Dab tsi yog qhov sib xyaw optical microscope?
Microscope yog kev sib xyaw ua ke ntawm cov haujlwm sib txawv ntawm lub lens thiab lub tshuab tsom iav lub cev ua ke rau hauv ib hom kev ntsuas, nws tuaj yeem ua rau cov khoom raug soj ntsuam los tsim cov duab loj, thiab yooj yim rau kev soj ntsuam, feem ntau yog siv los soj ntsuam lub qhov muag tsis tuaj yeem pom ncaj qha. cov khoom me me thiab cov khoom microstructure. Feem ntau hais lus, microscopes tuaj yeem muab faib ua optical microscopes thiab electron microscopes nyob ntawm lub teeb ci thiab lub lens system. Optical microscope yooj yim muab tso, nws yog siv lub teeb raws li lub teeb qhov chaw, los ntawm lub optical (iav) lens tsom, yog li ntawd cov khoom los tsim cov duab khoom, thiaj li yuav soj ntsuam, muaj ib tug yooj yim microscopes thiab compound microscopes. Electron microscope yog siv lub wavelength tsis tshua muaj luv luv electron beam raws li lub teeb ci, los ntawm electromagnetic lens tsom, kom cov khoom siv me me, tam sim no feem ntau siv scanning electron microscope thiab penetrating electron microscope.
Lub teeb microscopy (Lub teeb microscopy), feem ntau hu ua LM, raws li qhov nyuaj ntawm cov txheej txheem duab thiab cov qauv ntawm lub tshuab ntsuas qhov muag tuaj yeem muab faib ua ob pawg ntawm cov tshuab microscopes yooj yim thiab nyuaj.
1, Yooj yim microscope
Lub tshuab microscope yooj yim yog tsim los ntawm ib lossis ib pawg ntawm lub lens zoo (plano-convex lossis biconvex lens). Qhov zoo ntawm microscope focal ntev yog luv luv, kev soj ntsuam, lub qhov muag yuav tsum nyob ze rau ntawm lub lens, lub lens yuav tsum nyob ze heev rau cov khoom. Lub tshuab microscope yooj yim uas tsim los ntawm cov duab duab yog yooj yim misshapen thiab distorted, yog li lub zog loj ntawm 20 npaug los yog tsawg dua, kev siv dav dav ntawm cov iav tsom iav uas yog ib hom tshuaj microscope.
2, Compound microscope
Compound microscope yog tsim los ntawm ob lossis ob pawg ntawm cov lo ntsiab muag thiab cov khoom siv lub tshuab microscope mechanical lub cev, feem ntau yog siv hauv chav kuaj rau tib neeg los soj ntsuam cov khoom siv tshuaj lom neeg siv hauv qhov ntsuas, tab sis kuj yog peb lub tswv yim ntawm lub tshuab tsom. Qhov no microscope ob pawg ntawm lo ntsiab muag, ib pab pawg nyob ze rau kev soj ntsuam ntawm cov qauv ntawm lub lens hu ua lub hom phiaj lens los yog hu ua lub hom phiaj lens, lwm pab pawg nyob ze ntawm lub qhov muag, nrog rau kev soj ntsuam ntawm lub lens, paub. raws li eyepiece los yog hu ua eyepiece. Compound microscope vim muaj nuj nqi thiab siv ntau lub hom phiaj, tuaj yeem muab faib ua peb-dimensional (anatomical) microscope thiab dav dav optical microscope.
a, peb-dimensional (anatomical) microscope
Stereo microscope feem ntau yog siv los soj ntsuam cov khoom opaque lossis cov qauv lom neeg ntawm daim ntawv sab nraud, lossis siv hauv cov kab kev lag luam thiab qee cov tshuab biomedical. Qhov no lub tshuab tsom iav vim yog lub teeb ci, qhov tob ntawm qhov chaw thiab lwm yam kev ntsuas, qhov loj me hauv qab 60 npaug, kev daws teeb meem zoo dua.
