Hom teeb pom kev zoo siv nyob rau hauv optical microscopes thiab dab tsi yog cov yam ntxwv ntawm txhua tus?
[Electron microscope
Electron microscope raws li tus qauv thiab kev siv yuav muab faib ua kis tau tus mob electron microscope, scanning electron microscope, reflection electron microscope thiab emission electron microscope. Kev xa hluav taws xob tshuab hluav taws xob feem ntau yog siv los soj ntsuam cov neeg uas muaj lub tshuab microscopes tsis tuaj yeem paub qhov txawv ntawm cov qauv zoo ntawm cov khoom; scanning electron microscope yog tsuas yog siv los soj ntsuam cov morphology ntawm cov khoom siv, tab sis kuj nrog X-ray diffractometer los yog electron spectrometer ua ke los tsim cov electron microprobe, siv rau kev tsom xam ntawm cov khoom muaj pes tsawg leeg; emission electron microscope rau kev kawm ntawm qhov chaw ntawm tus kheej-emission ntawm electrons.
[Optical Microscope
Optical microscope muaj ntau hom kev faib tawm: Chi-Tay tuaj yeem muab faib ua trinocular, binocular thiab monocular microscope raws li tus naj npawb ntawm eyepieces siv; Raws li seb daim duab puas muaj kev nkag siab ntawm peb-dimensional tuaj yeem muab faib ua stereoscopic tsis pom kev thiab tsis yog stereoscopic pom lub microscope; raws li kev soj ntsuam ntawm daim duab tuaj yeem muab faib ua cov khoom siv roj ntsha thiab cov hlau nplaum, thiab lwm yam .; raws li lub hauv paus ntsiab lus ntawm optics tuaj yeem muab faib ua polarised, theem sib piv thiab qhov sib txawv cuam tshuam qhov sib piv ntawm microscopy, thiab lwm yam.; Raws li hom teeb pom kev zoo tuaj yeem muab faib ua lub teeb zoo tib yam, fluorescence, lub teeb infrared thiab laser Microscope, thiab lwm yam; Raws li hom receiver tuaj yeem muab faib ua qhov pom, duab thiab TV microscopes. Feem ntau siv cov tshuab tsom xam muaj xws li binocular nruam zoom stereomicroscope, metallurgical microscope, polarizing microscope, ultraviolet fluorescence microscope, thiab lwm yam.
Lub tshuab tso suab tso suab binocular siv ob txoj hauv kev kho qhov muag los muab cov duab stereoscopic rau sab laug thiab sab xis. Nws yog ib qho tseem ceeb ntawm ob lub raj microscopes muab tso rau ntawm ib sab, lub qhov muag axis ntawm ob lub raj yog qhov sib npaug ntawm cov neeg uas muaj kev soj ntsuam binocular ntawm ib qho khoom tsim los ntawm lub kaum sab xis ntawm kev pom, thiaj li tsim tau ib daim duab stereoscopic pom ntawm peb sab. qhov chaw. Binocular stereomicroscope yog dav siv nyob rau hauv biological thiab kev kho mob teb rau seem lag luam thiab microsurgery; hauv kev lag luam, nws yog siv rau kev soj ntsuam, sib dhos thiab tshuaj xyuas cov khoom me me thiab kev sib xyaw ua ke.
Metallographic microscope tshwj xeeb yog siv los saib xyuas lub koom haum metallographic ntawm cov khoom opaque xws li hlau thiab cov ntxhia. Cov khoom opaque no tsis tuaj yeem pom nyob rau hauv lub teeb pom kev zoo tib yam, yog li qhov sib txawv ntawm metallographic thiab dog dig microscopes yog tias yav dhau los rau lub teeb pom kev, thaum yav tas los kis lub teeb pom kev zoo. Hauv metallographic microscopy, lub teeb pom kev zoo yog coj los ntawm kev coj ntawm lub hom phiaj lens mus rau saum npoo ntawm cov khoom raug soj ntsuam, thiab pom los ntawm cov khoom nto thiab rov qab mus rau lub hom phiaj lens rau kev yees duab. Hom kev cuam tshuam illumination no kuj tau siv dav hauv kev tshuaj xyuas ntawm kev sib xyaw ua ke wafers.
Ultraviolet fluorescence microscope yog lub tshuab tsom iav uas siv lub teeb ultraviolet los txhawb cov fluorescence rau kev soj ntsuam. Qee cov qauv tsis tuaj yeem pom hauv lub teeb pom kev, tab sis tom qab staining, lawv tuaj yeem tawm lub teeb pom kev vim fluorescence thaum irradiated nrog ultraviolet lub teeb, tsim cov duab pom. Cov microscopes no feem ntau siv hauv biology thiab tshuaj.
Television microscopes thiab charge-coupled microscopes yog microscopes uas siv lub koob yees duab TV lub hom phiaj lossis cov khoom sib txuas them nqi raws li cov khoom tau txais. Nyob rau hauv cov duab tiag tiag saum npoo ntawm lub tshuab tsom mus rau hauv lub hom phiaj lub koob yees duab TV lossis them tus nqi sib txuas es tsis txhob ntawm tib neeg lub qhov muag ua tus txais, los ntawm cov khoom siv optoelectronic los hloov cov duab kho qhov muag mus rau hauv cov duab hluav taws xob, thiab tom qab ntawd qhov loj ntawm kev kuaj pom, particle suav. thiab lwm yam haujlwm. Hom tshuab ntsuas no tuaj yeem siv ua ke nrog lub khoos phis tawj, uas pab txhawb kev automation ntawm kev tshawb pom thiab kev ua cov ntaub ntawv, feem ntau siv rau hauv qhov xav tau los ua haujlwm ntau lub sijhawm ua haujlwm nyuaj.
Scanning microscope yog lub teeb pom kev zoo tuaj yeem txheeb ze rau qhov khoom nto rau kev tshuaj ntsuam xyuas ntawm lub tshuab tsom. Nyob rau hauv lub scanning microscope cia siab rau qhov nqaim ntawm lub teb kom paub meej tias lub hom phiaj lens kom ua tiav qhov kev daws teeb meem siab tshaj plaws, thaum siv optical lossis mechanical scanning txoj kev, kom cov duab teeb pom kev txheeb ze rau cov khoom nto hauv thaj chaw loj ntawm kev pom rau kev tshuaj ntsuam, thiab cov ntaub ntawv txheej txheem thev naus laus zis kom tau txais cov duab hluavtaws ntawm thaj chaw loj ntawm cov ntaub ntawv. Hom microscope no haum rau kev soj ntsuam ntawm thaj chaw loj ntawm cov duab saib uas xav tau kev daws teeb meem siab. Coarse focusing helix: wide range of up and down mobilization of the lens chim.
