Kev ua haujlwm ntawm optical coaters feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no: pretreatment, txheej, kev saib xyuas zaj duab xis thiab hloov kho, txias thiab tshem tawm. Cov txheej txheem tshwj xeeb yuav txawv nyob ntawm cov khoom siv (xws li evaporation coater, sputtering coater, thiab lwm yam) thiab txheej txheej txheej (xws li ib txheej zaj duab xis, zaj duab xis multilayer, thiab lwm yam), tab sis feem ntau, txheej txheem ntawm cov txheej txheem kho qhov muag yog roughly raws li hauv qab no:
Ua ntej, theem kev npaj
Ntxuav thiab npaj cov khoom siv kho qhov muag:
Ua ntej txheej txheej, cov khoom siv kho qhov muag (xws li lo ntsiab muag, cov ntxaij lim dej, iav kho qhov muag, thiab lwm yam) yuav tsum tau ntxuav kom huv si. Cov kauj ruam no yog lub hauv paus rau kev ua kom zoo ntawm cov txheej txheem. Feem ntau siv txoj kev tu muaj xws li ultrasonic tu, pickling, chav tu thiab lwm yam.
Cov khoom siv kho qhov muag huv si feem ntau yog muab tso rau ntawm lub tshuab tig lossis clamping system ntawm lub tshuab txheej kom ntseeg tau tias lawv tuaj yeem nyob ruaj khov thaum lub sijhawm txheej txheej txheej.
Pretreatment ntawm lub tshuab nqus tsev vacuum:
Ua ntej muab cov khoom siv kho qhov muag rau hauv lub tshuab txheej, cov txheej txheem yuav tsum tau muab tso rau hauv ib qho kev nqus ntawm lub tshuab nqus tsev. Lub tshuab nqus tsev ib puag ncig tuaj yeem tshem tawm impurities, oxygen thiab dej vapor hauv huab cua, tiv thaiv lawv los ntawm kev cuam tshuam nrog cov khoom txheej, thiab xyuas kom meej qhov purity thiab zoo ntawm cov yeeb yaj kiab.
Feem ntau, txheej txheej yuav tsum ua kom tiav lub tshuab nqus tsev siab (10⁻⁵ rau 10⁻⁶ Pa) lossis lub tshuab nqus tsev nruab nrab (10⁻³ txog 10⁻⁴ Pa).
Thib ob, txheej txheej txheej
Pib txheej qhov chaw:
Cov txheej txheej feem ntau yog qhov chaw evaporation lossis sputtering qhov chaw. Cov txheej txheej sib txawv yuav raug xaiv raws li txheej txheem txheej thiab cov khoom siv.
evaporation qhov chaw: Cov khoom siv txheej yog rhuab mus rau lub xeev evaporative siv cov khoom siv cua sov, xws li cov kab hluav taws xob hluav taws xob evaporator lossis lub tshuab cua sov ua kom sov, kom nws cov molecules lossis atoms evaporate thiab muab tso rau saum npoo ntawm cov khoom siv kho qhov muag hauv lub tshuab nqus tsev.
Sputtering qhov chaw: Los ntawm kev siv lub high voltage, lub hom phiaj collides nrog ions, sputtering tawm lub atoms los yog molecules ntawm lub hom phiaj, uas yog deposited nyob rau saum npoo ntawm lub optical keeb los ua ib tug zaj duab xis.
Film material deposition:
Nyob rau hauv ib qho chaw nqus tsev, cov khoom coated evaporates los yog sputters los ntawm ib qhov chaw (xws li evaporation qhov chaw los yog lub hom phiaj) thiab maj mam tso rau ntawm qhov chaw ntawm qhov chaw kho qhov muag.
Lub deposition npaum li cas thiab zaj duab xis thickness yuav tsum tau precisely tswj los xyuas kom meej tias cov zaj duab xis txheej yog uniform, tas mus li, thiab ua tau raws li qhov yuav tsum tau tsim. Kev tsis sib xws thaum lub sij hawm tso tawm (xws li tam sim no, roj ntws, kub, thiab lwm yam) yuav cuam tshuam ncaj qha rau cov yeeb yaj kiab zoo.
Kev saib xyuas zaj duab xis thiab thickness tswj:
Nyob rau hauv txheej txheej txheej, lub thickness thiab zoo ntawm cov zaj duab xis yog feem ntau saib nyob rau hauv lub sij hawm, thiab feem ntau siv cov cuab yeej saib xyuas yog quartz siv lead ua microbalance (QCM) ** thiab lwm yam sensors, uas yuav raug kuaj xyuas tus nqi deposition thiab thickness ntawm cov zaj duab xis.
