Yuav ua li cas xaiv lub microscope zoo rau koj cov kev xav tau
Microscope yog cov cuab yeej kho qhov muag pom tseeb, nws cov thev naus laus zis tseem ceeb yog kho qhov muag thev naus laus zis, cov khoom lag luam zoo, tus yuam sij rau kev saib lub tshuab kho qhov muag (xws li lub teeb pom kev zoo, lub hom phiaj lens, thiab lwm yam), uas yog lub hauv paus ntsiab lus ntawm kev yuav khoom ntawm lub tshuab tsom iav. . Nyob rau hauv cov khoom siv tsom iav txawv teb chaws (Lub teb chaws Yelemees Zeiss, Lub teb chaws Yelemees Leica, Nyiv Nikon, Nyiv Olympus) nyob rau hauv qhov zoo thiab qhov tsis zoo, tus neeg siv yuav tsum muaj kev soj ntsuam zoo nyob rau hauv cov txheej txheem xaiv, tsis txhob mus yuam kev, * thiab tom qab ntawd ua rau kev lag luam poob qis.
Ua ntej, cov duab zoo
Peb siv lub tshuab tsom iav feem ntau yog siv cov qauv kev kho qhov muag kom tau txais cov duab microstructure, thiab tom qab ntawd qhov kev soj ntsuam zoo thiab ntau npaum li cas ntawm cov duab, yog li qhov zoo ntawm cov duab yog * qhov tseem ceeb qhia. Ib daim duab meej nyob rau hauv daim teb ntawm metallography peb hu ua cov duab ntse. Thiab kom tau txais cov duab ntse yuav tsum ua kom tau raws li plaub yam kev mob ntawm qhov sib txawv ntawm qhov sib txawv, qhov ci ci siab, kev tsim cov xim zoo thiab kev daws teeb meem siab. Contrast, brightness, xim luam tawm yog precisely tus neeg siv xaiv yog ib qho yooj yim rau tsis quav ntsej qhov chaw, tsuas yog cov dig muag nrhiav kev daws teeb meem thiab ua rau kev xaiv tsis ua hauj lwm. Piv txwv li, ib qho loj hauv tsev steel zeb yuav nyob rau hauv 2000, ib tug Japanese hom microscope imaging zoo yog deb tshaj li 1985 purchase ntawm German Zeiss microscope, tab sis lub hom phiaj lens ntawm tus lej aperture yog siab dua Zeiss. Qhov tseeb, qhov laj thawj yog qhov yooj yim heev, yog tias cov tuam txhab tsim khoom siv lub tshuab ntsuas ntsuas tsuas yog coj mus rau hauv tus account qhov tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov duab - kev daws teeb meem, thaum tsis quav ntsej lwm yam tseem ceeb xws li qhov sib txawv, ci ntsa iab, xim luam tawm. Lub sijhawm no lub tuam txhab German Zeiss ua kom zoo dua qub, lawv siv ICCS kho qhov muag thiab ** cov cuab yeej tiv thaiv glare los ua cov duab ntawm lub liner, ci ntsa iab, xim luam tawm ntawm cov khoom qub zoo dua qub, kom tau txais * cov ntaub so ntswg maj mam thiab ilv xim. Tsuas yog tom qab ntawd tuaj yeem ua qhov tseeb duab tsom xam.
II. Mechanical stability
Nrog cov duab zoo zoo tsis txaus, tab sis kuj dhau sijhawm los tswj lub xeev zoo. Lub ntsiab lus no peb hu ua 'kev ruaj ntseg tshuab' vim tias lub tshuab tsom iav tsis yog cov khoom siv qis, nws lub neej ua haujlwm ib txwm yuav tsum muaj ntau dua 30 xyoo. Hauv qhov no, nws raug nquahu kom cov neeg siv tsom mus rau cov ntsiab lus hauv qab no: 1, cov khoom siv raw, 2, kev tsim khoom raug, 3, kev tsim kho tshuab, 4, qhov chaw ntawm lub hauv paus chiv keeb (ntau cov chaw tsim khoom siv microscope muaj kev sib koom ua ke hauv lub Hoobkas hauv tsev).
Kev sib piv ntawm cov ntsuas saum toj no nyob rau tib lub sijhawm cov xwm txheej ntawm tus neeg siv yog qhov zoo tshaj plaws los nqa lawv tus kheej cov qauv rau 'kev mus ncig ua si', muaj kev sib piv los txheeb xyuas. Nyob rau hauv luv luv, xaiv ib tug zoo microscope tsis yog tsuas yog mus yuav ib tug high-zoo cov khoom, tab sis kuj yog ib tug deb-seeing peev.
