Iimpawu ezahlukeneyo zeglasi yeglasi ekhanyayo ye-convex egxile kwilensi
Yintoni uMandisaIlensi yeglasi?
Ziyakhulisa iilensi ezenziwe ngeelensi zeglasi, njengeglasi eluhlaza, iOptical glass lens, K9, njalo njalo.izinto zeglasi ye-optical zizinzile kwaye isalathisi somzimba siphakathi.Ayizukuguga ngokulula kusetyenziso lwexesha elide kwaye umphezulu kulula ukunyanga, kwangaxeshanye, isikhulisa-gilasi sinokuthi sifumane unyango oluchanekileyo oluchanekileyo, olunokufikelela kwiziphumo ezininzi eziphezulu, ukuhanjiswa okuphezulu kokuthelekisa, i-anti infrared kunye ne-anti-infrared. i-ultraviolet, njl.
Iglasi eyayisetyenziswa ekuqaleni ukwenza iilensi ngamaqhuma akwiglasi yefestile okanye iibhotile zewayini.Ubume bufana "nesithsaba", apho igama leglasi yesithsaba okanye isithsaba seglasi leglasi livela.Ngelo xesha, iglasi yayingalingani kwaye igwebu.Ukongeza kwiglasi yesithsaba, kukho olunye uhlobo lweglasi elityebileyo enomxholo ophezulu wokukhokela.Malunga nowe-1790, uPierre Louis junnard, umFrentshi, wafumanisa ukuba isosi yeglasi eshukumayo inokwenza iglasi ibe nokwakheka okufanayo.Ngowe-1884, uErnst Abbe no-Otto Schott beZeiss baseka iSchott glaswerke Ag eJena, eJamani, baza benza iiglasi ezininzi zamehlo kwiminyaka nje embalwa.Phakathi kwabo, ukuveliswa kweglasi yesithsaba se-barium kunye ne-high refractive index yenye yeempumelelo ezibalulekileyo ze-Schott glass factory.
Icandelo:
Iglasi ye-Optical ixutywe kunye ne-oxides ye-silicon ephezulu ecocekileyo, i-boron, i-sodium, i-potassium, i-zinc, i-lead, i-magnesium, i-calcium, i-barium, njl njl ngokwefomula ethile, inyibilika kwiqondo lokushisa eliphezulu kwi-platinum crucible, ixutywe ngokulinganayo kunye ne-ultrasonic wave. ukususa amaqamza;Emva koko pholisa kancinci ixesha elide ukuthintela uxinzelelo lwangaphakathi kwibhloko yeglasi.Ibhloko yeglasi epholileyo kufuneka ilinganiswe ngezixhobo ze-optical ukujonga ukuba ukucoceka, ukungafihli, ukufana, isalathisi se-refractive kunye ne-dispersion index ihlangabezana neenkcukacha.Ibhloko yeglasi evunyiweyo iyafudunyezwa ize yenziwe i-optical lens rough embryo.
Ukuhlelwa:
Iiglasi ezinokwakheka kweekhemikhali ezifanayo kunye neempawu ze-optical nazo zihanjiswa kwiindawo ezikufutshane kumzobo we-abet.I-abettu ye-glass factory ye-Schott inesethi yemigca echanekileyo kunye neengqungquthela, ezahlula i-abettu kwiindawo ezininzi kwaye zihlula i-glass optical;Umzekelo, iglasi yesithsaba i-K5, i-K7 kunye ne-K10 zikwizowuni K, kunye neglasi yelitye lenyengane F2, F4 kunye no-F5 zikwizowuni F. Iimpawu kumagama eglasi: F imele iflint, K ipleyiti yesithsaba, B yeboron, ba yebharium , LA i-lanthanum, i-lead-free kunye ne-P ye-phosphorus.
Kwi-lens yeglasi, i-angle enkulu yokujonga, inkulu umfanekiso, kwaye iyakwazi ukwahlula iinkcukacha zento.Ukusondela kwinto kunokunyusa i-angle yokujonga, kodwa inqunyanyiswa yikhono lokugxila kwiso.Ukusebenzisa iglasi yokukhulisa ukwenza ukuba kufutshane neliso, kwaye ubeke into ngaphakathi kugxininiso lwayo ukwenza umfanekiso othe tye.
Umsebenzi weglasi yokukhulisa kukukhulisa i-engile yokujonga.Ngokwembali, kuthiwa ukusetyenziswa kweglasi yokukhulisa kwacetywa ngugrosstest, ubhishophu waseNgilani ngenkulungwane ye-13.
Ilensi yeglasi iyaxhathisa ngakumbi kunezinye iilensi, kodwa ubunzima bayo bunzima, kwaye isalathiso saso sokuphinda siphinde sibe phezulu: ifilimu eqhelekileyo yi-1.523, ifilimu ecwecwe kakhulu ingaphezulu kwe-1.72, ukuya kuthi ga kwi-2.0.
Eyona mathiriyeli ekrwada yeglasi yelensi yiglasi yokukhanya.Isalathiso saso sokuqhafaza siphezulu kunelensi ye-resin, ngoko ke phantsi kweqondo elifanayo, i-lens yeglasi incinci kune-resin lens.Ilensi yeglasi inokuhanjiswa kokukhanya okulungileyo kunye neempawu zoomatshini kunye neekhemikhali, isalathiso se-refractive esiqhubekayo kunye neempawu ezizinzileyo zomzimba kunye neekhemikhali.I-lens ngaphandle kombala ibizwa ngokuba yi-optical white tray (ifilimu emhlophe), kunye nefilimu epinki kwifilimu enemibala ibizwa ngokuba yi-croxay lens (ifilimu ebomvu).I-Croxay lens inokufunxa imitha ye-ultraviolet kwaye ifunxe ukukhanya okunamandla.
Icwecwe leglasi lineempawu eziphezulu ze-optical, akukho lula ukukrwempa, kwaye linesalathiso esiphezulu se-refractive.Ukuphakama kwesalathisi se-refractive, i-lens encinci.Kodwa iglasi ibuthathaka kwaye izinto eziphathekayo zinzima kakhulu.
Yeyiphi ilensi esetyenziswa kwiglasi yokukhulisa?
Ilensi yeConvex
Iglasi yokukhulisa iglasi yilensi yeconvex esetyenziselwa ukwenza into ibonakale inkulu kakhulu kunokuba injalo.Oku kusebenza xa into ibekwe kumgama ongaphantsi kobude bojoliso.
Ndidinga iglasi yokukhulisa ubungakanani?
Ngokubanzi, isikhulisa-2-3X esibonelela ngebala elikhulu lokujonga singcono kwimisebenzi yokuskena efana nokufunda, ngelixa ibala elincinane elinxulunyaniswa nokwandiswa okuphezulu kunokufaneleka ngakumbi kuhlolo lwezinto ezincinci.
