Yuav ua li cas paub qhov txawv iav lo ntsiab muag los ntawm resin lens?

1. Cov khoom siv sib txawv
Lub ntsiab raw khoom ntawm iav lens yog optical iav; Resin lo ntsiab muag yog cov khoom siv organic nrog cov qauv saw hlau polymer sab hauv, uas txuas nrog rau kev tsim cov qauv peb sab. Cov qauv sib xyaw ua ke yog cov xoob xoob, thiab muaj qhov chaw nruab nrab ntawm cov saw hlau molecular uas tuaj yeem tsim kev sib txawv txav.

2. Sib txawv hardness
Cov iav lo ntsiab muag, nrog kev khawb ntau dua li lwm cov ntaub ntawv, tsis yooj yim rau khawb; Qhov saum npoo hardness ntawm lub lens resin yog qis dua li ntawm cov iav, thiab nws yooj yim rau khawb los ntawm cov khoom tawv, yog li nws yuav tsum tau hardened. Cov khoom siv tawv tawv yog silicon dioxide, tab sis lub hardness yuav tsis ncav cuag lub hardness ntawm lub iav, yog li tus neeg hnav yuav tsum tau xyuam xim rau kev saib xyuas ntawm lub lens;

3. Sib txawv refractive index
Lub refractive index ntawm iav lo ntsiab muag yog siab dua li ntawm resin lens, yog li nyob rau hauv tib lub degree, lub iav lens yog thinner dua resin lens. Lub iav lo ntsiab muag muaj cov khoom xa tawm zoo thiab cov khoom siv kho tshuab, qhov ntsuas qhov ntsuas tsis tu ncua thiab ruaj khov lub cev thiab tshuaj lom neeg.
Lub refractive index ntawm resin lens yog nruab nrab. Cov hom CR-39 propylene glycol carbonate muaj qhov cuam tshuam qhov ntsuas ntawm 1.497-1.504. Tam sim no, lub lens resin muag ntawm lub khw tsom iav muaj qhov siab tshaj plaws refractive index, uas tuaj yeem ncav cuag 1.67. Tam sim no, muaj cov iav lo ntsiab muag nrog qhov ntsuas pom ntawm 1.74.

4. Lwm tus
Lub ntsiab raw khoom ntawm iav lens yog optical iav. Nws qhov refractive index yog siab dua li lub lens resin, yog li lub iav lens yog thinner dua li resin lens ntawm tib qib. Lub iav lo ntsiab muag muaj cov khoom xa tawm zoo thiab cov khoom siv kho tshuab, qhov ntsuas qhov ntsuas tsis tu ncua thiab ruaj khov lub cev thiab tshuaj lom neeg. Lub lens tsis muaj xim yog hu ua optical white (dawb), thiab lub lens liab hauv cov xim xim hu ua Croxel lens (liab). Croxel lo ntsiab muag tuaj yeem nqus tau ultraviolet rays thiab me ntsis nqus lub teeb muaj zog.

Resin yog ib hom hydrocarbon (hydrocarbon) tso tawm los ntawm ntau yam nroj tsuag, tshwj xeeb tshaj yog conifers. Vim nws cov qauv tshuaj tshwj xeeb thiab tuaj yeem siv los ua cov xim latex thiab cov nplaum, nws muaj nuj nqis. Nws yog ib qho sib xyaw ntawm ntau yam polymer tebchaw, yog li nws muaj cov ntsiab lus sib txawv. Resin yuav muab faib ua tej yam ntuj tso cob thiab hluavtaws cob. Muaj ntau hom resins, uas tau siv dav hauv tib neeg lub teeb kev lag luam thiab kev lag luam hnyav. Lawv kuj tuaj yeem pom hauv lub neej txhua hnub, xws li yas, iav iav, pleev xim, thiab lwm yam. Resin lens yog lub lens tom qab ua tshuaj lom neeg thiab polishing nrog resin li raw khoom.
