Izinto zeplastiki kunye nenaliti yesifo sisiseko seelensi ezincinci. Ubume beelensi zeplastiki zibandakanya izinto ze-lens, iLensi Barrel, i-Lens Mount, Spacer, iSpeding Pheet, uxinzelelo lwe-imeyile, njl.

Zininzi iindidi ze-lens ze-lensi zeelensi zeplastiki, zonke ezinokuthi zicace iplastiki (i-polecular ephezulu). Bangama thermoplastics, iiplasitiki ezithambileyo kwaye ziba seplastikini xa ifudumele, ilukhuni xa ipholile, kwaye ikhathazeke xa iphilile. Utshintsho lomzimba oluvelisa utshintsho olubuyela umva phakathi kolwelo kunye namazwe aqinileyo usebenzisa ubushushu kunye nokupholisa. Ezinye izinto zayenziwe ngaphambili kwaye ezinye zintsha. Ezinye ziiplastiki ezisebenza ngokubanzi, kwaye ezinye izixhobo ziphuhliswe ngokukodwa izixhobo zeplasitiki, ezisetyenziswa ngokuthe ngqo kumasimi athile.

Kwindlela yokukhanya, sinokubona amabakala ombane eenkampani zeenkampani ezahlukeneyo, ezinje nge-EP8000, K26R, APL5015, okp-1 njalo njalo. Zonke zezoba luhlobo oluthile lweplastiki, kwaye ezi ntlobo zilandelayo zixhaphake ngakumbi, kwaye siya kuzilungisa ngokwexesha labo lokubonakala:

Iilensi zeplastiki

• l pmma / prylic:I-Poly (i-methyl metacrylate), i-polymethyl metacrylate (Plexiglass, Acrylic). Ngenxa yexabiso layo eliphantsi, ukuhambisa phezulu, kunye namandla amakhulu oomatshini, i-PMMA yeyona nto ixhaphakileyo ebomini. Uninzi lweplasitiki yenziwa nge-PMMA, njengeeplate ezibonakalayo, iicomputer ezibonakalayo, kunye nee-leds ezincinci. Ilensi njl njl. I-PMMA iveliswe ngobunzima ukusukela nge-1930s.
• I-PS:I-polystyrene, i-polystyrene, yi-thermoplastic engenabala kwaye ebonakalayo, kunye neplastiki yobunjineli, eyaqala imveliso enkulu nge-1930s. Uninzi lweebhokisi ze-fight ezimhlophe kunye neebhokisi zesidlo sasemini ezixhaphakileyo ebomini bethu zenziwa ngezinto zePS.
• I-PC:I-Polycarbonate, iPolycarbonate, ikwayinto engaqhelekanga nengacacanga ne-amorphous thermoplastic, kwaye ikwayindlela ethile eqhelekileyo yeplastiki. Yayiqhutywa nje ezemizi-mveliso ngonyaka we-1960 kuphela. Ukunganyangeki kwempembelelo kwezinto zePC kulungile kakhulu, izicelo eziqhelekileyo zibandakanya iibhakethi zokuhambisa amanzi, iigoggles, njl.
• l Khokelela & COC:I-cyclic olefin polymer (ikopi), i-olefin ye-olefin; I-Cyclin Olefin Copolymer (COC) i-Olefin ye-Olefin, yi-amorser ye-polymer ebonakalayo ye-racbon ye-hidrocarhers ye-cyclin ye-cyclic ye-cyclin ye-cyclin ye-cyclin (cop) okanye i-copolymerization (CoC ) Ezinye iimolekyuli (ezinjenge zethylene). Iimpawu zekopi kunye ne-coc ziphantse zafana. Esi sixhobo sitsha. Xa yaqala ukwenziwa, yayithathwa njengezinye izicelo ezinxulumene nolwakhiwo. Ngoku isetyenziswa ngokubanzi kwifilimu, iilensi zokukhetha, ukubonisa, ezonyango (ezonyango) amashishini. Ikopi igqitywe imveliso yemizi-mveliso malunga no-1990, kwaye i-COC yagqiba imveliso yeshishini ngaphambi kwe-2000.
• l O-Pet:I-Pontusical Polyester ye-polyester fiber, i-O-Pet yayirhweba e-Osaka ngo-2010.

Xa uhlalutya umxholo we-optical, sibandakanyeka ikakhulu ziipropathi zabo zokukhanya kunye noomatshini.

