Ibikoresho bya plastike no kubumba inshinge ni ishingiro ryinzira nto. Imiterere ya lens ya plastiki irimo ibikoresho, lens barrel, lens imusozi, spacer, urupapuro rwerekana, ibikoresho byumuvuduko, nibindi.

Hariho ubwoko bwinshi bwa lens ibikoresho byinzira ya plastike, byose byacyo ni plastike (umuvuduko mwinshi. Ni thermoplastike, plastiki koroshya kandi bahinduka plastiki mugihe ushyushye, ukomera iyo ukonje, kandi koroshya iyo wongeye gukara. Impinduka zumubiri zitanga impinduka zishingiye kuri leta nibisohoka neza ukoresheje gushyushya no gukonjesha. Ibikoresho bimwe byahimbwe mbere kandi bimwe ni bishya. Bamwe ni intego rusange ya plastikis, nibikoresho bimwe byatejwe imbere ibikoresho bya plastiki bya optique, bikoreshwa cyane mumirima imwe ya optique.

Mu buryo bwa optique, dushobora kubona inama yibikoresho byamasosiyete atandukanye, nka EP0000, K26R, APL5015, OKP-1 nibindi. Bose bari mubwoko runaka bwibikoresho bya shositike, kandi ubwoko bukurikira burasanzwe, kandi tuzabatondaho dukurikije igihe cyagaragaye:

Lens ya pulasitike

• l pmma / acrylic:Poly (methyl methacrylate), Polymethyl Methacrylate (Plexiglass, Acrylic). Bitewe nigiciro cyacyo gihenze, gucika bugufi, nimbaraga nyinshi zubukanishi, pmma nicyo gisimbuza ikirahure gisanzwe mubuzima. Ibyinshi muri plastike iboneye bikozwe muri pmma, nkisahani yumurongo, ibiyiko bisobanutse, na LED nto. Lens nibindi PMMA yakozwe nabi kuva 1930.
• PS:Polystyrene, Polystyrene, ni ibara ritagira ibara kandi rifite agaciro, kimwe na pulasitike yubuhanga, itangira kubyara muri 1930. Benshi mu masoko berekeje hamwe n'amasanduku ya sasita bikunze kugaragara mubuzima bwacu bikozwe mubikoresho bya P Zab.
• PC:Polycarbonate, Polycarbonate, nabyo ni ibara kandi rifite agaciro rya amorhous, kandi nuburyo na plastiki rusange. Byagize uruhare gusa muri za 1960. Kurwanya ingaruka yibikoresho bya PC ni byiza cyane, harimo ikoreshwa ryimbeba za Dispenser Amazi, Goggles, nibindi.
• l Kop & Coc:Cyclic olefin polymer (umupolisi), cyclic olemer; Cyclic olefin copolymer (coc) cyclic olefin copolymer, ni amorphous itwara impeta, hamwe na karubone-carbone ) hamwe nabandi molekile (nka royoy). Ibiranga kopi na coc biramwe. Ibi bikoresho ni bishya. Iyo byahimbwe bwa mbere, byasuzumwe cyane cyane kubisabwa. Noneho birakoreshwa cyane muri firime, lens optique, kwerekana, kubuvuzi (gupakira amacupa). Umupolisi warangije inganda hafi ya 1990, kandi Coc yarangije umusaruro w'inganda mbere ya 2000.
• l O-Pet:Optique Polyester Optique Optique fibre, O-Pet yari yakosowe i Osaka muri 2010.

Iyo dusesenguye ibintu bya optique, duhangayikishijwe cyane cyane na optique zabo na mashini.

• Indangagaciro & gutatanya

Indangagaciro no gutatanya

Birashobora kugaragara muriyi ncamake yibishushanyo mbonera bya plastike bya plastiki bya optique bigabanuka muburyo bubiri: itsinda rimwe ni indangagaciro ndende kandi itana hejuru; Irindi tsinda ni urutonde ruto rwo kumvikana no gutatanya hasi. Kugereranya urutonde rwibipimo ngenderwaho no gutatanya ibikoresho byikirahure, tuzabona ko urutonde rwibipimo bidahitamo ibikoresho bya plastike bigufi, nibikoresho byose bya plastiki bifite indangagaciro nke ugereranije. Muri rusange, uburyo butandukanye bwo gukoresha ibikoresho bya pulasitike ni bigufi, kandi hari amanota 10 kugeza kuri 20 yubucuruzi, ahanini bigabanya ubwisanzure bwibikoresho bya Optique mubikoresho.

Indanganturo irobanura iratandukanye hamwe nuburebure bwumuraba bwa pulasitike optique yiyongera hamwe nuburebure bwumuraba, itandukaniro rigabanuka gato, kandi muri rusange birahagaze neza.

Indangagaciro zinyongera hamwe nubushyuhe DN / DT: Ubushyuhe bwubushyuhe bwo kumvikana ni inshuro 6 kugeza ku kirahure, bivuze ko uko ubushyuhe bugabanuka bugabanuka. Kurugero, ku burebure bwa 546NM, -20 ° C kugeza 40 ° C, Agaciro ka DN / DT kuri -15 / ° AKAZI KABANYAHA NBK7 ni 3x10 ^ -6 / ° C.

• Gufata

Gufata

Kuvuga kuri iyi shusho, plastique nziza cyane ifite kohereza inshuro zirenga 90% mumatsinda agaragara; Bafite kandi uruhare rwiza ku bayobozi barengeje 850nm na 940Nm, bikunze kugaragara mu mashanyarazi y'abaguzi. Gufatanya ibikoresho bya plastike bizagabanuka kandi kurwego runaka. Impamvu nyamukuru nuko plastike ikurura imirasire ya ulstique izuba, kandi urunigi rwa molekile ruvamo gutesha agaciro no kwambukiranya, bikavamo impinduka mumitungo yumubiri na shimi. Kugaragaza Macroscopic cyane ni umuhondo wibikoresho bya plastiki.

• Guhangayikishwa

Lens

Stress Birefringence (Birefringence) numutungo mwiza wibikoresho. Index irongera igenamigambi ifitanye isano no kwerekana icyerekezo cya leta no gukwirakwiza icyerekezo cyabaye. Ibikoresho byerekana ibipimo bitandukanye byo gutunganya ibihugu bitandukanye. Kuri sisitemu zimwe, iyi decration yo gutandukana ni nto cyane kandi ntabwo ifite ingaruka zikomeye kuri sisitemu, ariko kuri sisitemu yihariye ya optique, iyi deolation irahagije kugirango iteshegure ibintu bikomeye imikorere ya sisitemu.

Ibikoresho bya plastiki ubwabo ntabwo bifite ibiranga anisotropique, ariko gushimura plastike bizatangiza imihangayiko. Impamvu nyamukuru ni guhangayikishwa mugihe cyo kubumba hamwe na gahunda ya Macronolecules nyuma yo gukonja. Guhangayikishwa muri rusange byibanda ku cyambu cya inshinge, nkuko bigaragara ku gishushanyo gikurikira.

Ihame rusange nigikorwa rusange ni ukugabanya intambwe yo guhangayikishwa nindege nziza, bisaba igishushanyo mbonera cyimiterere ya Lens, gutemba imisoro, gutemba kubumba no kubyara. Mu bikoresho byinshi, ibikoresho bya PC birakunda guhangayikishwa n'intoki (inshuro 10 kurenza ibikoresho bya Pmma), na kopi, coc, ibikoresho bya Pmma bifite aho birengera imihangayiko.
