Imininingwane ehlukahlukene ye-optical glass flat convex focusing lens

Yini UkukhulisaIlensi yengilazi?

Amalensi akhulisayo enziwe ngamalensi engilazi, njengeGreen glass, Optical glass lens, K9, njalo njalo.impahla yengilazi ebonakalayo izinzile futhi inkomba ebonakalayo iphakathi.Ngeke iguge kalula kangaka ekusetshenzisweni kwesikhathi eside futhi kulula ukuphatha indawo engaphezulu, ngasikhathi sinye, isikhulisi sengilazi singaphinda sithole ukwelashwa okunembe kakhudlwana kwe-optical coating, okungafinyelela imiphumela eminingi ephakeme, ukudluliswa kokuqhathanisa okuphezulu, i-anti infrared kanye ne-anti-infrared. i-ultraviolet, njll.

Ingilazi ekuqaleni eyayisetshenziswa ukwenza amalensi amaqhuqhuva engilazini yefasitela evamile noma amabhodlela ewayini.Ukuma kufana "nomqhele", okuvela kuyo igama lengilazi yomqhele noma ingilazi yepuleti yomqhele.Ngaleso sikhathi, ingilazi yayingalingani futhi inegwebu.Ngaphezu kwengilazi yomqhele, kunolunye uhlobo lwengilazi ye-flint enokuqukethwe okuphezulu komthofu.Cishe ngo-1790, uPierre Louis junnard, umFulentshi, wathola ukuthi isoso yengilazi enyakazayo ingenza ingilazi ibe nokuthungwa okufanayo.Ngo-1884, u-Ernst Abbe no-Otto Schott beZeiss basungula i-Schott glaswerke Ag eJena, eJalimane, futhi benza inqwaba yezingilazi ezibonakalayo phakathi neminyaka embalwa.Phakathi kwazo, ukusungulwa kwengilazi yomqhele we-barium ene-high refractive index ingenye yezimpumelelo ezibalulekile ze-Schott glass factory.

Isakhi:

Ingilazi ye-Optical ixubene nama-oxide e-silicon ehlanzekile, i-boron, i-sodium, i-potassium, i-zinc, i-lead, i-magnesium, i-calcium, i-barium, njll ngokusho kwefomula ethile, encibilikisiwe ekushiseni okuphezulu ku-crucible ye-platinum, inyakaziswa ngokulinganayo ngegagasi le-ultrasonic. ukususa ama-bubbles;Bese upholisa kancane isikhathi eside ukuze ugweme ukucindezeleka kwangaphakathi ku-block glass.Ibhulokhi yengilazi epholile kufanele ikalwe ngamathuluzi okubona ukuze kubhekwe ukuthi ubumsulwa, ukungafihli, ukufana, inkomba ye-refractive kanye nenkomba yokuhlakazwa kuyahlangabezana yini nezicaciso.Ibhulokhi yengilazi efanelekile iyashisiswa futhi ihlanganiswe ukwenza i-optical lens rough embryo.

Ukuhlukaniswa:

Izibuko ezinokwakheka kwamakhemikhali okufanayo nezici zokubona nazo zisakazwa ezindaweni eziseduze kumdwebo we-abet.I-abettu yefekthri yengilazi ye-Schott inesethi yemigqa eqondile namajika, ehlukanisa i-abettu ezindaweni eziningi futhi ihlukanise ingilazi ebonakalayo;Isibonelo, ingilazi yomqhele i-K5, i-K7 ne-K10 iku-zone K, futhi ingilazi ye-Flint F2, F4 kanye no-F5 ikuzoni F. Izimpawu emagameni engilazi: F imele iflint, K yepuleti lomqhele, B ye-boron, ba ye-barium , i-LA nge-lanthanum, n ye-lead-free kanye ne-P ye-phosphorus.
Kulensi yengilazi, i-engeli yokubuka ibe nkulu, isithombe sikhulu, nokukwazi ukuhlukanisa imininingwane yento.Ukusondela entweni kungakhuphula i-engeli yokubuka, kodwa kunqunyelwe ikhono lokugxila leso.Ukusebenzisa ingilazi yokukhulisa ukuzenza ibe seduze neso, futhi ubeke into phakathi kokugxila kwayo ukuze kwakhe isithombe esiqondile esibonakalayo.
Umsebenzi wengilazi yokukhulisa ukukhulisa i-engeli yokubuka.Ngokomlando, kuthiwa ukusetshenziswa kwengilazi yokukhulisa izingane kwahlongozwa ugrosstest, umbhishobhi waseNgilandi ekhulwini le-13.

Ilensi yengilazi imelana nokuklwebheka kunamanye amalensi, kodwa isisindo sayo sinzima kakhulu, futhi inkomba yayo ye-refractive iphakeme uma kuqhathaniswa: ifilimu evamile ingu-1.523, ifilimu encane kakhulu ingaphezu kuka-1.72, ifika ku-2.0.

Impahla eyinhloko ye-glass lens ingilazi ye-optical.Inkomba yayo ye-refractive iphakeme kuneye-resin lens, ngakho-ke ngaphansi kwezinga elifanayo, i-glass lens incane kune-resin lens.Ilensi yengilazi inokudlulisa ukukhanya okuhle kanye nezakhiwo zemishini nezamakhemikhali, inkomba ye-refractive engashintshi kanye nezakhiwo ezinzile ngokomzimba namakhemikhali.I-lens engenambala ibizwa ngokuthi i-optical white tray (ifilimu emhlophe), futhi ifilimu ebomvana efilimini enemibala ibizwa ngokuthi i-croxay lens (ifilimu ebomvu).I-Croxay lens ingakwazi ukumunca imisebe ye-ultraviolet futhi imunce kancane ukukhanya okuqinile.

Ishidi lengilazi linezinto ezibonakalayo eziphakeme kakhulu, akulula ukuzinwaya, futhi linenkomba ye-refractive ephezulu.Uma iphezulu inkomba ye-refractive, i-lens iba mncane.Kodwa ingilazi intekenteke futhi impahla isinda kakhulu.

Iyiphi ilensi esetshenziswa ekukhuliseni ingilazi?

I-convex lens
Ingilazi yokukhulisa i-lens eyi-convex esetshenziselwa ukwenza into ibonakale inkulu kakhulu kunalokho eyikho ngempela.Lokhu kusebenza uma into ibekwe ebangeni elingaphansi kobude bokugxila.

Ngidinga ingilazi yokukhulisa usayizi onjani?

Ngokuvamile, isikhulisi esingu-2-3X esinikeza inkambu enkulu yokubuka singcono emisebenzini yokuskena efana nokufunda, kuyilapho inkambu encane ehlotshaniswa nokukhuliswa okuphezulu izofaneleka kakhulu ekuhlolweni kwezinto ezincane.
