Dab tsi yog cov khoom uas ua rau lub tshuab ntsuas qhov muag?
Cov qauv ntawm lub tshuab kho qhov muag tsis tu ncua feem ntau muab faib ua peb ntu: qhov chaw kho qhov muag, qhov muag pom kev, thiab qhov muag pom. Lub luag haujlwm ntawm cov khoom siv kho qhov muag yog los pab kho thiab kho qhov chaw sab nraud, lub luag haujlwm ntawm lub teeb pom kev zoo yog los pab ua duab hauv qab daim iav theem, thiab lub luag haujlwm ntawm qhov kho qhov muag yog saib xyuas thiab siv raws li qhov xav tau.
Cov khoom siv muaj xws li (1) daim iav tuav, (2) daim iav kem, (3) daim iav caj npab, (4) lens chim, (5) lub hom phiaj converter (rotator), (6) iav theem (theem), (7) adjuster .
Lub luag haujlwm ntawm cov khoom siv kho tshuab yog: (1) daim iav tuav: puag, txhawb kev ua haujlwm; (2) Daim iav kem: txuas daim iav puag thiab daim iav caj npab; (3) Daim iav caj npab: ib feem ntawm tes uas tuav lub koob yees duab thaum noj thiab tso; (4) Tube: Sab saum toj kawg ntawm lub raj yog nruab nrog lub qhov muag, thiab qis kawg yog nruab nrog lub hom phiaj lens converter; (5) Lub hom phiaj lens converter (rotator): tuaj yeem pauv cov hom phiaj sib txawv; (6) Daim iav theem (theem): siv los tuav cov iav swb; (7) Adjuster: Txav mus rau theem nce thiab nqis.
Lub teeb pom kev zoo muaj xws li reflectors thiab collectors.
Lub luag haujlwm ntawm lub teeb pom kev zoo yog raws li hauv qab no: (1) Reflecting iav: Nws txoj haujlwm yog los cuam tshuam lub teeb los ntawm lub teeb ci mus rau lub condenser, thiab tom qab ntawd teeb pom cov qauv los ntawm lub teeb lub qhov; (2) Concentrator: Nws txoj haujlwm yog kom pom tseeb lub teeb rau hauv cov qauv kom pom.
Qhov chaw kho qhov muag muaj xws li lub qhov muag thiab lub hom phiaj lens.
Cov haujlwm ntawm qhov kho qhov muag yog raws li hauv qab no: (1) Eyepiece: saib thiab nthuav cov duab khoom, qhov ntev ntawm qhov txo qis nrog qhov nce ntawm qhov loj; (2) Lub Hom Phiaj Lens: Pom cov khoom loj, nws qhov ntev yuav nce nrog qhov nce ntawm qhov loj.
Microscopes tuaj yeem muab faib ua raws li cov qauv hauv microscopic rau hauv polarizing microscopes, optical microscopes, electron microscopes, thiab digital microscopes.
Optical microscopes feem ntau muaj xws li ib feem ntawm qhov muag, qhov pom kev, thiab ib qho khoom siv. Undoubtedly, qhov kho qhov muag yog qhov tseem ceeb tshaj plaws, suav nrog lub ntsej muag thiab lub hom phiaj lens. Raws li thaum ntxov li 1590, Dutch thiab Italian tsom iav manufacturers twb tau tsim cov cuab yeej magnifying zoo ib yam li microscopes. Muaj ntau hom optical microscopes, feem ntau suav nrog lub teeb pom kev zoo (zoo tib yam siv lub tshuab ntsuas qhov muag), tsaus nti microscopes, fluorescence microscopes, theem sib piv microscopes, laser scanning confocal microscopes, polarizing microscopes, sib txawv cuam tshuam microscopy, thiab inverted microscopes.
