Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov rau optical microscopes?
Optical microscope yog ib qho qub thiab cov cuab yeej tshawb fawb, txij li thaum yug los txog tam sim no, muaj peb puas xyoo keeb kwm ntawm optical microscope yog siv ntau yam, xws li hauv biology, chemistry, physics, astronomy thiab lwm yam hauv qee qhov kev tshawb fawb. Kev tshawb fawb kev ua haujlwm yog inseparable ntawm lub microscope.
Tam sim no, yuav luag dhau los ua cov duab ntawm kev tshawb fawb thiab thev naus laus zis, koj tsuas yog yuav tsum tau saib cov ntaub ntawv tshaj tawm txog kev tshawb fawb thiab thev naus laus zis nquag tshwm sim hauv nws daim duab, peb tuaj yeem pom tias cov lus no tsis yog cuav.
Nyob rau hauv biology, lub chaw soj nstuam yog inseparable los ntawm qhov kev sim cov cuab yeej, uas yuav pab tau cov neeg kawm ntawv mus kawm lub ntiaj teb no tsis paub; to taub lub ntiaj teb no.
Lub tsev kho mob yog zui loj daim ntawv thov qhov chaw ntawm lub tshuab tsom, feem ntau yog siv los xyuas cov neeg mob lub cev hloov pauv, kev ntxeem tau ntawm tib neeg cov kab mob, kev hloov pauv ntawm cov ntaub so ntswg ntawm tes thiab lwm yam ntaub ntawv, muab cov kws kho mob nrog kev txhim kho cov kev kho mob rau lub hauv paus siv thiab txhais tau tias. kev txheeb xyuas, hauv genetic engineering, microsurgery, microscope yog tus kws kho mob * cuab yeej; kev ua liaj ua teb, kev yug me nyuam, kev tswj xyuas kab tsuag thiab lwm yam tsis tuaj yeem sib cais los ntawm lub tshuab ntsuas qhov kev pab cuam; industrial ntau lawm Nyob rau hauv kev lag luam ntau lawm, kev ua cov khoom zoo nrhiav kom tau thiab sib dhos hloov kho, kev kawm ntawm cov khoom siv yog lub tshuab tsom iav tuaj yeem qhia lawv cov kev txawj ntse; Cov kws tshawb nrhiav kev ua txhaum cai feem ntau tso siab rau lub tshuab tsom iav los tshuaj xyuas ntau yam ntawm cov kab mob microscopic ntawm kev ua txhaum cai, uas yog ib qho tseem ceeb ntawm kev txiav txim siab cov neeg ua txhaum tiag tiag; Kev Tiv Thaiv Kev Tiv Thaiv Ib Puag Ncig los ntes ntau yam cov pa phem tau los pab microscopes; Geo-mining engineers thiab kab lis kev cai relics thiab archaeologists nrog kev pab los ntawm microscopes pom cov kab ntawm cov pob zeb hauv av tuaj yeem txiav txim siab tob hauv av los yog txiav tawm cov plua plav keeb kwm yav dhau los. Lossis txiav cov plua plav keeb kwm ntawm daim duab tseeb; thiab txawm tias tib neeg lub neej niaj hnub tsis tuaj yeem sib cais los ntawm lub tshuab tsom iav, xws li kev lag luam salon kev zoo nkauj, tuaj yeem siv lub tshuab tsom rau ntawm daim tawv nqaij, plaub hau thiab lwm yam kev sim, thaum koj tuaj yeem tau txais zui cov txiaj ntsig zoo. Pom pom lub tshuab tsom iav thiab tib neeg lub neej tsim khoom nyob ze npaum li cas.
