Tej Faults thiab Troubleshooting Methods rau Stereo Microscopes
Tej Faults thiab Troubleshooting Methods rau Stereo Microscopes: Stereo microscopes yog dav siv nyob rau hauv ntau yam sectors ntawm kev lag luam, kev ua liaj ua teb thiab kev tshawb fawb ua tsaug rau lawv ntau yam zoo. Yog tias qee qhov teeb meem tshwm sim thaum siv, lawv tuaj yeem daws nws tus kheej raws li qhov tseeb. Feem ntau ua txhaum raws li kev siv tswv yim muaj xws li: qhov muag tsis pom lossis qias neeg, uas yuav tshwm sim los ntawm cov av ntawm cov qauv, qhov muag qhov muag, lub hom phiaj lens nto los yog theem phaj, thiab tuaj yeem daws tau los ntawm kev ntxuav qhov chaw ntawm qhov hnoos qeev, eyepieces, lub hom phiaj lo ntsiab muag thiab phaj phaj raws li qhov tsim nyog. Cov duab uas tsis yog sib npaug yuav tshwm sim los ntawm kev hloov pauv ntawm qhov kev ncua deb tsis raug, uas tuaj yeem kho tau los ntawm kev kho qhov kev ncua deb ntawm interpupillary; lawv kuj tuaj yeem tshwm sim los ntawm kev hloov kho diopter tsis raug, yuav tsum tau hloov kho diopter, lossis qhov sib txawv ntawm qhov muag sab laug thiab sab xis, yog li cov eyepieces yuav tsum tau kuaj xyuas thiab hloov nrog ib qho ntawm tib qhov kev nthuav dav. Yog tias daim duab tsis meej, lub hom phiaj lens yuav qias neeg thiab yuav tsum tau ntxuav. Yog tias daim duab ua qhov muag plooj thaum lub sijhawm zoom, nws yuav yog vim qhov tsis raug ntawm diopter lossis kev tsom xam, thiab lub diopter thiab kev tsom xam yuav tsum tau hloov kho. Yog tias lub teeb hluav taws kub hnyiab ntau dhau los yog lub teeb flickers tsis zoo, nws yuav tshwm sim los ntawm cov kab hluav taws xob hauv cheeb tsam ntau dhau, lub teeb pom kev tsis zoo los yog xoob xaim txuas; thov ua tib zoo xyuas qhov voltage thiab xyuas kom meej tias tag nrho cov kev sib txuas hluav taws xob ntawm lub tshuab tsom iav muaj kev ruaj ntseg, thiab yog tias tsis yog, hloov lub teeb nrog ib qho tshiab.
Lub calibration ntawm lub stereo microscope ua ntej siv feem ntau muaj xws li ob peb kauj ruam: tsom, pom acuity adjustment, pupillary nrug, thiab hloov qhov muag teev. Hauv qab no yog cov lus piav qhia cais. Kev tsom xam: Muab lub workbench tso rau hauv lub qhov installation ntawm lub hauv paus. Thaum soj ntsuam cov qauv pob tshab, siv lub rooj iav frosted; Thaum soj ntsuam cov qauv opaque, siv lub npov dub thiab dawb. Tom qab ntawd loosen cov fastening screws ntawm lub tsom swb thiab kho qhov siab ntawm daim iav lub cev kom ua tiav qhov kev ua haujlwm nyob deb uas yog roughly raws li qhov loj ntawm lub hom phiaj lens xaiv. Tom qab hloov kho, lub fastening screws yuav tsum tau nruj nreem. Thaum ua kom pom tseeb, nws raug nquahu kom siv cov khoom tiaj tus xws li daim ntawv tiaj tus nrog cov cim luam tawm ntawm nws, cov kav, daim duab peb sab, thiab lwm yam. Kev kho qhov muag pom: Ua ntej, kho cov voj voog pom ntawm sab laug thiab sab xis eyepiece raj mus rau 0 qhov chaw cim. Feem ntau, saib ntawm lub qhov muag sab xis ua ntej. Tig lub zoom handwheel mus rau * tsis tshua muaj magnification txoj hauj lwm, tig lub focusing handwheel thiab lub nrig txog kev pom acuity adjustment nplhaib los kho cov qauv kom txog rau thaum cov duab ntawm cov specimen meej. Tom qab ntawd tig lub log zoom mus rau qhov * siab magnification txoj hauj lwm txuas ntxiv mus kom txog rau thaum cov duab ntawm cov qauv pom tseeb. Nyob rau ntawm no, saib nrog rau sab laug eyepiece raj. Yog tias nws tsis meej, kho lub ntsej muag acuity ntawm sab laug eyepiece raj raws li axis kom txog thaum cov duab ntawm cov qauv pom tseeb.
