Nyob rau hauv lub caij nyoog niaj hnub ntawm kev tsim kho tshiab photonic, qhov twg txoj kev laser raug ntsuas hauv nanometers thiab kev teeb tsa optical xav tau qhov ntsiag to kiag li, lub hauv paus ntawm tag nrho lub cev tau dhau los ua qhov kev sib tw engineering tseem ceeb. Raws li cov kev xav tau hauv chaw kuaj mob hauv Tebchaws Europe thiab North America hloov mus rau qhov kev daws teeb meem siab dua thiab kev tau txais cov ntaub ntawv sai dua, cov kev txwv ntawm cov khoom siv kho qhov muag ib txwm muaj thiab cov qauv hlau tau pom tseeb. Qhov no tsa ib lo lus nug tseem ceeb rau cov kws kho qhov muag thiab cov neeg koom ua ke: yuav ua li cas ib tus neeg tuaj yeem ua kom muaj ib puag ncig ruaj khov uas tseem tsis cuam tshuam los ntawm thermal drift thiab micro-vibrations?
Kev lag luam tab tom tig mus rau Granite Platform rau Laser & Optical Systems ua qhov kev daws teeb meem nkaus xwb rau kev ncaj ncees mus sij hawm ntev. Ntawm ZHHIMG, peb tau pom tias cov haujlwm kho qhov muag zoo tshaj plaws yog cov uas muab qhov tseem ceeb rau lub cev substrate ntawm theem tsim qauv thaum ntxov. Lub platform tsis yog ib lub rooj xwb; nws yog tus neeg lav tsis pub leej twg paub ntawm txoj kev kho qhov muag.
Lub Physics ntawm Thermal Passive Stability hauv Optical Engineering
Ib qho ntawm cov teeb meem loj tshaj plaws rau kev teeb tsa laser yog thermal expansion. Hauv cov ntawv thov laser muaj zog heev, txawm tias qhov kub me me uas tsim los ntawm qhov chaw lossis cov khoom siv hluav taws xob nyob ib puag ncig tuaj yeem ua rau cov platforms hlau nthuav dav tsis sib npaug, ua rau lub teeb khiav lossis hloov pauv qhov tsom mus rau. Cov pob zeb granite dub ntuj muaj cov coefficient qis heev ntawm thermal expansion, ua rau nws yog "passive" thermal stabilizer.
Tsis zoo li txhuas lossis hlau, uas teb sai rau kev hloov pauv ntawm ib puag ncig, cov qauv molecular ntom ntom ntawm granite muab cov thermal loj heev. Qhov no tso cai rau Optical Granite Stages kom tswj tau lawv cov geometry ntev dua, xyuas kom meej tias cov interferometers rhiab heev thiab laser cutters tseem calibrated los ntawm thawj teev ntawm kev ua haujlwm mus rau qhov kawg. Rau cov kws tshawb fawb thiab cov engineers industrial, qhov no txhais tau tias tsawg dua downtime rau recalibration thiab kev nce ntxiv ntawm cov ntaub ntawv kev ntseeg siab.
Ua tiav qhov tsis yooj yim sua: Lub ntsiab lus ntawm λ / 10 Flatness Guaranteed
Hauv ntiaj teb ntawm kev ua kom pom tseeb, "qhov tiaj tiaj" feem ntau ntsuas tawm tsam qhov ntev ntawm lub teeb nws tus kheej. Yuav hais tias qhov chaw muaj λ / 10 Flatness Guaranteed yog nkag mus rau qib siab tshaj plaws ntawm kev tsim khoom. Cov lus qhia no txhais tau tias qhov sib txawv ntawm qhov siab tshaj plaws mus rau hav dej thoob plaws tag nrho qhov chaw yog tsawg dua ib feem kaum ntawm qhov ntev ntawm lub teeb siv tshwj xeeb (feem ntau yog HeNe laser ntawm 632.8nm).
Ua tiav qib kev ua tiav ntawm lub platform granite loj no xav tau ntau dua li CNC machining xwb; nws xav tau kev kos duab ib txwm ntawm tes-lapping ua ke nrog kev txheeb xyuas laser interferometric niaj hnub. Ntawm ZHHIMG, peb cov kws kho tshuab siv sijhawm ntau pua teev los kho qhovnto granite, kuaj xyuas thiab rov kuaj xyuas qhov kev nce qib raws li cov qauv NIST-traceable. Cov txheej txheem nruj no ua kom ntseeg tau tias thaum lub theem kho qhov muag tau koom ua ke rau hauv lub tshuab lithography lossis lub tshuab microscope siab, lub hauv paus tsis ua rau muaj kev cuam tshuam me ntsis rau hauv lub wavefront kho qhov muag.
Kev Tiv Thaiv Kev Co thiab Yav Tom Ntej ntawm Cov Theem Optical
Cov txheej txheem laser niaj hnub no feem ntau muaj kev txav ceev ceev, qhov twg cov theem kho qhov muag txav mus nrog kev nrawm siab los luam theej duab lossis ua cov ntaub ntawv. Cov kev txav no tsim lub zog kinetic uas tuaj yeem tshwm sim ua kev co, tej zaum yuav ua rau cov duab tsis meej lossis ua rau muaj qhov yuam kev hauv kev cim laser. Granite cov khoom siv damping sab hauv ntuj zoo dua li cov hlau alloys. Lub matrix crystalline ntawm lub pob zeb nqus cov kev co siab zaus yuav luag tam sim ntawd, muab qhov chaw "tuag" uas yog qhov tseem ceeb rau kev ua haujlwm kho qhov muag siab.
Tsis tas li ntawd xwb, qhov xwm txheej tsis yog hlau nplaum ntawm granite yog qhov zoo dua rau cov kab ke uas suav nrog cov teeb hluav taws xob rhiab heev lossis cov sensors sib nqus nrog rau lasers. Los ntawm kev tshem tawm kev cuam tshuam electromagnetic los ntawm lub hauv paus nws tus kheej, ZHHIMG muab ib puag ncig inert uas cov hloov pauv tsuas yog cov uas tus neeg sim xav tau.
Kev Koom Tes Thoob Ntiaj Teb rau Kev Tsim Kho Tshiab
Raws li kev lag luam semiconductor thawb mus rau cov nodes me dua thiab lub aerospace sector xav tau cov sensors laser-based ntau dua, qhov xav tau rau cov kev daws teeb meem granite metrology-qib yuav tsuas yog loj hlob. ZHHIMG zoo siab sawv ntawm qhov kev sib tshuam ntawm kev ruaj khov geological thiab optical precision, muab kev txhawb nqa engineering rau OEM cov neeg koom tes thiab cov tsev kawm ntawv tshawb fawb thoob ntiaj teb.
Peb nkag siab tias rau peb cov neeg siv khoom hauv cov lag luam sab hnub poob, "kev lav" ntawm qhov tiaj tus tsis yog tsuas yog ib lo lus lag luam xwb - nws yog qhov tsim nyog ntawm daim ntawv cog lus uas txhawb nqa lawv cov khoom zoo. Los ntawm kev xa khoomcov platform graniteuas ua tau raws li thiab tshaj cov qauv nruj no, peb tab tom pab tsim lub hauv paus rau tiam tom ntej ntawm kev tshawb pom photonic. Kev nrhiav kev ua kom zoo tshaj plaws hauv lub teeb xav tau lub hauv paus ntawm pob zeb.
