Cov lus ceeb toom ntawm kev siv polarizing microscope

Cov lus ceeb toom ntawm kev siv polarizing microscope

Ob lub lim dej polarizing ntawm lub tshuab tsom iav polarizing yog 9 0 degree rau ib leeg kom tau txais qhov hu ua "txoj hauj lwm tsaus", thaum lub sij hawm qhov kev pom yog dub kiag li, yog tias tus qauv yog optically isotropic (ib leeg refractor ), ces tsis muaj teeb meem dab tsi Thaum lub sij hawm tig, lub teb ntawm saib yog tseem tsaus, vim hais tias kev co kev taw qhia ntawm lub linearly polarized lub teeb tsim los ntawm lub polarizer tsis hloov, thiab raws li Marius 'txoj cai, qhov kev siv ntawm lub teeb kis tau tus mob. yog 0. Yog hais tias tus qauv muaj cov yam ntxwv birefringence, lub teb ntawm kev pom yuav ua brighter. Qhov no yog vim hais tias tom qab lub teeb linearly polarized emitted los ntawm lub polarizer nkag mus rau hauv lub cev birefringent, ob hom linearly polarized lub teeb (lub teeb thiab e teeb) nrog txawv vibration lus qhia yog generated. Thaum qhov no Thaum ob hom teeb dhau los ntawm lub ntsuas ntsuas, vim tias e-ray tsis ua raws li txoj cai ntawm refraction, nws cov kev taw qhia polarization nrog lub ntsuas ntsuas tsis yog 90 degree, yog li nws tuaj yeem dhau los ntawm cov ntsuas ntsuas, thiab cov duab ci tuaj yeem ua tau. pom nyob rau hauv qhov kev pom.

Qhov thib ob, lub ntsiab daim ntawv thov ntawm polarizing microscope

1. Biological teb

Hauv cov kab mob uas muaj sia nyob, cov txheej txheem fibrin sib txawv pom cov cim anisotropy, thiab cov ntsiab lus ntawm cov txheej txheem molecular hauv cov fibers tuaj yeem tau txais los ntawm kev siv polarizing microscopy. Xws li collagen, spinning txhob lo lo ntxhuav thaum lub sij hawm faib cell, thiab lwm yam.

2. Kev txheeb xyuas ntawm ntau yam khoom siv roj ntsha thiab tsis muaj roj ntsha

Xws li cov khoom siv hmoov txhuv nplej siab, kev txheeb xyuas cov tshuaj muaj pes tsawg leeg, fiber ntau, kua siv lead ua kua, DNA siv lead ua, thiab lwm yam.

3. Kev tshuaj xyuas kev kho mob

Xws li pob zeb, uric acid crystal detection, mob caj dab, thiab lwm yam.

3. Ceev faj rau kev siv polarizing microscope
