Malenzi anozivikanwa nevanhu vazhinji, uye anoita basa guru mukugadzirisa myopia mumagirazi.Malenzi ane akaturikidzana akasiyana, senge green coating, yeblue coating, yebhuruu-yepepuru coating, uye kunyange yeumbozha goridhe coating.Kusakara uye kubvaruka kwemachira ekuputira ndicho chimwe chezvikonzero zvikuru zvekutsiva magirazi emaziso, saka ngatidzidzei zvakawanda nezve machira ekuputira emalenzi.
Kuvandudzwa kwekuvhara lens
Pamberi pekuuya kweresin lenses, magirazi egirazi aiwanzo shandiswa.Mabhenefiti egirazi lenzi akakwira refractive index, high light transmittance, uye kuomarara kwakanyanya, asi zvakare ane zvazvakaipira senge kutatarika, kurema, uye kusachengeteka.
Kugadzirisa zvimhingamupinyi zvemagirazi egirazi, mafekitari akagadzira zvinhu zvakasiyana-siyana zvekutsiva magirazi egirazi, asi hapana akakodzera.Nyaya imwe neimwe ine zvayakanakira nezvayakaipira, uye zvakaoma kuwana chiyero.Izvi zvinoshandawo kune ikozvino resin lenses (resin zvinhu).
Kune ikozvino resin lenses, kupfeka ibasa rinodiwa.Resin zvinhu zvakare zvine akawanda maclass, akadai MR-7, MR-8, CR-39, PC, NK-55-C, uye mamwe akawanda maresin zvinhu, imwe neimwe iine maitiro akasiyana.Kunyangwe iri girazi regirazi kana resin lens, mwenje uchipfuura nepamusoro pelens uso unosangana neakasiyana optical phenomena: kuratidza, refraction, kutora, kuparadzira, uye kutapurirana.
Kupfekedza lens ne-anti-reflective film
Chiedza chisati chasvika pamusoro pechiso chelens, i100% chiedza chesimba, asi kana ichibuda mulenzi uye ichipinda muziso, haisisiri 100% chiedza chesimba.Iyo yakakwirira chikamu chesimba rechiedza, zviri nani kutapurirana kwechiedza, uye kukwira kwemhando yekufungidzira nekugadziriswa.
Kune chaiyo lens zvinhu, kuderedza kutarisisa kurasikirwa inzira yakajairika yekuwedzera kutapurirana kwemwenje.Kuwedzera kuratidzwa kwechiedza, kunoderedza kutapurirana kwelenzi, zvichikonzera kutadza kwekufungidzira kunaka.Nokudaro, kuderedza kufungisisa kwazova dambudziko iro resin lenses inofanira kugadzirisa, uye anti-reflective film (AR firimu) yakashandiswa kune lens (pakutanga, anti-reflective coatings yakashandiswa pane mamwe lenses optical).
Anti-reflective firimu rinoshandisa mutemo wekuvhiringidza kuti uwane hukama pakati pechiedza chekuwedzera kwechiedza chekuvhara lens anti-reflective film layer uye wavelength yechiitiko chechiedza, kukora kwefirimu layer, refractive index yefirimu layer, uye iyo refractive indekisi ye lens substrate, ichibvumira mwenje ichipfuura nepakati yefirimu layer kuti ibvise mumwe nemumwe kunze, ichideredza kurasikirwa kwesimba rechiedza pane lens pamusoro nekuvandudza kunaka kwekufungidzira uye kugadzirisa.
Anti-reflective coatings inowanzo shandisa high-purity metal oxides yakadai setitanium dioxide uye cobalt oxide, iyo inoiswa pamusoro pe lens pamusoro kuburikidza ne evaporation process (vacuum deposition) kuti iwane yakanaka anti-reflective madhara.Anti-reflective coatings anowanzosiya masara, uye mazhinji emafirimu akaturikidzana ari kunyanya mugirinhi ruvara renji.
Mucherechedzo weiyo anti-reflective firimu inogona kudzorwa, semuenzaniso, kubudisa firimu rebhuruu, blue-violet film, violet film, grey film, nezvimwewo.Mhando dzakasiyana dzemafirimu ane mavara ane misiyano mukugadzirwa kwekugadzira.Semuenzaniso, firimu yebhuruu inoreva kuti kuratidzira kwakaderera kunoda kudzorwa, uye kuoma kwekuputira kwakakura kudarika iyo yefirimu yakasvibirira.Nekudaro, mutsauko mukufambiswa kwechiedza pakati pebhuruu negirinhi mafirimu unogona kunge uri pasi pe1%.
Muzvigadzirwa zvemalenzi, mafirimu ebhuruu anowanzo zivikanwa pakati pemalenzi epamusoro.Pamutemo, kufambiswa kwechiedza kwemafirimu ebhuruu kwakakwira kupfuura kwemafirimu egirinhi (ona kuti izvi zviri musimboti) nekuti mwenje musanganiswa wewavelengths akasiyana, uye mawavelength akasiyana ane nzvimbo dzakasiyana dzekufungidzira pane retina.Mumamiriro ezvinhu akajairika, chiedza cheyero-chegirini chinonyatso fananidzwa neretina, uye ruzivo rwekuona rwunopihwa nechiedza chegirinhi rwakakwirisa, saka ziso remunhu rinonzwa nechiedza chegirinhi.
