Hauv kev sib tw mus rau kev nrhiav pom qhov tsis zoo hauv qab micron - txawm tias rau cov iav ntawm lub koob yees duab smartphone, AR / VR optics, lossis semiconductor wafers - cov khoom siv pom kev tshuab tab tom ntsib qhov teeb meem tseem ceeb: kev hloov pauv ntawm lub cev thiab kev tsis ruaj khov ntawm thermal hauv cov khoom siv kho qhov muag uas ua los ntawm hlau. Kev daws teeb meem? Tsiv mus dhau cov khoom siv ib txwm muaj kiag li.
Nkag mus rau cov khoom siv iav meej: cov qauv tsis yog hlau, thermally inert, thiab dimensionally ruaj khov uas tau tsim los ua cov khoom siv kho qhov muag uas txhawb nqa cov kev daws teeb meem siab nrog micron-level fidelity. Ntawm zhhimg, peb tab tom pab cov neeg tsim qauv pom kev ua tiav qhov tseeb ntawm qhov kev tshuaj xyuas tsis tau muaj dua los ntawm kev xav txog qhov "structural" txhais li cas tiag tiag hauv optical metrology.
Vim Li Cas Hlau Thiaj Tsis Tau Zoo Hauv Kev Ua Kom Pom Tseeb Siab
Feem ntau cov tshuab tshuaj xyuas tseem siv txhuas lossis hlau tsis xeb rau cov tuav iav, cov tshuab faib kab teeb, thiab cov phaj siv. Txawm hais tias siv tau tshuab thiab muaj zog, cov hlau raug kev txom nyem los ntawm:
- CTE Siab (12–17 ppm/°C): Ua rau muaj kev hloov pauv ntawm lub dav hlau focal nrog rau kev hloov pauv ntawm qhov kub thiab txias me me li 1°C
- Kev cuam tshuam sib nqus: Cuam tshuam kev sib txuas ntawm lub teeb hluav taws xob lossis theem sib nqus hauv cov kab ke sib xyaw
- Kev Tawm Pa Tawm & Kev Xeb: Ua rau tsis zoo rau chav huv thiab kev ua kom zoo nkauj mus sij hawm ntev
Rau cov chaw tsim khoom siv lens mobile uas tshuaj xyuas cov khoom sib dhos ntau yam ntawm qhov kam rau siab ± 2 µm, txawm tias qhov kev hloov pauv ntawm qhov ntsuas nanometer tuaj yeem ua rau muaj kev tsis lees paub cuav lossis qhov tsis zoo.
Qhov Zoo ntawm Iav: Kev Ruaj Ntseg Ua Rau Hauv Cov Khoom Siv
zhhimg cov khoom siv iav precision—ua los ntawm cov borosilicate uas tsis tshua muaj zog lossis fused silica—yog tsim los ua cov khoom sib xyaw ua ke ntawm optical-mechanical. Cov txiaj ntsig tseem ceeb suav nrog:
- CTE qis li 0.55 ppm/°C (fused silica): Ze li ntawm xoom thermal drift hla 15–35°C kev ua haujlwm ntau yam
- Qhov tiaj tiaj ntawm qhov chaw ≤ λ/10 @ 632.8 nm: Pab kom muaj kev sib koom ua ke ncaj qha raws li cov dav hlau siv lossis cov qhov rai faib kab teeb
- Tsis yog hlau nplaum, tsis yog conductive, xoom outgassing: Zoo tagnrho rau ISO Class 5+ chav huv thiab cov tshuab nqus tsev uas sib xws
- Cov qauv geometries: Kev sib xyaw ua ke ntawm cov mounting bosses, cov yam ntxwv kinematic, thiab cov qauv microstructures tiv thaiv kev cuam tshuam los ntawm kev sib tsoo thiab polishing ultra-precision
Cov no tsis yog cov khoom uas tsis ua haujlwm xwb—lawv yog cov uas ua rau lub kaw lus tshuaj xyuas tsom mus rau qhov tseeb.
Daim Ntawv Thov Tiag: Smartphone Lens AA (Active Alignment) Stations
Ib lub tuam txhab tsim khoom siv xov tooj ntawm tes hauv Suav teb tau hloov kho nws cov kab tshuaj xyuas lub koob yees duab los ntawm kev hloov cov txhuas lens chucks nrog zhhimg cov khoom siv iav kho qhov muag uas muaj cov fiducials thiab cov channel nqus tsev. Cov txiaj ntsig:
- Kev rov ua kom pom tseeb dua tau zoo dua los ntawm ± 1.8 µm mus rau ± 0.4 µm
- Lub sijhawm ua kom lub cev ruaj khov txo qis los ntawm 25 feeb mus rau <3 feeb tom qab pib lub kaw lus
- Tshem tawm kev rov kho dua thaum lub sijhawm ua haujlwm 12 teev vim muaj kev hloov pauv ntawm ib puag ncig
Qhov zais cia? Tag nrho txoj kev pom kev—los ntawm lub hom phiaj mus rau lub phaj sensor—tau tsim los ntawm cov khoom siv iav CTE sib phim, tsim kom muaj ib puag ncig thermal monolithic.
Tsim Koj Lub Tshuab Pom Kev Tom Ntej nrog Iav
zhhimg txhawb nqa cov tshuab pom kev sib koom ua ke nrog cov peev xwm kawg-rau-kawg:
- Kev xaiv cov khoom siv (BK7, B270, fused silica, lwm txoj hauv kev xaiv Zerodur®)
- Kev kam rau siab txog li ± 1 µm ntawm qhov tuab thiab sib luag
- Cov nto npaj txhij rau txheej (Ra < 0.5 nm) rau AR, HR, lossis dichroic txheej
- Daim ntawv pov thawj txhawb nqa los ntawm Metrology raws li ISO 10110
Vim tias nyob rau hauv kev tshuaj xyuas qhov muag pom kev zoo heev, cov qauv yog ib feem ntawm cov optics.
