Calibration Methods rau Biological Microscopes
Cov txheej txheem calibration ntawm bio microscope yuav tsum suav nrog plaub yam nram qab no.
1. Kev tshwm sim
Cov duab ntawm lub optical system nyob rau hauv tag nrho cov teb ntawm saib yuav tsum tau meej, thiab yuav tsum tsis txhob muaj ntxoov ntxoo los yog reflected lub teeb me ntsis uas cuam tshuam rau kev soj ntsuam nyob rau hauv lub teb ntawm saib. Qhov chaw ntshiab ntawm kev yees duab yuav tsum yog concentric nrog thaj tsam ntawm kev pom. Kev txav ntawm txhua qhov yuav tsum tau hloov pauv thiab ruaj khov, tsis muaj qhov nplaum thiab dhia, thiab qhov pom ntawm qhov pom yuav tsum zoo ib yam.
2. Kev kho kom zoo ntawm cov ntawv sau lub log ntawm tes
Qhov zoo-tuning handwheel yuav tsum hloov tau yooj yim thiab ruaj khov, nrog me ntsis nruj. Rau qhov zoo-tuning lub ncua sij hawm ntawm cov kab cim ntawm lub handwheel, ntsuas qhov pib, nruab nrab thiab qhov kawg ntawm lub handwheel. Ua ntej kev ntsuas, kho qhov taw qhia ntawm lub tshuab kuaj kab mob lom neeg nrog lub teeb pom kev tshwj xeeb kom paub tseeb tias qhov ntsuas thiab lub tshuab ntsuas ntsuas tau nrawm thiab ruaj khov. Thaum kho qhov taw qhia, xyuas kom meej tias lub taub hau ntsuas yog nyob rau hauv ntsug sib cuag nrog rau theem. Kho lub ntsej muag tsom iav ntawm lub tshuab kuaj kab mob lom neeg kom xoom qhov kev nyeem ntawv ntawm qhov ntsuas. Tig lub tsheb kauj vab tsom 10 teev, nyeem tus nqi qhia, thiab siv 1/10 ntawm tus nqi qhia raws li qhov ntsuas tau. Qhov nruab nrab tus nqi ntawm qhov ntsuas ntawm qhov pib, nruab nrab thiab kawg txoj haujlwm yog siv los ua cov txiaj ntsig calibration.
3. Lub hom phiaj lens magnification yuam kev hloov
Kho qhov teeb pom kev zoo mus rau qhov chaw tsim nyog, teeb tsa lub qhov muag nrog lub ntsuas qhov ntsuas ntawm ib lub tes tsho ntawm lub tshuab kuaj kab mob lom, tso cov qauv iav ntsuas rau ntawm theem, thiab kho qhov muag thiab tus qauv iav kav kom cov kab reticle sib phim. tus qauv. Cov kab kab ntawm cov iav kav yog sib npaug kom tsis txhob ntsuas qhov yuam kev. Kho cov theem kom lub xoom txoj hauj lwm ntawm lub iav kav yog raws li ib tug kawg ntawm lub reticle, thiab ces nyeem ncaj qha.
4. Kev hloov kho ntawm reticle lub sij hawm yuam kev ntawm eyepiece kav
Tom qab calibrating lub magnification yuam kev ntawm lub hom phiaj ntawm lub tshuab microscope, qhov project no yuav ua tau yam tsis muaj metrological calibration. Cov txheej txheem calibration tshwj xeeb yog muab cov qauv iav nplai nrog qhov sib faib tus nqi ntawm 0.01mm rau ntawm theem, nruab 10x microscope eyepiece, thiab ua kom pom tseeb kom txog thaum lub qhov muag pom qhov pom tseeb. Kho lub tshuab tsom iav qhov muag thiab cov qauv iav ntsuas kom haum cov kab kawg ntawm ob, thiab xyuas kom meej tias cov kab thiab nplai ntawm ob qho tib si yog tib yam.
