Yuav ua li cas paub qhov zoo ntawm lub lens pawg siv nyob rau hauv lub microscope
Lub hollow hlau lub tog raj kheej nrog ob peb axes ntawm lub microscope ntawm tib txoj kab ncaj nraim (piv txwv li, qhov kho qhov muag axis), los yog hlau diaphragm teem nyob rau hauv parallel nrog ib ncig lub voj nyob rau hauv nruab nrab ntawm lub Olympus microscope yog ib tug electrode nrog ib tug axisymmetric qauv. Thaum muaj qee qhov hluav taws xob siv rau lawv, axisymmetrically faib electrostatic teb tuaj yeem tsim tawm. Qhov hluav taws xob fluttering no tuaj yeem ua rau lub tshuab ntsuas hluav taws xob ua kom pom tseeb, yog li nws hu ua electrostatic microscope. Muaj ntau ntau hom electrostatic lo ntsiab muag. Yog tias nws yog tus cwj pwm los ntawm qhov muaj peev xwm faib tawm ntawm axis ntawm symmetry tom qab siv qhov hluav taws xob, Olympus tuaj yeem kwv yees faib cov tshuab ntsuas ntsuas rau plaub pawg:
Lub peev xwm ntawm qhov chaw ntawm sab laug thiab sab xis ntawm ib leeg-muaj peev xwm lens-microscope yog qhov tsis tu ncua thiab sib npaug ntawm tus nqi: lub peev xwm ntawm axis ntawm sab laug thiab sab xis ntawm lub lens immersion-microscope yog tas li tab sis tsis sib npaug ntawm tus nqi. ) Cov nyhuv ntawm lub lens yog concentrated nyob ze ntawm lub voj voog ntawm lub diaphragm. Lub zog hluav taws xob muaj zog ntawm ob lub axes ntawm lub tshuab tsom iav yog txhua qhov tas mus li. Aperture diaphragms ib leeg yog siv me ntsis, tab sis feem ntau lawv tuaj yeem siv los ua ib feem tseem ceeb ntawm qee cov lo ntsiab muag nyuaj:
Lub hom phiaj immersion-cov khoom siv hluav taws xob tso tawm ncaj qha rau hauv lub tshuab hluav taws xob ntawm hom kab no, thiab qhov muaj peev xwm ntawm axis ntawm sab nraud ntawm Nikon lens (piv txwv li, sab duab) yog tas li. Ntxiv rau qeb plaub, lwm yam peb hom ntawm lub hwj chim qhib lo ntsiab muag tuaj yeem suav tias yog lub tshuab tsom, thiab yog li lawv cov khoom-sab focal ntev thiab cov duab-sab focal ntev tuaj yeem txiav tawm. Cov qauv focal ntev ntawm thawj thiab thib ob hom lo ntsiab muag yog:
Nws tsis yog qhov nyuaj los qhia tias qhov ntev ntawm lub focal ntev nyob rau hauv lub unipotential lo ntsiab muag thiab immersion lo ntsiab muag yog ib txwm zoo, uas txhais tau hais tias cov Nikon microscopes yeej ib txwm converging. Ib qho aperture lo ntsiab muag tuaj yeem tsim lub lens sib txawv, thiab kev ua haujlwm ntawm lub hom phiaj immersion lens yuav tsum tau soj ntsuam raws li cov xwm txheej tshwj xeeb. Ib qho piv txwv ntawm lub nruas yog cov phom hluav taws xob siv hauv Nikon microscopes thiab lwm cov kab hluav taws xob hluav taws xob. Nws txoj haujlwm yog tsim cov kab hluav taws xob hluav taws xob nrog qee qhov sib txawv ntawm cov duab thiab qhov siv tam sim no.
