Chizvarwa chekare chevanachiremba vemaziso vaiwanzobvunza kana vaine girazi kana makristasi lenzi, uye vakanyomba resin lenzi dzatinowanzo kupfeka nhasi.Nekuti pavakatanga kusangana neresin lenses, tekinoroji yekupfekedza resin lenzi haina kugadzirwa zvakakwana, uye pakanga paine zvinoipira senge kusapfeka-kusapfeka uye nyore kusiya mavara.Mukuwedzera, vazhinji vanogadzira uye vatengesi vane backlog yegirazi lenses inoda kutengeswa, saka zvikanganiso zve resin lenses zvakawedzeredzwa kwenguva yakati.
Magirazi egirazi ane zvakanakira kupfeka kuramba uye yakakwirira refractive index.Asi huremu hwayo uye kusasimba kwayo kwakaita kuti itsiviwa neresin lenzi.Nekufambira mberi kwesainzi uye tekinoroji, tekinoroji yekubikira yakagadziridzwa neindasitiri yekugadzira lens yakagadzirisa matambudziko mazhinji pakutanga kwekugadzirwa kweresin lenzi.Ichi chinyorwa chinokupa sumo pfupi yekupfekedzwa kwemalensi ekuona, kuitira kuti iwe ugone kunyatsonzwisisa machira emalenzi aunopfeka uye nhoroondo yekukura kwawo.
Isu tinowanzo kuve nemhando nhatu dzemachira pamalenzi, anoti, kupfeka-inodzivirira coating, anti-reflection coating, uye anti-fouling coating.Zvikamu zvekupfeka zvakasiyana zvinoshandisa mitemo yakasiyana.Isu tinowanzo ziva kuti ruvara rwemashure eese maresin lenzi uye magirazi lenzi haana ruvara, uye iwo asina kusimba mavara pamalenzi edu akaunzwa neaya akaturikidzana.
Firimu inodzivirira kupfeka
Kuenzaniswa negirazi lenzi (chikamu chikuru chegirazi silicon dioxide, inova inorganic material), pamusoro pemagirazi lenzi akagadzirwa neorganic zvinhu zviri nyore kupfeka.Kune marudzi maviri ekukwenya pamusoro pemagirazi ekuona anogona kucherechedzwa kuburikidza nekuona maikorosikopu.Imwe inogadzirwa nejecha duku nematombo.Kunyangwe zvigwere zvacho zvisina kudzika uye zvidiki, mupfeki haabatike nyore, asi kana zvikwambo zvakadaro zvikaungana kusvika pamwero wakati, chiitiko chekuparadzira chiedza chinokonzerwa nekukwenya kuchakanganisa zvakanyanya kuona kweanopfeka.Kune zvakare kukwenya kukuru kunokonzerwa nematombo makuru kana zvimwe zvinhu zvakaomarara.Rudzi urwu rwekukwenya rwakadzika uye periphery yacho ine rough.Kana kukwenya kuri pakati pe lens, kunokanganisa kuona kweanopfeka.Naizvozvo, iyo firimu inodzivirira kupfeka yakavapo.
Iyo firimu inodzivirira kupfeka yakavewo nezvizvarwa zvakati zvebudiriro.Pakutanga, yakatanga kuma1970.Panguva iyoyo, zvaitendwa kuti girazi rakanga risingapfeki nekuda kwekuoma kwaro, saka kuitira kuti resin lens ive nekupfeka kwakafanana, nzira yekuputira vacuum yakashandiswa., chidimbu che quartz zvinhu zvakaputirwa pamusoro peiyo organic lens.Nekudaro, nekuda kwekusiyana kwemafuta ekuwedzera coefficients ezviviri izvi, iyo coating iri nyore kudonha uye brittle, uye kupfeka kupikisa mhedzisiro hakuna kunaka.Chizvarwa chitsva chetekinoroji chichaonekwa makore gumi ega ega mune ramangwana, uye yazvino kupfeka-inodzivirira coating ndeye yakasanganiswa firimu layer ye organic matrix uye inorganic particles.Iyo yekare inovandudza kuoma kwefirimu inopfeka, uye iyo yekupedzisira inowedzera kuoma.Iko kunzwisisika kusanganiswa kwezviviri kunowana yakanaka kupfeka-resistant maitiro.
Anti-reflection coating
Malenzi atinopfeka akafanana nemagirazi akadzikama, uye chiitiko chechiedza chiri pamusoro pemagirazi egirazi chicharatidzawo.Mune zvimwe zviitiko, zviratidzo zvinogadzirwa nema lens edu zvinogona kukanganisa kwete chete muchengeti asiwo munhu anotarisa kune anopfeka, uye panguva dzakaoma, chiitiko ichi chinogona kutungamirira kune zviitiko zvikuru zvekuchengetedza.Nokudaro, kuitira kuti udzivise kukuvadza kunokonzerwa nechiitiko ichi, anti-reflection mafirimu akagadzirwa.
Anti-reflection coatings inobva pakuchinja uye kupindira kwechiedza.Kutaura zviri nyore, iyo anti-reflection firimu yakaputirwa pamusoro peiyo lens yekuona, kuitira kuti chiedza chinotaridzirwa chinogadzirwa nechemberi uye kumashure kwemufirimu chinopindirana, nokudaro kubvisa chiedza chinoratidzwa uye kubudirira kwekuita. anti-reflection.
Anti-fouling firimu
Mushure mekunge iyo lens yepamusoro yakaputirwa ne-anti-reflection coating, zvakanyanya nyore kusiya mavara.Izvi zvichaderedza zvakanyanya "anti-reflection kugona" uye kugona kwekuona kwelens.Chikonzero cheizvi ndechekuti iyo anti-reflection coating layer ine microporous chimiro, saka imwe yakanaka guruva uye mafuta mavara anosiiwa zviri nyore pane lens pamusoro.Mushonga wechiitiko ichi ndeyekupfekedza firimu repamusoro pamusoro pefirimu rinopesana, uye kuitira kuti usaderedze kukwanisa kwefirimu inopikisa, hupamhi hwehuputi hunoda hutete zvikuru.
Lenzi yakanaka inofanira kunge iine firimu rinoumbwa nezvikamu zvitatu izvi, uye kuitira kuti riwedzere kugona kufungidzira, panofanira kuva nezvikamu zvakawanda zvemafirimu anopikisa akaiswa pamusoro.Kazhinji kutaura, ukobvu hweiyo inomira-inodzivirira layer i3 ~ 5um, iyo multilayer anti-reflection firimu inosvika 0.3 ~ 0.5um, uye iyo thinnest antifouling firimu i0.005um ~ 0.01um.Kurongeka kwefirimu kubva mukati kusvika kunze ndeyekupfeka-kusagadzikana, iyo yakawanda-layer anti-reflection coating uye anti-fouling film.
