Broadband AR Coated Achromatic Lenses
Tlhaloso ea Sehlahisoa
Lilense tsa Achromatic ke mefuta ea lilense tse etselitsoeng ho fokotsa chromatic aberration, e leng bothata bo tloaelehileng ba pono bo etsang hore mebala e hlahe ka tsela e fapaneng ha e feta lense. Lilense tsena li sebelisa motsoako oa lisebelisuoa tse peli kapa ho feta tsa optical tse nang le li-indices tse fapaneng tsa refractive ho tsepamisa maqhubu a fapaneng a maqhubu a khanya sebakeng se le seng, e leng se etsang hore leseli le lesoeu le shebane haholo. Lilense tsa Achromatic li sebelisoa haholo lits'ebetsong tse fapaneng tse kang ho nka lifoto, microscope, libonela-hōle le libonela-hōle. Li thusa ho ntlafatsa boleng ba setšoantšo ka ho fokotsa likhahla tsa mebala le ho hlahisa litšoantšo tse nepahetseng le tse bohale. Li boetse li sebelisoa hangata lits'ebetsong tsa laser le lisebelisoa tsa optical tse hlokang ho nepahala le ho hlaka haholo joalo ka lisebelisoa tsa bongaka, li-spectrometer le lisebelisoa tsa bolepi ba linaleli.
Broadband AR Coated Achromatic Lenses ke lilense tsa optical tse fanang ka bokhoni ba ho nahana ka boleng bo holimo holim'a mefuta e mengata e fapaneng ea maqhubu a khanya. Lilense tsena li loketse lits'ebetso tse fapaneng tse kenyelletsang lipatlisiso tsa mahlale, litšoantšo tsa bongaka le theknoloji ea sefofane.
Joale hantle-ntle lense ea Broadband AR e tlotsitsoeng ka achromatic ke eng? Ka bokhutšoanyane, li etselitsoe ho rarolla mathata a chromatic aberration le tahlehelo ea leseli e ka hlahang ha leseli le khelosoa ka lilense tsa setso. Chromatic aberration ke ho sothofala ha setšoantšo ho bakoang ke ho sitoa ha lense ho tsepamisa mebala eohle ea khanya sebakeng se le seng. Lilense tsa Achromatic li rarolla bothata bona ka ho sebelisa mefuta e 'meli e fapaneng ea likhalase (hangata khalase ea moqhaka le khalase ea lejoe le thata) ho etsa lense e le' ngoe e ka lebisang mebala eohle ea khanya ka nako e le 'ngoe, e hlahisang setšoantšo se hlakileng le se bohale.
Empa lilense tsa achromatic hangata li na le tahlehelo ea leseli ka lebaka la likhakanyo tse tsoang holim'a lense. Mona ke moo li-coatings tsa Broadband AR li kenang teng. Ho roala ha AR (anti-reflective) ke lesela le lesesaane la thepa e sebelisoang holim'a lense e thusang ho fokotsa ho bonahatsa le ho eketsa boholo ba khanya e fetisoang ka lense. Maqhubu a Broadband AR a ntlafala holim'a liphahlo tse tloaelehileng tsa AR ka ho lumella phetiso e betere ea khanya ho feta mefuta e mengata e pharalletseng ea maqhubu.
Hammoho, lense ea achromatic le coating ea Broadband AR e fana ka sistimi e matla ea mahlo e ka ntlafatsang ts'ebetso lits'ebetsong tse fapaneng. Li sebelisoa nthong e 'ngoe le e 'ngoe ho tloha ho li-spectrometer ho isa ho libonela-hōle esita le lisebelisoa tsa laser. Ka lebaka la bokhoni ba tsona ba ho fetisa karolo e phahameng ea khanya ho pholletsa le mabala a pharaletseng, lilense tsena li fana ka litšoantšo tse bohale, tsa boleng bo phahameng libakeng tse fapaneng le lits'ebetsong.
Broadband AR-coated achromatic lenses ke mokhoa o matla oa optical o ka fanang ka litšoantšo tsa boleng bo phahameng holim'a mefuta e mengata ea maqhubu a khanya. Ha thekenoloji e ntse e tsoela pele ho iphetola, ha ho pelaelo hore lilense tsena li tla phetha karolo ea bohlokoa haholo lipatlisisong tsa saense, litšoantšo tsa bongaka le lits'ebetsong tse ling tse ngata.