Raws li lub hom phiaj ntawm daim ntawv thov sib txawv, lub tshuab ntsuas hluav taws xob tuaj yeem raug faib ua categorized, ntau hom kab mob lom neeg, lub tshuab kuaj kab mob metallurgical, stereomicroscope, polarized light microscope thiab lwm yam plaub pawg. Raws li lub npe qhia, lub tshuab kuaj kab mob lom neeg feem ntau yog siv rau hauv kev kho mob biomedical, qhov kev soj ntsuam cov khoom feem ntau yog pob tshab lossis translucent microsomes; metallurgical microscope yog tsuas yog siv los saib xyuas qhov chaw ntawm cov khoom opaque, xws li cov qauv metallurgical ntawm cov khoom thiab cov khoom tsis zoo; stereomicroscope nyob rau hauv lub magnification ntawm microscopic khoom imaging nyob rau tib lub sij hawm, tab sis kuj yuav ua rau cov khoom thiab cov duab ntawm tib neeg lub qhov muag nrog kev hwm rau lub orientation ntawm tib yam, thiab muaj kev nkag siab ntawm qhov tob, nyob rau hauv txoj kab nrog rau cov pa pom kev. ntawm tib neeg; polarized microscope siv cov khoom sib txawv los xa cov teeb pom kev zoo rau lub teeb. Polarizing microscope siv cov khoom sib txawv rau polarized lub teeb kis tau tus mob los yog cov yam ntxwv ntawm kev xav kom paub qhov txawv ntawm cov khoom sib txawv. Tsis tas li ntawd, nws tuaj yeem muab faib ua qee yam tshwj xeeb, xws li inverted biomicroscope lossis kab lis kev cai microscope feem ntau yog siv los saib xyuas hauv qab ntawm kab lis kev cai hlab ntsha kab lis kev cai ntawm lub tshuab kuaj kab mob; fluorescence microscope siv qee yam khoom los nqus cov luv luv wavelengths ntawm lub teeb thiab emit ntev wavelengths ntawm lub teeb kom pom qhov muaj nyob ntawm cov tshuaj no, los txiav txim cov ntsiab lus ntawm lawv; Comparative microscopy tuaj yeem nyob rau hauv tib qhov kev pom los tsim ob yam khoom ntawm Comparison microscope tuaj yeem tsim ob yam khoom hauv tib qhov kev pom ntawm cov juxtaposition lossis overlap dluab, txhawm rau sib piv qhov zoo sib xws thiab qhov sib txawv ntawm ob yam khoom.
Cov tshuaj kho qhov muag tsom iav feem ntau yog tsim los ntawm kev kho qhov muag thiab cov qauv siv tshuab los txhawb lawv. Lub tshuab kho qhov muag muaj lub hom phiaj lens, ib lub qhov muag thiab lub ntsej muag condenser, tag nrho cov uas yog qhov nyuaj magnifying lo ntsiab muag ua los ntawm ntau hom iav optical. Lub hom phiaj lens yuav ua kom pom cov duab, nws qhov magnification M khoom los ntawm cov qauv hauv qab no: M object=Δ ∕ f 'object, qhov twg f 'object yog lub focal ntev ntawm lub hom phiaj lens, Δ tuaj yeem txhais raws li qhov kev ncua deb nruab nrab ntawm lub hom phiaj lens thiab eyepiece. Lub eyepiece yuav yog cov duab ntawm lub hom phiaj lens yog magnified dua, rau hauv ib qho kev xav hauv pem hauv ntej ntawm tib neeg lub qhov muag 250mm rau tib neeg kev soj ntsuam, uas yog feem ntau ntawm cov neeg xav zui xis saib txoj hauj lwm, lub eyepiece ntawm magnification ntawm M qhov muag.=250/f' qhov muag, f' qhov muag yog lub qhov muag ntawm qhov ntev focal. Tag nrho cov magnification ntawm lub tshuab microscope yog cov khoom ntawm lub hom phiaj lens thiab eyepiece, piv txwv li, M=M object * M qhov muag=Δ * 250∕f 'qhov muag * f; khoom. Nws tuaj yeem pom tau tias txo cov focal ntev ntawm lub hom phiaj lens thiab lub qhov muag yuav ua rau kom tag nrho cov magnification, uas yog tus yuam sij kom pom cov kab mob thiab lwm yam kab mob nrog lub tshuab tsom, tab sis kuj muaj qhov sib txawv ntawm nws thiab cov iav zoo tib yam.