Raws li cov ntaub ntawv soj ntsuam no, lub kaw lus tuaj yeem hloov kho qhov tsis xws li lub zog ntawm cov txheej txheej, cov pa roj ntws los yog qhov kev sib hloov ceev ntawm cov khoom kom tswj tau qhov sib xws thiab sib xws ntawm cov yeeb yaj kiab txheej.
Multilayer zaj duab xis (yog tias xav tau):
Rau cov khoom siv kho qhov muag uas xav tau cov qauv ntau txheej, txheej txheej txheej feem ntau yog ua los ntawm txheej txheej. Tom qab kev tso tawm ntawm txhua txheej, lub kaw lus yuav ua kom rov ua cov yeeb yaj kiab tuab thiab kho kom ntseeg tau tias qhov zoo ntawm txhua txheej ntawm zaj duab xis ua tau raws li qhov yuav tsum tau ua.
Cov txheej txheem no yuav tsum muaj kev tswj xyuas meej ntawm cov tuab thiab cov khoom siv ntawm txhua txheej kom ntseeg tau tias txhua txheej tuaj yeem ua haujlwm xws li kev xav, kev xa mus lossis cuam tshuam hauv ib qho kev sib txawv wavelength.
Thib peb, txias thiab tshem tawm
CD:
Tom qab txheej txheej tiav lawm, lub optics thiab lub tshuab txheej yuav tsum tau txias. Txij li cov khoom siv thiab cov khoom siv tuaj yeem ua rau kub thaum lub sijhawm txheej txheej txheej, lawv yuav tsum tau txias rau hauv chav sov los ntawm lub tshuab ua kom txias, xws li cov dej txias lossis cua ntws, kom tsis txhob muaj kev puas tsuaj rau thermal.
Hauv qee qhov txheej txheem txheej txheej kub kub, txias tsis tsuas yog tiv thaiv cov khoom siv kho qhov muag, tab sis kuj tseem ua rau cov yeeb yaj kiab kom ua tiav qhov kev pom zoo thiab kev ruaj ntseg.
Tshem tawm cov khoom siv kho qhov muag:
Tom qab txias tiav lawm, cov khoom siv kho qhov muag tuaj yeem raug tshem tawm ntawm lub tshuab txheej.
Ua ntej yuav tawm, nws yog ib qho tsim nyog yuav tau xyuas cov nyhuv txheej, nrog rau cov txheej txheem ntawm cov zaj duab xis, cov thickness, adhesion, thiab lwm yam.
4. Tom qab ua tiav (yeem)
Zaj duab xis hardening:
Qee lub sij hawm coated zaj duab xis yuav tsum tau hardened los txhim kho qhov khawb kuj thiab durability ntawm zaj duab xis. Qhov no feem ntau yog ua los ntawm kev siv xws li kev kho cua sov lossis hluav taws xob ultraviolet.
Kev ntxuav zaj duab xis:
Txhawm rau tshem tawm cov kab mob, cov roj los yog lwm yam impurities los ntawm qhov chaw ntawm zaj duab xis, nws yuav tsum tau ua me me tu, xws li ntxuav, kho ultrasonic, thiab lwm yam.
5. Kev soj ntsuam zoo thiab kev sim
Kev ntsuas qhov muag pom: Tom qab txheej txheej tiav, kev ntsuas kev ua tau zoo tau ua tiav ntawm cov khoom siv kho qhov muag, suav nrog lub teeb xa hluav taws xob, kev cuam tshuam, kev ua yeeb yaj kiab, thiab lwm yam, kom ntseeg tau tias nws ua tau raws li cov kev xav tau.
Adhesion test: Los ntawm kev kuaj kab xev los yog khawb, xyuas seb qhov adhesion ntawm zaj duab xis thiab substrate puas muaj zog.
Environmental stability testing: Qee lub sij hawm nws yog ib qho tsim nyog yuav tsum tau ua qhov kev ntsuam xyuas kev ruaj ntseg nyob rau hauv ib puag ncig xws li kub, av noo, thiab ultraviolet lub teeb kom ntseeg tau qhov kev ntseeg ntawm cov txheej txheej hauv kev siv tswv yim.
