Hauv cov teb uas hloov pauv sai ntawm photonics thiab advanced optics, qhov kev thov rau kev ua tau zoo ntawm cov khoom siv zoo tshaj plaws yeej tsis tau siab dua. Raws li cov kab ke kho qhov muag ua rau muaj kev nyuaj thiab muaj zog ntau dua, kev vam khom rau cov khoom siv txheem feem ntau ua rau muaj kev tsis ruaj khov ntawm thermal thiab poob teeb liab. Qhov no yog qhov uas cov khoom siv iav precision ua lub luag haujlwm tseem ceeb. Rau cov tuam txhab ua haujlwm hauv cov khoom siv kho qhov muag, laser, thiab semiconductor, kev xaiv cov khoom siv iav zoo tsis yog tsuas yog kev txiav txim siab yuav khoom xwb tab sis yog kev xaiv tsim qauv tseem ceeb uas qhia txog lub neej ntev thiab qhov tseeb ntawm tag nrho lub kaw lus.
Ib qho laj thawj tseem ceeb uas cov kws ua vaj tse xaiv cov iav kho qhov muag zoo yog nws qhov ruaj khov tshwj xeeb thaum muaj kev ntxhov siab. Tsis zoo li cov hlau lossis yas, cov iav kho qhov muag zoo muaj kev xa mus rau ntau qhov dav dav, ua kom lub teeb hla dhau nrog kev nqus lossis kev tawg tsawg kawg nkaus. Qhov tseem ceeb tshaj, cov khoom siv iav tshwj xeeb qhia txog qhov coefficient qis ntawm kev nthuav dav thermal. Hauv cov chaw muaj kev ntsuas siab, txawm tias qhov kub thiab txias me me tuaj yeem ua rau cov khoom siv warp, ua rau muaj kev hloov pauv ntawm txoj kev kho qhov muag. Los ntawm kev siv cov iav uas muaj cov yam ntxwv tsis zoo, cov chaw tsim khoom tuaj yeem tswj hwm kev sib dhos thiab kev tsom mus rau qhov tseem ceeb, ua kom ntseeg tau tias lub kaw lus ua haujlwm tas li txawm tias nyob hauv chav kuaj uas tswj hwm huab cua lossis hauv qhov chaw lag luam sib txawv.
Kev siv cov ntaub ntawv no tej zaum yog qhov tseem ceeb tshaj plaws hauv thaj chaw ntawm cov photonics muaj zog siab. Cov khoom siv iav rau cov tshuab laser xav tau kev sib xyaw ua ke ntawm cov khoom, suav nrog cov teeb meem laser siab thiab kev sib xws heev. Hauv kev cim laser, kev txiav, lossis cov khoom siv laser kho mob, cov khoom siv kho qhov muag yuav tsum tiv taus cov zog ntom ntom yam tsis muaj kev puas tsuaj. Fused silica thiab lwm yam tsom iav kho qhov muag tshwj xeeb feem ntau yog cov ntaub ntawv xaiv ntawm no, vim tias lawv txo cov teebmeem thermal lensing uas tuaj yeem cuam tshuam cov teeb laser. Ntxiv mus, hauv semiconductor lithography thiab fiber optic kev sib txuas lus, qhov huv ntawm iav txiav txim siab qhov kev ncaj ncees ntawm lub teeb liab, ua rau cov txheej txheem xaiv cov khoom siv yog qhov tseem ceeb hauv kev ua tiav cov ntaub ntawv siab thiab kev daws teeb meem.
Ua tiav cov theem kev ua tau zoo no xav tau ntau dua li cov khoom siv raw zoo xwb; nws xav tau kev tsim khoom zoo tshaj plaws. Kev ua iav kho qhov muag yog ib qho kev qhuab qhia tshwj xeeb uas hloov cov iav nyoos mus rau hauv cov khoom siv kho qhov muag zoo li cov iav, daim iav, thiab cov prisms. Cov txheej txheem no cuam tshuam nrog kev sib tsoo thiab polishing kom ua tiav qhov roughness ntawm qhov chaw ntawm qib nanometer. Rau cov geometries nyuaj, xws li cov iav aspheric lossis cov iav freeform, cov txheej txheem siab heev xws li kev txhaj tshuaj iav precision. Qhov no tso cai rau kev tsim cov duab nyuaj uas kho cov aberrations zoo dua li cov iav spherical ib txwm muaj, tag nrho thaum tswj hwm qhov kev kam rau siab uas xav tau los ntawm cov software tsim kho qhov muag niaj hnub.
