Ua ntej tshaj, siv qhov kev cais tawm kom khij ntau yam ntawm cov ntsiab lus
Vim tias txhua qhov iav tsom iav muaj qhov sib txawv ntawm qhov ua kom pom tseeb, thiab txoj kev los ntawm kev ua kom pom tseeb yuav yooj yim ua rau ntau hom kev cim, qhov ntawm ntug yog qhov tob tob ntawm qhov focal qhov tob lossis dhau ntawm qhov tob ntawm kev ua kom pom tseeb, uas feem ntau yuav ua teebmeem. Uniformity. Yog li no, tus qauv ntawm kev ua tus cim kos npe yuav tsum xav txog qhov teeb meem ntawm laser lub zog.
Qhov ob, qhov laser cov qhov tso tawm yog thaiv, uas yog, lub teeb laser kis tau los ntawm lub chaw teeb thiab lub lens, thiab qhov chaw tsis muaj.
Lub taub hau laser, cov teeb vaj tse ruaj ruaj thiab tsis muaj teeb meem tsis hloov, uas ua rau qee qhov chaw yuav raug thaiv thaum lub laser kis tau los ntawm lub vibrating lens. Qhov chaw ntawm cov kab zauv yog non-vov tom qab tau npaj los ntawm lub lens field, uas yuav ua rau tsis ntxim li. Tus Kheej.
Muaj kuj yog ib rooj plaub uas tus galvanometer deflecting lens yog puas thiab tsis tau zoo txaus thaum lub teeb laser kis los ntawm qhov chaw ntawm lub lens. Yog li no, lub teeb laser yog inconsistent nrog lub laser zog hauv qhov chaw ntawm lub lens thiab thaj tsam uas tsis yog mob ntawm lub lens, thiab lub laser zog thaum kawg ua rau cov khoom kuj sib txawv, uas ua qhov kos cov nyhuv tsis ncaj.
Qhov peb, qhov tshwm sim thermal lens
Thaum lub laser kis tau los ntawm qhov lens optical (refraction, reflection), nws yuav ua rau lub lens ua kom muaj cua sov thiab tsim ib lub me deformation. Qhov no deformation ua rau lub teeb meem laser nce thiab lub focal ntev ua luv. Yog tias lub tshuab ruaj khov thiab qhov kev ntsuas yog kho kom pom tseeb, tom qab lub laser tig rau ib ntus, laser zog ceev nrooj ua rau cov khoom hloov vim yog thermal lens phenomenon, ua rau tsis sib npaug.
Qeb plaub, theem ntawm lub tshuab tsis hloov, uas yog, laser lens los yog lens field yog tsis mus tib lub rooj ua haujlwm.
Txij li thaum ob tug tsis yog kab rov tav, qhov ntev ntawm lub teeb ntawm lub laser lens los ntawm txoj kev lens thiab ncav lub haujlwm haujlwm yog inconsistent. Lub zog ntawm lub laser poob rau ntawm qhov workpiece yuav muaj ib qho tsis sib xws uas muaj zog, thiab cov nyhuv yuav tsum tau muab tso rau cov khoom. Txhob txwm tsis tau.
5. Vim li cas rau cov khoom siv, xws li cov xim tsis thas xim los yog lub cev thiab tshuaj hauv cov khoom ntawm qhov khoom
Cov ntaub ntawv tseem ceeb heev rau cov hluav taws xob muaj zog ntawm cov hluav taws xob. Feem ntau, nyob rau hauv tib yam khoom, lub zog laser ncav ib qho khoom puas tus nqi yog qhov tseeb. Thaum lub thickness ntawm cov khoom txheej yog sib txawv, los sis lwm cov kev kho mob physicochemical tsis yog tsis txaus, nws yuav tseem ua tsis tau ntawm cov nyhuv tom qab laser npav.
