Cov hauv paus ntsiab lus kho qhov muag thiab cov khoom siv rau lub teeb microscopesOptical cov ntsiab lus thiab cov khoom siv rau lub teeb microscopes
Txoj Cai ntawm Optics
Microscope yog siv lub ntsiab lus ntawm convex lens magnification imaging txoj cai, tib neeg lub qhov muag tsis tuaj yeem paub qhov txawv ntawm cov khoom me me uas loj rau qhov loj ntawm tib neeg lub qhov muag tuaj yeem paub qhov txawv, qhov tseem ceeb tshaj plaws yog ua kom cov khoom me me nyob ze rau ntawm lub qhov muag (lub kaum sab xis ntawm qhov pom ntawm cov khoom loj nyob rau hauv daim duab retina yog loj), nrog rau lub angular magnification ntawm M hais tias lub magnification ntawm lub peev xwm ntawm lawv. Vim tias tib yam khoom rau lub qhov muag lub kaum sab xis thiab qhov kev ncua deb ntawm cov khoom los ntawm lub qhov muag, yog li cov kev cai dav dav ntawm cov duab ntawm qhov deb ntawm lub qhov muag rau 25 cm (visual nrug) ntawm qhov kev nthuav dav ntawm cov cuab yeej rau qhov magnification. Lub kaum sab xis ntawm kev pom ntawm ib qho khoom pom los ntawm lub tshuab tsom iav feem ntau yog me me, yog li qhov piv ntawm lub kaum sab xis ntawm qhov pom tuaj yeem hloov tau los ntawm qhov piv ntawm nws tangent.
Lub tshuab tsom iav muaj ob lub lens sib txuas, thiab txoj kev kho qhov muag tau pom hauv daim duab. Object AB los ntawm lub hom phiaj lens mus rau hauv ib tug magnified inverted khoom duab A1B1, A1B1 nyob rau hauv lub eyepiece ntawm lub focal ntev ntawm cov khoom ntawm sab hauv, los ntawm lub eyepiece mus rau hauv ib tug magnified virtual duab ntawm A2B2 nyob rau hauv qhov kev ncua deb ntawm lub ci pom kev zoo.
Khoom siv
Nrog rau txoj kev loj hlob ntawm niaj hnub biotechnology thiab kev txhim kho ntawm tib neeg cov kev xav tau ntawm microscopes, ib qho kev kho qhov muag micro-imaging system tau nyob deb ntawm tsis muaj peev xwm ua tau raws li cov cai ntawm tib neeg lub micro-photoography. Qhov kev taw qhia ntawm lub tshuab ntsuas hluav taws xob digital cim qhov kev nkag ntawm optical microscope rau hauv lub sijhawm tshiab digital. Digital microscope tsis tsuas yog sib txuas cov duab zoo ntawm lub tshuab ntsuas qhov muag, tab sis kuj ua ke nrog cov tshuab photoelectric hloov dua siab tshiab thiab kua siv lead ua kua tshuaj ntsuam thev naus laus zis, kom lub tshuab tsom iav muaj peev xwm los soj ntsuam microscopically, thiab tib lub sijhawm, nws paub txog cov khoom siv digital. thiab xa cov duab microscopic.
Txawm li cas los xij, tus nqi siab ntawm digital microscope tsis ua rau nws siv dav, ib yam tshiab ntawm cov khoom siv microscopic digital - microscopic digital koob yees duab kuj tau los ua. Raws li lub koob yees duab digital microscope tshwj xeeb, lub koob yees duab digital microscope tuaj yeem txuas tau yooj yim rau txhua lub tshuab tsom kom ua tiav kev hloov pauv ntawm optical microscope rau digital microscope.
Raws li cov khoom siv tsim nyog rau kev siv lub tshuab kho qhov muag, lub koob yees duab micro-digital kuj tau muab faib ua ntau qib sib txawv raws li cov kev xav tau sib txawv, qee qhov tsim nyog rau kev xav tau siab dua ntawm cov duab, thiab qee qhov tsim nyog rau cov kev xav tau dav dav. Raws li lub koob yees duab microscope yooj yim thiab ceev ceev, lub koob yees duab microscope digital yuav siv tau zoo heev.
Optical microscope accessories yog eyepiece lub hom phiaj lens thiab lub teeb qhov chaw, thiab lwm yam. Tau kawg, nrog rau txoj kev loj hlob ntawm science thiab technology, optical microscope maj mam txawm nruab nrog ib lub koob yees duab system, thiaj li hais tias nws yuav tsum tau tso tawm nyob rau hauv lub saib, saib lub sij hawm kuj yooj yim dua. .
Tsis tas li ntawd, lub teeb pom kev zoo ntawm lub teeb pom kev zoo kuj tseem ceeb dua, nruab nrog lub nplhaib lub teeb ci thaum tseem muaj lub teeb ci, clip hom teeb qhov chaw. Optical microscope puag tsis zoo ib yam, qee qhov yog ua los ntawm yas, qee qhov yog alloy, qhov zoo dua yog cov khoom siv alloy, alloy tsis yooj yim rau deform. Qhov kev nthuav dav kuj tsis zoo ib yam, qee qhov tuaj yeem txuas ntxiv ob npaug, qee qhov tsuas yog qhov sib npaug, lossis ob zaug.
