhubu (λ/4) kapa li-multiples tsa eona, e leng se nolofalletsang taolo e nepahetseng holim'a lihlopha tse itseng tsa spectral.
Mefuta e Tloaelehileng ea Liaparo tsa Optical
Liaparo tse sa Bonahaleng (AR Coatings): Thibela ho bonahatsoa ha bokaholimo le ho ntlafatsa phetiso. Li sebelisoa haholo lilenseng tsa khalase ea mahlo, li-optics tsa khamera le liphanele tsa ho ama.
Liaparo tse Bonaletsang ka Bophahamo (Liaparo tsa HR): Eketsa khanya ea khanya maqhubung a lebisitsoeng, a sebelisoang liiponeng tsa laser, mabone a sethaleng le mabone a nepahetseng.
Liaparo tsa Sefe ea Optical: Ka khetho fetisa kapa ho thibela mefuta e itseng ea bolelele ba maqhubu. Li fumanoa li-sensor, lisebelisoa tsa optical le lisebelisoa tsa puisano.
Lifilimi tse Arohanyang/tse Arohanyang Mahlasedi: Arola lesedi ka boemo ba bolelele ba leqhubu kapa ba polarization, le sebediswang dipontshong, diprojektara, le dipontshong tsa hlooho ya koloi (HUDs).
Moralo le Tlhahiso ea Lifilimi tse Nyenyane tsa Optical
Lifilimi tse tšesaane tsa optical tse sebetsang hantle ha li hloke feela khetho e nepahetseng ea thepa empa hape li hloka moralo o rarahaneng oa lera le taolo ea ts'ebetso. Mekhoa ea hona joale ea ho beha lintho e kenyelletsa:
Mouoane oa Thermal
Mouoane oa Mahlaseli a Elektrone (E-Beam)
Ho phunya ha Magnetron
Ho Hlahisa ka Thuso ea Ion (IAD)
Mekhoa ena e dumella ho nepahala ha botenya ba nanometer mme e netefatsa thepa e ts'oanang ya optical ho pholletsa le di-substrate tsa sebaka se seholo.
Ha e le hantle, lifilimi tse tšesaane tsa optical li sebetsa ka ho fetola phatlalatso ea leseli ka tšitiso, ho nolofalletsa ntlafatso, ho fokotsa khanya, ho sefa, kapa taolo ea polarization. Liaparo tsena li kopanya optics ea 'mele, saense ea thepa, le ho kenngoa ha vacuum ka nepo theknolojing e le 'ngoe e kopaneng, li bapala karolo ea bohlokoa indastering ea sejoale-joale ea photonic le ea maemo a holimo. Ha tlhoko e ntse e hola bakeng sa litsamaiso tsa optical tse sebetsang hantle, tse lahleheloang ke khanya e tlase, le tse nyane, boqapi bo tsoelang pele theknolojing ea lifilimi tse tšesaane bo tla tsoela pele ho khanna tsoelo-pele ea indasteri.
