Dab tsi yog cov khoom siv rau machining optical element?

Dab tsi yog cov khoom siv dav siv rau machining optical element? Cov khoom siv feem ntau siv rau kev ua cov khoom siv kho qhov muag feem ntau suav nrog cov iav kho qhov muag zoo tib yam, cov khoom siv kho qhov muag, thiab cov khoom siv kho qhov muag.

Kho qhov muag iav

Vim nws yooj yim nkag mus rau siab uniformity ntawm zoo transmittance, nws tau dhau los ua ib qho ntawm cov khoom siv dav tshaj plaws hauv cov khoom siv kho qhov muag. Nws txoj kev sib tsoo thiab txiav ua cov cuab yeej yog cov paub tab, cov ntaub ntawv raw tau yooj yim kom tau, thiab cov nqi ua haujlwm tsawg, yooj yim rau siv; Nws tseem tuaj yeem doped nrog lwm yam tshuaj los hloov nws cov yam ntxwv ntawm cov khoom, thiab cov iav tshwj xeeb tuaj yeem npaj tau, uas muaj qhov tsis tshua muaj melting point, thiab cov spectral kis tau tus mob feem ntau yog concentrated nyob rau hauv lub teeb pom kev thiab nyob ze infrared band.

Optical plastics

Nws yog ib qho tseem ceeb ntxiv cov khoom siv rau cov iav kho qhov muag, thiab nws muaj kev xa tawm zoo nyob rau hauv qhov ze ntawm ultraviolet, pom thiab ze ntawm cov kab infrared. Nws muaj qhov zoo ntawm tus nqi qis, lub teeb yuag, yooj yim tsim thiab muaj zog tiv thaiv, tab sis vim nws qhov loj thermal expansion coefficient thiab tsis zoo thermal stability, nws siv nyob rau hauv complex ib puag ncig yog txwv.

Kho qhov muag siv lead ua

Lub transmittance band ntau ntawm cov khoom siv kho qhov muag yog qhov dav, thiab lawv muaj qhov zoo tshaj plaws hauv kev pom, nyob ze infrared thiab txawm tias ntev yoj infrared.

Kev xaiv cov khoom siv kho qhov muag ua lub luag haujlwm tseem ceeb hauv kev tsim cov duab dav dav. Hauv kev tsim qauv tiag tiag, kev xaiv cov khoom siv feem ntau yog txiav txim siab raws li cov hauv qab no.

Optical khoom

1, cov khoom xaiv yuav tsum muaj kev xa tawm siab hauv cov qhab;

2. Rau cov duab dav dav, cov khoom siv nrog cov yam ntxwv sib txawv feem ntau yog xaiv los kho cov chromatic aberration.

Physicochemical zog

1, qhov ceev ntawm cov khoom, solubility, hardness tag nrho txiav txim siab complexity ntawm cov txheej txheem ntawm lub lens thiab kev siv cov yam ntxwv.

2, lub coefficient ntawm thermal expansion ntawm cov khoom yog ib qho tseem ceeb Performance index, thiab qhov teeb meem ntawm tshav kub dissipation yuav tsum tau txiav txim siab nyob rau hauv lub tom ntej theem ntawm lub system tsim.
