Nyob rau lub sijhawm tam sim no ntawm kev tshawb fawb tshawb fawb, qhov twg peb tab tom pom cov qauv ntawm tes ntawm nanometer nplai thiab cov khoom siv ua haujlwm nrog cov pulses kav ntev li plaub npaug ntawm ib thib ob, tus yeeb ncuab ntawm kev vam meej yog pom tsis tau. Nws yog qhov hloov maj mam, qis- zaus ntawm lub tsev, lub suab nrov ntawm lub tshuab cua txias, lossis txawm tias cov tsheb khiav deb ntawm txoj kev nyob ze. Rau cov kws tshaj lij kev ua haujlwm ntawm cov ciam teb no, qhov tseeb ntawm lub sensor tsis cuam tshuam yog tias lub hauv paus kev ua haujlwm nyob rau hauv cov lus tsa suab. Qhov kev muaj tiag no ua rau muaj kev hloov pauv tseem ceeb hauv kev tsim qauv siab -kawg lub chaw soj nstuam, qhov twg granite platform rau confocal microscope systems tsis yog ib qho khoom siv ntxiv lawm, tab sis yog ib qho tseem ceeb ntawm txoj kev kho qhov muag.
Qhov kev sib tw nrog niaj hnub siab - kev daws teeb meem imaging yog tias qhov kev nthuav dav ntxiv, qhov rhiab heev rau ib puag ncig suab nrov nce exponentially. Nyob rau hauv confocal microscopy, qhov twg pinhole apertures yog siv los tshem tawm tawm - ntawm - tsom teeb, txawm tias qhov kev vibration ntawm ob peb puas nanometers tuaj yeem ua rau cov duab tseem ceeb degradation lossis "jitter." Qhov no yog vim li cas granite platform rau confocal microscope yog qhov kev xaiv zoo tshaj plaws rau sab saum toj -cov tsev tshawb fawb qib. Ntuj granite, tshwj xeeb tshaj yog Jinan Dub ntau yam siv los ntawm UNPARALLELED Group, muaj cov qauv mineralogical tshwj xeeb uas muab siab rau sab hauv. Tsis zoo li steel honeycombs lossis txhuas daim hlau, uas tuaj yeem ua tau zoo li lub tswb thiab lub nplhaib ntawm qee zaus, granite absorbs kinetic zog thiab hloov nws mus rau hauv cov kab hluav taws xob, kom ntseeg tau tias cov qauv tseem zoo kawg nkaus rau lub hom phiaj lens.
Thaum peb pivot rau kev lag luam, tshwj xeeb hauv micro-machining, cov ceg txheem ntseeg siab sib npaug. Qhov nce ntawm ultrafast lasers tau hloov kho cov cuab yeej kho mob tsim khoom thiab semiconductor dicing. Txawm li cas los xij, femtosecond laser tsuas yog siv tau yog tias nws cov nqaj taw qhia kev ruaj ntseg yog qhov tseeb. Yog hais tias tus xa khoom optics hloov los ntawm ib feem ntawm micron thaum lub sijhawm pulse, cov txheej txheem "txias ablation" raug cuam tshuam. Siv lub vibration cais granite rau femtosecond laser setups muab qhov tsim nyog loj thiab rigidity rau decouple lub ilv laser qhov chaw los ntawm hauv pem teb cov neeg kho tshuab suab nrov. Because granite has a high density and high modulus of elasticity, it serves as a massive low-pass filter, effectively blocking the high-frequency tremors that can ruin a sub-micron machining task.
Cov kev ua tau zoo tshaj ntawm kev co cais granite rau femtosecond laser daim ntaub ntawv kuj stems los ntawm nws tshwj xeeb thermal inertia. Nyob rau hauv ib lub laser lab, cov cua sov tsim los ntawm lub hwj chim mov los yog lub taub hau laser nws tus kheej tuaj yeem tsim cov thermal gradients hauv zos. Cov rooj zaum hlau nthuav dav thiab cog lus sai, ua rau "beam drift" dhau sijhawm. Granite, nrog nws cov coefficient tsawg ntawm thermal expansion thiab siab thermal mass, reacts qeeb qeeb rau qhov kub thiab txias. Qhov kev ruaj ntseg no ua kom ntseeg tau tias thaum lub laser ua raws li thaum sawv ntxov, nws nyob twj ywm nyob rau hauv tag nrho cov kev hloov pauv ntau lawm, ua kom pom tseeb thiab txo qhov xav tau ntawm nruab nrab - txheej txheem recalibration.
Ntawm UNPARALLELED Group, peb lub tswv yim engineering yog hauv paus hauv kev ntseeg tias cov khoom yog cov lus. Thaum peb tsim cov granite platform rau confocal microscope, peb tsis tsuas yog shaping pob zeb; peb yog engineering ib puag ncig ruaj khov rau kev tshawb pom. Peb cov pob zeb tau dhau los ua cov txheej txheem kev xaiv nruj kom ntseeg tau tias qhov tsis muaj qhov cuam tshuam sab hauv lossis suav nrog uas tuaj yeem cuam tshuam cov qauv kev ncaj ncees. Txhua qhov chaw yog tom qab ntawd ua tib zoo txhais tes-lapped kom ua tiav qhov kev sib haum xeeb uas siab tshaj cov qauv ntsuas thoob ntiaj teb. Qhov theem ntawm qhov zoo tshaj plaws ntawm qhov chaw no yog qhov tseem ceeb vim tias nws tso cai rau kev sib xyaw ua ke ntawm huab cua - cov theem kev coj tus kheej, uas yuav tsum tau nyob ze -pav zoo meej siv rau kev khiav lag luam yam tsis muaj kev sib txhuam- vim muaj kev vibration.
Tsis tas li ntawd, lub neej ntev ntawm ntuj granite yog ib qho tseem ceeb rau cov neeg saib xyuas hauv Tebchaws Europe thiab North America. Nyob rau hauv lub ntiaj teb ntawm kev npaj obsolescence, siab -zoogranite puagyog ib lub cuab tam ruaj khov. Nws tsis xeb, nws tsis corrode nyob rau hauv lub xub ntiag ntawm cov tshuaj nyob rau hauv lub chaw soj nstuam, thiab nws tsis poob nws cov duab vim kev nyuaj siab nyob rau hauv lub sij hawm. Txawm hais tias nws txhawb nqa lub siab -throughput screening system los yog ua raws li lub vibration cais granite rau femtosecond laser kev tshawb fawb, cov khoom tseem geologically ruaj khov rau xyoo lawm. Qhov kev ruaj khov no muab qhov "Golden Reference" uas ntseeg tau rau ntev - cov kev tshawb fawb ntev ntev uas cov ntaub ntawv sib xws yuav tsum muaj ntau xyoo.
Raws li peb saib mus rau yav tom ntej ntawm photonics thiab biophysics, kev koom ua ke ntawm kev txawj ntse txawj ntse thiab kev tshawb pom tsis siv neeg tsuas yog nce qhov kev thov rau lub cev ruaj khov. AI algorithms rau kev tsim kho duab tuaj yeem them nyiaj rau qee lub suab nrov, tab sis lawv tsis tuaj yeem hloov lub teeb liab ntshiab, ruaj khov. Los ntawm kev muab lub platform granite rau confocal microscope uas tshem tawm cov suab nrov ntawm qhov chaw, UNPARALLELED Group ua rau cov kws tshawb fawb los ntes cov ntaub ntawv ncaj ncees siab tshaj plaws. Qhov "cov ntaub ntawv huv" txoj hauv kev no yog qhov kawg ua rau muaj kev cuam tshuam hauv kev tshawb nrhiav tshuaj thiab cov ntaub ntawv tshawb fawb.
Hauv kev xaus, lub hauv paus ntawm koj cov cuab yeej precision yuav tsum tsis txhob xav tom qab. Nyob rau hauv qhov sib npaug sib npaug ntawm lub teeb thiab teeb meem, kev ruaj ntseg ntawm theem tseem ceeb npaum li lub zog ntawm lub laser. UNPARALLELED Group tseem ua tus coj txoj hauv kev los muab cov hauv paus tseem ceeb no, ua kom ntseeg tau tias lub ntiaj teb cov khoom siv hluav taws xob zoo tshaj plaws thiab femtosecond lasers muaj qhov ntsiag to, ruaj khov kev txhawb nqa lawv yuav tsum tau kho dua cov kev txwv ntawm qhov ua tau. Los ntawm kev xaiv ntuj granite, koj xaiv cov khoom uas tau ruaj khov rau ntau lab xyoo, tsim los ua kom koj cov kev tshawb fawb ruaj khov rau xyoo tom ntej.
