Thaum Tsov Rog Thoob Ntiaj Teb thib Ob, Zeiss Optical Ua Haujlwm hauv Jena, Lub Tebchaws Yelemees, yog thawj cov chaw tsim khoom los koom nrog cov theem ua tau zoo sib piv optics rau hauv lawv lub microscopes. Qhov cuam tshuam tam sim ntawm kev tshawb fawb txog roj ntsha yog qhov tseem ceeb, thiab kev siv dav dav ntawm cov txheej txheem txuas ntxiv mus rau niaj hnub no.
Thaum twg yog theem sib piv microscopy tsim?
Txoj hauv kev yooj yim tshaj plaws thiab feem ntau tshaj plaws rau cov qauv duab lom neeg yog siv cov theem sib piv, uas yog qhov sib txawv tshwj xeeb-txhim kho cov duab zoo rau cov kab hluav taws xob xaim hluav taws xob tsim los ntawm Frits Zernike (1888-1966) hauv 1932[1] thiab nkag mus rau hauv kev xyaum ua microscopic los ntawm Lub Yim Hli Köhler (1866-1948) thiab Loos hauv 1941 [2, 3].
Leej twg nrhiav pom theem-qhov sib piv lub tshuab ntsuas xyoo 1932?
1900s. 1903: Richard Zsigmondy tsim lub ultramicroscope muaj peev xwm kawm cov khoom hauv qab lub wavelength ntawm lub teeb. Rau qhov no, nws yeej qhov khoom plig Nobel hauv Chemistry hauv xyoo 1925. 1932: Frits Zernike tau tsim lub tshuab ntsuas theem sib piv uas tso cai rau kev kawm txog cov khoom siv tsis muaj xim thiab pob tshab.
Lub tshuab tsom iav zoo li cas tau tsim thaum xyoo 1930 los ntawm Frits Zernike?
Zoo heev Sir. Frits Zernike (Dutch pronunciation: [frɪts ˈzɛrnikə]; 16 Lub Xya Hli 1888 - 10 Lub Peb Hlis 1966) yog Dutch physicist thiab yeej ntawm Nobel nqi zog hauv Physics hauv 1953 rau nws qhov kev tsim ntawm the theem-contrast.
Yuav siv lub tshuab ntsuas dab tsi hauv theem sib piv?
Phase contrast yog qhov zoo tagnrho rau cov qauv thinner, yog li an inverted microscope system tuaj yeem siv tau. Qhov no muab qhov txiaj ntsig ntxiv ntawm kev muaj chaw ua haujlwm ntau dua. Phase contrast kuj tuaj yeem ntsia tau rau ntawm lub tshuab tsom iav ncaj qha.