• Isalathiso sokuqaqamba kunye nokusasazwa

Isalathiso sokuqaqamba kunye nokusasazwa

Ingabonwa kwesi sishwankathelo semizobo eyahlukileyo yeplasitiki eyahlukeneyo iwela kwizithuba ezibini: Iqela elinye lisalathiso esiphezulu sokuqaqamba kunye nokusasazeka okuphezulu; Eli qela lisezantsi lesalathiso esiphantsi kunye nokusasazeka okuphantsi. Ukuthelekisa uluhlu lwesalathiso sesalathiso kunye nokusasazeka kwezixhobo zeglasi, siya kufumanisa ukuba uluhlu lwesalathiso se-Replaces lezixhobo zeplastiki zinqabile, kwaye zonke izinto zeplastiki zinesalathiso esisezantsi se-Recaication. Ngokubanzi, uluhlu lweenketho zezinto zeplastiki zincinci, kwaye zingama-20 kuphela amabakala ezilwanyana, ezingama-20 kuphela ezinokuthintela inkululeko yoyilo lwezinto.

I-Recande Is Index ye-Wavelength: Isalathiso sokuqaqamba kwezinto zeplastiki enyukayo nge-wavelength, i-Inden yesalathiso iyancipha kancinci, kwaye iyonke izinzile.

Ukutshintsha kwesalathiso sesalathiso seqondo lokushisa i-DN / DT: Ubushushu bokusebenza kwisalathiso se-tistic seplastiki ngamaxesha angama-6 amakhulu, oko kuthetha ukuba njengoko iqondo lokushisa liyanda, isalathiso sentshabalalo siyancipha. Umzekelo, kwi-Waveeth ye-546nm, -20 ° C ukuya kwi-40 ° C, ixabiso le-DN / DT lezinto zeplastiki ze-Is -8 ukuya -1 / ° C, ngelixa iXesha leGlasi I-NBK7 yi-3x10 ^ -6 / ° C.

• Ukudlulisa

Ukudlulisa

Ukubhekisa kulo mfanekiso, uninzi lweeplastiki zine-factotics idluliselo olungaphezulu kwe-90% kwibhendi ekhanyayo ebonakalayo; Baye basebenza kakuhle kwiibhendi ezingama-850NM kunye ne-940NM, ezixhaphakileyo kwi-elektroniki yabathengi. Ukudluliselwa kwezinto zeplastiki kuya kuncipha kwinqanaba elithile kunye nexesha. Esona sizathu kukuba iplastiki ifumana i-ultraviolet i-Ultraviolet eLanga, kwaye i-chain ye-molecular yeyaphula i-Degrade kunye nekhonkco elinqamlezileyo, olubangela utshintsho kwiipropathi zomzimba kunye nekhemikhali. Eyona nto ibonakalisayo ibonakale ngokucacileyo kukutyhoboza kweplastiki.

• Uxinzelelo lwe-BIRFRICHEENCE

I-Lens Ready

Uxinzelelo lwe-BIRFRFRENECEART Isalathiso semigangatho yezinto sihambelana nemeko yokulinganisa kunye nendlela yokusasazeka kokukhanya kwemeko. Izixhobo zibonisa ii-indices ezahlukeneyo zokuvuselelwa kwamagama ahlukeneyo okulinganisa. Kwezinye iinkqubo, oku kuphambuka kwesalathiso semali mncinci kakhulu kwaye akunayo impembelelo enkulu kwinkqubo, kodwa ngenxa yeenkqubo ezizodwa zenkqubo, oku kuphala kwanele ukubangela ukonakaliswa okukhulu kwenkqubo yokusebenza kwenkqubo.

Izinto zeplasitiki azinazo iimpawu ze-anisotropic, kodwa inaliti ebunjiweyo yeplastiki ziya kwazisa uxinzelelo lwe-charfrieveence. Esona sizathu sisityholo esiziswayo ngexesha lokuxhuzulwa kwenaliti kunye nolungiselelo lwe-macromolecules yeplastiki emva kokuphola. Uxinzelelo ngokubanzi lugxile ngokubanzi kufutshane ne-ination port, njengoko kubonisiwe kumzobo ongezantsi.

Uyilo ngokubanzi kunye nemveliso kukunciphisa uxinzelelo kwindiza efanelekileyo, efuna uyilo olufanelekileyo lwesakhiwo, inaliti yokubumba kunye nemveliso. Phakathi kwezinto ezininzi ze-PC, izixhobo zePC zithambekele kakhulu kuxinzelelo lwe-birefringence (malunga nezihlandlo ezili-10 ezinkulu kunezixhobo ze-PMMA), kwaye i-POC, i-COC, kunye ne-PMMA ye-PMMA inoxinzelelo olusezantsi.
