1064nm F-Theta Focusing Lens rau Laser Marking
F-Theta lo ntsiab muag - tseem hu ua scan lub hom phiaj lossis lub hom phiaj tiaj tus - yog lub tshuab lens feem ntau siv hauv kev siv scan.Nyob rau hauv txoj kev nqaj qaum tom qab lub taub hau scan, lawv ua ntau yam haujlwm.
Lub hom phiaj F-theta feem ntau yog siv ua ke nrog galvo-based laser scanner.Nws muaj 2 lub luag haujlwm tseem ceeb: tsom rau qhov chaw laser thiab ua kom cov duab tiaj tus, raws li pom hauv daim duab hauv qab no.Qhov tso zis beam hloov pauv yog sib npaug rau f * θ, yog li tau muab lub npe ntawm f-theta lub hom phiaj.Los ntawm kev qhia txog tus nqi ntawm qhov kev sib txawv ntawm qhov sib txawv hauv lub lens scanning, F-Theta scanning lens yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau lub tiaj tiaj ntawm cov duab dav hlau xws li laser scanning, kos npe, kos duab thiab txiav tshuab.Raws li qhov yuav tsum tau ua ntawm daim ntawv thov, cov diffraction txwv lub lens no tuaj yeem ua kom zoo rau tus account rau wavelength, qhov loj me, thiab qhov ntev focal ntev, thiab distortion tau tuav tsawg dua 0.25% thoob plaws hauv qhov kev pom ntawm lub lens.