Kupfekedza lens nefirimu yakaoma
Pamusoro pekutapurirana kwechiedza, zvese zviri zviviri resin uye magirazi zvinhu zvine akakosha drawback: ma lens haana kuoma zvakakwana.
Mhinduro ndeyekugadzirisa izvi nekuwedzera yakaoma firimu coating.
Kuomarara kwepamusoro kwemagirazi lenzi kwakakwira zvakanyanya (kazhinji kunosiya mashoma maronda kana achikweshwa nezvinhu zvakajairika), asi izvi handizvo zvakaita resin lenzi.Resin lenses inokwenywa nyore nyore nezvinhu zvakaoma, zvichiratidza kuti haibatike.
Kuti uvandudze kupikisa kupfeka kwema lens, zvakakosha kuwedzera firimu yakaoma yekuvhara kune lens pamusoro.Mabhaisikopo akaomarara anowanzo shandisa maatomu esilicon pakuomesa kurapa, achishandisa mushonga wekuomesa une organic matrix uye inorganic ultrafine particles zvinosanganisira silicon zvinhu.Iyo firimu yakaoma panguva imwe chete ine kuoma uye kuoma (iyo firimu layer iri pamusoro pe lens yakaoma, uye lens substrate haina brittle, kusiyana negirazi rinotsemuka nyore).
Iyo huru yemazuva ano tekinoroji yekuomarara firimu kunyudzwa.Iyo yakaoma firimu yekuputira inenge yakakora, inenge 3-5μm.Kune resin lenses ine yakaoma film coatings, vanogona kuzivikanwa neruzha rwekutapa padesktop uye kupenya kwemavara lens.Malenzi anoburitsa ruzha rwakajeka uye ane mipendero yakapenya akawana kurapwa kwakaoma.
Kupfekedza lens ne-anti-fouling firimu.
Anti-reflective firimu uye yakaoma firimu ndiwo maviri ekutanga machira eresin lenzi parizvino.Kazhinji, firimu rakaoma rinotanga kuputirwa, rinoteverwa ne-anti-reflective film.Nekuda kwezvipimo zvazvino zve anti-reflective firimu zvinhu, pane kupokana pakati pe-anti-reflective uye anti-fouling masimba.Nekuti iyo anti-reflective firimu iri mune porous state, inonyanya kukonzeresa kuumba mavara pamusoro pe lens.
Mhinduro ndeyokuwedzera imwe firimu ye-anti-fouling firimu pamusoro pe-anti-reflective film.Iyo anti-fouling firimu inonyanya kuumbwa ne fluorides, iyo inogona kuvhara iyo porous anti-reflective film layer, kuderedza nzvimbo yekubatana pakati pemvura, mafuta, uye lens, asi isingashandure kushanda kwemaziso kweiyo anti-reflective film.
Nekuwedzera kuri kuita kusiyanisa kwezvido, akawanda uye anoshanda akawanda mabhaisikopo akagadzirwa, senge polarizing firimu, anti-static firimu, yebhuruu mwenje yekudzivirira firimu, anti-fog firimu, uye mamwe anoshanda firimu layer.Iyo yakafanana lens zvinhu, iyo yakafanana lens refractive index, mhando dzakasiyana, uye kunyangwe mukati mechiratidzo chimwe chete, iine zvinhu zvakafanana, akasiyana akatevedzana malenzi ane mutengo wakasiyana, uye machira erenzi chimwe chezvikonzero.Kune misiyano mune tekinoroji uye hutano hwehuputi.
Kune akawanda marudzi ekupfekedzwa kwemafirimu, zvakaoma kumunhu wepakati kuti aone kusiyana.Nekudaro, pane imwe mhando yekupotera iyo mhedzisiro inogona kucherechedzwa zviri nyore: yebhuruu mwenje inovharira lenzi (tekinoroji inowanzoshandiswa mune yakakwirira-yekupedzisira bhuruu inovharira lenzi).
Rakanaka rebhuruu rinovharira lens rinosefa kunze kunokuvadza mwenje weblue muchikamu che380-460nm kuburikidza nechiedza chebhuruu chinovharira firimu layer.Nekudaro, pane misiyano mukuita chaiko pakati pezvigadzirwa kubva kune vakasiyana vagadziri.Zvigadzirwa zvakasiyana-siyana zvinoratidza misiyano muchiedza chebhuruu chinovharira kushanda zvakanaka, ruvara rwepasi, uye kutapurirana kwechiedza, izvo zvinotungamira kumitengo yakasiyana.
Lens coating protection
Lens coatings inonzwa kune yakakwirira tembiricha.Iwo machira eresin lenzi anoiswa gare gare uye iwo ese anogovana kushaya simba kwakafanana: vanonzwa nekupisa kwakanyanya.Kuchengetedza machira erenzi kubva pakuputika kunogona kunyatso kuwedzera hupenyu hwemalenzi.Aya anotevera chaiwo nharaunda anowanzo kukonzeresa kukuvadza kune lens coatings:
