Covcollimation tsom lub taub hautuaj yeem muab faib ua lub zog siab thiab nruab nrab qis zog vuam taub hau raws li daim ntawv thov scenario, nrog rau qhov sib txawv tseem ceeb yog cov khoom siv lens thiab txheej. Cov phenomena uas nthuav tawm yog feem ntau kub drift (high-temperature focus drift) thiab lub zog poob. Lub collimating thiab tsom lub taub hau nrog feem ntau zoo kub drift tuaj yeem tswj tau li ntawm 1 hli; Yuav luag tshaj 2 hli; Lub zog poob feem ntau yog hais txog lub zog poob los ntawm lub laser nkag mus rau lub vuam taub hau los ntawm QBH lub taub hau thiab tom qab ntawd tiv thaiv lub lens ntawm hauv qab. Lub zog tseem ceeb yog hloov mus rau hauv lub lens cua sov, uas feem ntau xav tau tsawg dua 3%, qee qhov tuaj yeem ncav cuag 1%, thiab qee qhov tuaj yeem tshaj 5%. Yog li ntawd, ob qho no yog cov cim tseem ceeb rau kev sib koom ua ke thiab tsom mus rau lub taub hau. Nws yog qhov zoo tshaj plaws los ntsuas lawv tus kheej ua ntej siv lossis thov cov chaw tsim khoom los muab cov ntaub ntawv tseem ceeb los xyuas kom meej tias cov khoom ua tau raws li qhov yuav tsum tau muaj ntawm kev tsim khoom ntawm qhov chaw.
Classification ntawm collimated focusing heads – functional classification
Raws li seb nws muaj kev ua haujlwm viav vias thiab seb nws yog ib qho lossis ob daim iav, nws tuaj yeem muab faib ua qhov sib xyaw ua ke thiab tsom lub taub hau, tib lub taub hau pendulum, thiab ob lub pendulum taub hau. Nws tsuas yog tsom rau qhov sib txawv ntawm qhov yuav tsum tau ua, thiab txoj hauv kev ntawm ob lub pendulum yuav ntau dua thiab nyuaj dua li ntawm ib lub pendulum.
Raws li kev sib twlaser system, nws tuaj yeem muab faib ua: (1) dual band composite taub hau (liab xiav, fiber ntau semiconductor, thiab lwm yam), (2) sib xyaw viav vias taub hau (ib lub viav vias), thiab taw tes voj taub hau.
(3)Point nplhaib vuam lub taub hau yog ib yam tshiab ntawm vuam lub taub hau uas tuaj yeem tsim cov kab hluav taws xob muaj zog laser rau hauv cov voj voog lossis taw tes ntiv nplhaib los ntawm cov nqaj shaping, ntsuas lub zog faib. Nws zoo nkaus li zoo li tig lub hwj chim lasers rau hauv lub voj voog lub teeb, tab sis nws txawv. Piv rau cov duab voj voog, lub zog nruab nrab ntawm lub taub hau ntiv nplhaib tsis txaus thiab lawv cov peev xwm nkag tau raug txwv. Txawm li cas los xij, txoj kev yooj yim no ntawm kev ua tiav lub zog hluav taws xob laser zoo ib yam li cov teeb pom kev zoo ib yam los ntawm lub taub hau ntiv nplhaib tuaj yeem ua tiav cov nqi qis thiab qis qis. Nyob rau hauv lub vuam steel, nws muaj qhov tshwj xeeb zoo ntawm cov roj. Vim tias qhov chaw nthuav dav thiab cov khaub ncaws sib txawv ntawm lub zog ntom ntom, tej zaum nws yuav raug rau cov ntaub ntawv cuav (Aluminium).
Collimated focusing lens
Rau cov lo ntsiab muag siv nyob rau hauv laser kis tau tus mob, lawv cov ntaub ntawv yuav muab faib ua ob hom: transmissive cov ntaub ntawv thiab cov ntaub ntawv reflective; Lub collimating focusing lens thiab tiv thaiv lo ntsiab muag yuav tsum yog ua los ntawm cov ntaub ntawv transmissive. Qhov yuav tsum tau muaj: cov khoom siv yuav tsum muaj kev xa mus zoo rau kev ua haujlwm yoj band, kev ua haujlwm siab kub thiab qis thermal expansion coefficient. Feem ntau, lub collimating focusing lens yuav tsum yog ua los ntawm fused silica; Lub lens tiv thaiv yog ua los ntawm cov khoom siv reflective, feem ntau K9 iav. Reflective optical ntsiab yog tsim los ntawm txheej nyias zaj duab xis ntawm high reflectivity hlau khoom ntawm polished iav los yog hlau nto, thiab kev xav tsis muaj dispersion. Yog li ntawd, tsuas yog optical yam ntxwv ntawm reflective optical cov ntaub ntawv yog lawv reflectivity ntawm ntau yam xim ntawm lub teeb. Cov txheej txheem txheej txheem rau cov lo ntsiab muag kho qhov muag yog: 1. ruaj khov ntawm lub teeb; 2. High thermal conductivity; 3. Siab melting point; Nyob rau hauv txoj kev no, txawm tias muaj cov av ntawm cov txheej txheej, kev nqus cua sov ntau dhau yuav tsis ua rau tawg lossis hlawv.
Kev sib xyaw ua ke thiab kev tsom xam feem ntau cuam tshuam rau qhov chaw loj: qhov chaw loj ntawm lub laser beam yog qhov tseem ceeb tsis zoo uas cuam tshuam rau qhov zoo ntawm kev xaim vuam, tshwj xeeb tshaj yog qhov chaw me me tsom rau ntawm qhov chaw ntawm lub workpiece ncaj qha cuam tshuam rau lub zog ceev ntawm lub laser. nqaj. Thaum lub tshuab luam ntawv laser lub zog tas li, qhov chaw me me tuaj yeem ua tiav lub zog siab dua, uas yog qhov zoo rau kev vuam siab melting point thiab nyuaj rau yaj hlau. Nyob rau tib lub sijhawm, nws tuaj yeem tau txais qhov sib piv loj dua thiab ua tau raws li qee qhov tshwj xeeb vuam yuav tsum. Thaum lub melting point ntawm cov khoom siv vuam yog tsawg, los yog thaum muaj qee qhov sib txawv ntawm ob daim hlau thaum lub sij hawm vuam, qhov chaw loj dua feem ntau xaiv kom ua tiav cov txiaj ntsig zoo dua.
Lub collimation focal ntev yog feem ntau ntawm 80-150mm, thiab lub focusing focal ntev yog feem ntau ntawm 100-300mm,; Nws feem ntau yog nyob ntawm qhov kev ncua deb thiab qhov chaw loj (lub zog ceev), nrog rau kev ua siab ntev ntawm qhov chaw mus rau qhov sib txawv ntawm qhov sib txawv (yog tias qhov chaw me dhau, qhov sib txawv yuav xau lub teeb yog tias nws loj dhau, thiab qhov sib txawv. feem ntau tsis ntau tshaj 30% ntawm qhov chaw kab).
