Cov ntaub ntawv yas thiab txhaj tshuaj moulding yog lub hauv paus rau cov lenses miniatures. Cov qauv ntawm cov yas yas suav nrog cov ntawv sau loces, lens barrrel, lens mount, spacer, cov ntaub ntawv shading, thiab lwm yam khoom siv thiab lwm yam.

Muaj ntau hom khoom siv lens rau cov ntsiab muag yas, txhua yam uas yog qhov tseem ceeb yas (siab molecular polymer). Lawv yog thermoplastics, plastics uas soften thiab ua cov yas thaum ua kom sov, ua kom txias thaum txias, thiab muag muag thaum rhuab ntxiv. Kev pauv hloov lub cev uas tsim cov kev hloov pauv hloov ntawm cov kua thiab cov khoom siv tau siv cov cua sov thiab cua txias. Qee cov ntaub ntawv tau tsim ua ntej thiab qee qhov tseem tshiab. Ib txhia yog cov ntaub ntawv dav dav-lub hom phiaj, thiab qee cov ntaub ntawv tau tsim kho cov khoom siv roj txawv li cas, uas tau siv ntau dua hauv qee thaj teb kho qhov muag.

Hauv kev tsim qauv kho qhov muag, peb yuav pom cov khoom ntawm ntau cov tuam txhab, xws li EP8000, K26R, APL5015, Okp-1 thiab lwm yam. Lawv txhua tus koom nrog cov khoom siv yas, thiab cov hom hauv qab no yog ntau dua, thiab peb yuav txheeb lawv raws li lawv lub sijhawm zoo li:

Cov Lus Qhia Yas

• l PMMA / Acrylic:Poly (methyl methacrylate), polymethyl methamrylate (PleXiglass, Acrylic). Vim nws tus nqi pheej yig, kev hloov siab, thiab muaj zog dua, PMMA yog cov iav hloov hauv lub neej. Feem ntau ntawm cov pob tshab plastics yog ua los ntawm PMMA, xws li cov phiaj pob tshab, pob tshab, thiab cov tsiaj me me. Lens ESC. PMMA tau muaj feem ntau-tsim txij li xyoo 1930.
• PS:Polystyrene, polystyrene, yog ib qho tsis muaj xim thiab pob tshab thermoplastic, nrog rau cov tshuab yas, uas tau pib ntau ntau xyoo 1930. Ntau lub thawv ntim npuas dej dawb thiab cov thawv su uas muaj ntau hauv peb lub neej yog ua los ntawm cov ntaub ntawv PS.
• Lub PC:Polycarbonate, Polycarbonate, kuj yog ib qho tsis muaj xim thiab pob tshab amorphous thermopastic, thiab nws kuj yog ib lub hom phiaj dav dav. Nws tsuas yog muaj nyob hauv 1960s. Qhov cuam tshuam tsis kam ntawm cov khoom siv PC tau zoo heev, cov kev siv ntau suav nrog cov chaw tso dej Dispenser, Goosgles, thiab lwm yam.
• l cop & co:Cyclic olin polymer (cop), cyclic co polinter; Cyclic OlefinPer (co) Cyclic Olefinymer, yog ib qho khoom siv hluav taws xob polymer, nrog cov pa roj polliccerization (cop) lossis copolymerization (cocolymerization (cocolymerization) ) Nrog lwm cov molecules (xws li ethylene). Cov yam ntxwv ntawm cop thiab coc yog yuav luag zoo ib yam. Cov ntaub ntawv no yog tus tshiab. Thaum nws tau tsim thawj zaug, nws yog feem ntau suav nrog rau qee qhov kev siv kho qhov muag siv. Tam sim no nws yog dav siv hauv zaj duab xis, kho qhov muag, tso saib, kev kho mob (ntim fwj) kev lag luam. COP Ua tiav kev lag luam Kev Lag Luam Kev Lag Luam Kev Lag Luam Kev Lag Luam Xyoo 1990
• l o-tsiaj:Optical Polyester kho cov neeg muaj txiaj ntsig polyester fiber ntau, O-tsiaj tau ua lag luam hauv Osaka hauv xyoo 2010.

Thaum kev tshuaj xyuas cov khoom siv kho kab mob kho qhov muag, peb feem ntau muaj kev txhawj xeeb nrog lawv cov khoom siv kho tshiab thiab cov neeg kho tshuab.

