2.Kev Ruaj Ntsegmkev saib xyuas
Kev saib xyuas kev ruaj ntseg yog ib qho ntawm cov lus qhia tseem ceeb ntawm kev sivcov iav ntau yamCov tsom iav Varifocal tuaj yeem saib xyuas thaj chaw loj thaum tseem tsom mus rau cov ntsiab lus tshwj xeeb. Piv txwv li, hauv cov chaw pej xeem xws li cov khw loj, chaw nres tsheb ciav hlau, thiab tshav dav hlau, lub tsom iav varifocal uas tau teeb tsa siab saum toj no tuaj yeem saib xyuas thaj chaw loj ntawm lub kaum sab xis dav, saib cov neeg ntws thiab qhov xwm txheej tag nrho. Yog tias pom qhov txawv txav, lub tsom iav varifocal tuaj yeem hloov kho sai sai rau qhov chaw telephoto kom zoom rau thaj chaw lossis tus neeg tshwj xeeb, tau txais cov ntaub ntawv ntxaws ntxiv, xws li cov yam ntxwv ntawm lub ntsej muag thiab kev txav mus los, ua rau muaj kev ua haujlwm raws sijhawm.
Cov tsom iav Varifocal kuj tseem siv tau rau kev saib xyuas txoj kev, xws li ntawm qhov chaw sib tshuam thiab txoj kev loj, los saib xyuas kev khiav tsheb, cov xwm txheej ntawm lub tsheb, thiab kev ua txhaum cai. Kev siv lub tsom iav dav dav tso cai rau kev pom panoramic ntawm tag nrho qhov chaw sib tshuam lossis ntu ntawm txoj kev, thaum lub tsom iav telephoto tuaj yeem ntes cov ntsiab lus xws li daim ntawv tsav tsheb thiab kev ua txhaum cai ntawm tus neeg tsav tsheb. Qhov no tso cai rau kev saib xyuas ntau yam haujlwm nrog ib lub koob yees duab, muab cov pov thawj zoo rau kev tswj hwm kev khiav tsheb.
Kev saib xyuas kev ruaj ntseg yog ib qho tseem ceeb ntawm kev siv cov iav varifocal
3.Kev tshawb fawb thiab kev lag luam
Hauv kev tshawb fawb txog kev lag luam thiab kev lag luam,cov iav ntau yamsiv rau hauv cov ntawv thov xws li kev ntsuas qhov tseeb, microscopy, thiab X-ray computed tomography. Piv txwv li, hauv kev sim tshawb fawb, cov iav varifocal tuaj yeem sau cov xwm txheej sim ntawm ntau qhov ntsuas thiab, thaum siv hauv microscopes, tuaj yeem saib cov ntsiab lus ntawm cov khoom me me.
