Yuav ua li cas xaiv ib lub tshuab microscope?
(1) Microscopes tuaj yeem muab faib ua monocular, binocular thiab trinocular microscopes raws li tus naj npawb ntawm eyepieces siv. Yog tias cov neeg siv feem ntau muaj cov kev xav tau yooj yim thiab tsuas yog xav tau lub tshuab ntsuas hluav taws xob pheej yig dua, ces xaiv lub tshuab ntsuas monocular. Feem ntau, lub tshuab kuaj kab mob monocular Nws yog qhov tsim nyog rau cov tub ntxhais kawm theem pib, cov tub ntxhais kawm theem nrab, qee lub tsev kho mob me, thiab cov niam txiv yuav khoom rau lawv cov menyuam. Nws siv ntau dua thiab tus nqi pheej yig dua.
(2) Optical part: Lub hauv paus ntawm qhov zoo ntawm lub tshuab tsom iav yog nws qhov chaw kho qhov muag, uas yog, lub qhov muag thiab lub hom phiaj lens. Rau lub hom phiaj lo ntsiab muag, feem ntau nws tuaj yeem muab faib ua ntau theem. Thawj yog lub hom phiaj achromatic lens. Nrog rau lub hom phiaj lens no, tsis yog txhua qhov chaw ntawm daim duab yog qhov tseeb, tsuas yog li 60 feem pua ntawm qhov kev pom pom tseeb, thiab sab nrauv 40 feem pua ntawm cov cheeb tsam yuav muaj qee yam tsis xws luag. Feem ntau peb muab qhov kev soj ntsuam hauv qhov kev pom, yog li nws tsis cuam tshuam rau kev soj ntsuam. Tab sis yog tias koj xav kom tsis muaj qhov tsis xws luag hauv kev pom, koj yuav tsum siv lub hom phiaj achromatic lub hom phiaj lens. Hais txog kev hais lus, tus nqi ntawm lub hom phiaj lens no yuav ntau dua, thiab nws feem ntau yog siv hauv kev kho mob thiab kev tshawb fawb. Kuj tseem muaj qee yam nyob nruab nrab ntawm, uas yog, lub hom phiaj semi-plan achromatic lens. Rau lub tshuab tsom iav siv los ntawm cov tub ntxhais kawm, nws txaus los xaiv thawj ob theem.
(3) Cov khoom siv: Lub neej kev pab cuam ntawm lub tshuab tsom iav ntev heev, qee qhov tuaj yeem ncav cuag ntau tshaj 10 xyoo, yog li cov khoom zoo thiab kev sib dhos nruj dhau los ua qhov lav ntawm nws lub neej kev pabcuam. Yog li ntawd, yuav tsum xaiv lub tshuab tsom iav nrog cov khoom ruaj khov thiab ruaj khov, thiab xaiv cov khoom siv yog alloy los txo qhov deformation. Tsis tas li ntawd, lub lens yuav tsum tau ua los ntawm cov iav kho qhov muag, thiab cov xim txheej txheej yuav tsum du thiab zoo ib yam. Tsis tas li ntawd nco ntsoov tias lub tshuab tsom iav uas koj yuav yog tsim raws li cov qauv dav dav, yog li koj tuaj yeem yooj yim yuav nws thaum koj xav yuav cov khoom siv cuam tshuam yav tom ntej.
(4) Lub teeb qhov chaw: Feem ntau muaj peb hom teeb pom kev zoo rau lub tshuab ntsuas: tungsten filament teeb, fluorescent teeb, thiab halogen teeb. Tungsten filament teeb kuj yog cov teeb ci incandescent. Qhov zoo ntawm hom teeb no yog qhov pheej yig thiab tuaj yeem muab lub teeb ruaj khov. Qhov tsis zoo ntawm kev sim nws yog tias lub teeb tawm yog pom tseeb daj, uas yuav cuam tshuam rau kev soj ntsuam. Tsis tas li ntawd, nws ua kom muaj cua sov ntau dhau, uas yuav cuam tshuam rau qee cov ntaub ntawv thaum pom lub sijhawm ntev. Yog li ntawd, yog tias lub tshuab tsom iav yog lub teeb tungsten, tus nqi kuj pheej yig. Lub teeb fluorescent tuaj yeem muab lub teeb pom kev zoo ib yam li lub hnub ci, thiab ua kom muaj cua sov tsawg heev. Ntxiv mus, cov teeb fluorescent nrog tib lub zog muaj zog dua li cov teeb ci, yog li cov teeb fluorescent yuav txuag hluav taws xob. Ntawm qhov tod tes, nws kim dua. Tus nqi dav dav yog ntau dua 10,000 rau tag nrho tsev neeg, thiab qee qhov yog 20,000 txog 30,000. Cov tuaj txawv teb chaws tseem kim dua. Halogen teeb tuaj yeem muab qhov ci ntsa iab thiab dawb heev. Feem ntau, tus nqi yuav kim dua thaum nruab nrog lub tshuab ntsuas, yog li rau cov tsev kawm qib siab thiab tsev kawm qib siab, nws tsis tas yuav xaiv nws.