Optical Pkev kub siab

• Refuntion Index & Dispersion

Refuntion Index thiab Dispersion

Nws tuaj yeem pom los ntawm cov ntaub ntawv sib tw no uas tau siv cov ntaub ntawv siv roj hmab sib txawv Lwm pab pawg yog qhov ntsuas kom tsawg dua thiab tsis muaj kev cuam tshuam. Muab piv cov kev xaiv tau ntawm cov ntaub ntawv tsis muaj cov iav, peb yuav pom tias qhov kev xaiv cov ntaub ntawv yas, thiab tag nrho cov khoom siv roj hmab kom muaj qhov ntsuas qis dua. Feem ntau hais lus, cov kev xaiv rau cov yas yas uas nqaim, thiab tsuas yog txwv cov qib kev ywj pheej ntawm cov khoom tsim kho.

Cov ntaub ntawv sau ua hluav taws xob sib txawv: Cov ntaub ntawv hluav taws xob hloov kho cov khoom siv roj hmab roj hmab roj hmab roj hmab roj ntxiv rau me ntsis, thiab cov zuag qhia tag nrho yog qhov ruaj khov.

Kev hloov kho qhov ntsuas kub DN / DN: Qhov ntsuas kub tshaj plaws yog 6 npaug ntawm qhov ntsuas tsis zoo, uas yog qhov ntsuas kub nce ntxiv, cov khoom siv hluav taws xob nce. Piv txwv li, rau nthwv cua 546NM, -20 ° C txog 40 ° C, DT tus nqi ntawm cov khoom siv yas yog -8 rau -15-thaum lub sij hawm ntawm cov khoom siv iav NBK7 yog 3x10 ^ -6 / ° C.

• Kev hloov pauv

Kev hloov pauv

Xa mus rau daim duab no, feem ntau saib xyuas cov plastics muaj kev hloov pauv ntawm ntau dua 90% hauv kev pom band; Lawv kuj tau hloov pauv tau zoo rau cov kev sib txuas lus infrared ntawm 850nm thiab 940nm, uas yog ib txwm muaj nyob rau hauv cov neeg siv khoom hluav taws xob. Kev sib txuas ntawm cov ntaub ntawv yas yuav tseem txo qis rau qee yam nrog lub sijhawm. Lub ntsiab yog tias cov yas nqus ntawm ulaviolet rays nyob rau hauv lub hnub, thiab cov kab molecular ris los ua kom tsis txaus ntseeg thiab txuas rau hauv kev hloov pauv ntawm lub cev thiab tshuaj lom neeg. Qhov pom tseeb ntawm macroscopic manifestation yog yellowing ntawm cov khoom siv yas.

• Kev ntxhov siab Birefringence

Lens Reftraction

Kev ntxhov siab Birefringence (Birgringence) yog cov khoom siv kho kho qhov muag. Cov ntaub ntawv ua haujlwm tshiab ntawm cov ntaub ntawv yog cuam tshuam nrog lub xeev polarization thiab kev sib tw ntawm kev taw qhia teeb. Cov ntaub ntawv nthuav qhia qhov sib txawv ntawm qhov tseeb ntawm cov qib siab sib txawv ntawm cov nroog sib txawv. Rau qee lub tshuab, qhov no ua kom muaj kev cuam tshuam me me heev thiab tsis muaj kev cuam tshuam zoo rau cov kab ke, tab sis rau qee qhov kev txawv tshwj xeeb, qhov kev sib txawv no txaus los ua rau kev ua haujlwm hnyav ntawm kev ua haujlwm.

Cov ntaub ntawv yas lawv tus kheej tsis muaj anisotropic cov yam ntxwv, tab sis txhaj tshuaj molding ntawm plastics yuav ua kom paub cov kev ntxhov siab. Qhov laj thawj tseem ceeb yog kev ntxhov siab qhia thaum txhaj tshuaj molding thiab kev npaj cov tshuab yas macromolecules tom qab txias. Qhov kev ntxhov siab feem ntau muaj nyob ze ntawm qhov kev txhaj tshuaj nres nkoj, raws li qhia hauv daim duab hauv qab no.

Tus qauv tsim qauv thiab cov ntsiab cai tsim tau yog txo qhov kev ntxhov siab ntawm lub lens qauv, txhaj tshuaj molding pwm thiab ua ntau yam tsis muaj cov cwj pwm. Ntawm ntau cov ntaub ntawv, cov ntaub ntawv PC muaj ntau dua rau kev ntxhov siab (txog 10 zaug loj dua li pmma cov ntaub ntawv), thiab cop, co ntswg muaj cov kev ntxhov siab tsawg dua.
