Yuav ua li cas calibrate lub polarizer ntawm ib tug polarizing microscope?
Hauv kev ua haujlwm, cov lus qhia kev vibration ntawm sab sauv thiab sab polarizing lo ntsiab muag ntawm lub tshuab tsom iav polarizing yuav tsum yog orthogonal rau ib leeg, lossis nyob rau sab hnub tuaj-sab hnub poob thiab sab qaum teb-sab qab teb, txhua txoj kab nrog tus ntoo khaub lig filament ntawm lub qhov muag nyob rau hauv kab rov tav thiab ntsug cov lus qhia. Qee lub sij hawm tsuas yog ib qho qis polarizer yog siv rau kev soj ntsuam, kev co kev taw qhia ntawm cov polarizer qis yuav tsum tau txiav txim siab, yog li cov polarizer yuav tsum tau kho thaum lub sijhawm ua haujlwm.
1, eyepiece cross filament nrhiav kom tau
Feem ntau xyuas seb lub eyepiece cross filament yog orthogonal, thiab seb nws puas yog raws li kev vibration kev taw qhia ntawm lub sab sauv thiab sab polarizers, thiab nyob rau tib lub sij hawm, xaiv ib daim ntawm dub mica nrog ib tug ua tiav kev daws teeb meem ncej, txav mus rau hauv nruab nrab ntawm lub eyepiece cross filament, muab qhov kev daws teeb meem slit parallel mus rau ib qho ntawm cov ntoo khaub lig filaments, sau cov naj npawb ntawm cov nplais ntawm lub rooj nqa khoom, thiab tom qab ntawd tig lub rooj tsiaj kom qhov kev daws teeb meem yog sib npaug mus rau lwm qhov ntoo khaub lig filament, thiab tom qab ntawd sau. down tus naj npawb ntawm cov nplais ntawm lub rooj nqa khoom, thiab qhov sib txawv ntawm ob qhov ntsuas yog 90 degree, uas txhais tau hais tias tus ntoo khaub lig filaments yog orthogonal. Qhov sib txawv ntawm ob qhov ntsuas yog 90 degree, qhia tias tus ntoo khaub lig filaments yog orthogonal.
2, Kev txiav txim siab thiab kho qhov kev co kev taw qhia ntawm qis polarizer
Feem ntau, cov mica dub yog siv los xyuas cov kev taw qhia kev co ntawm cov polarizer qis, uas yog vim cov mica dub yog cov pob tshab pob tshab dav dav. Ua ntej tshaj plaws, nrhiav ib qho kev daws teeb meem thiab meej dub mica, txav mus rau hauv nruab nrab ntawm lub qhov muag hla lub filament, tso lub polarizer sab saud, tig lub rooj nqa khoom rau ib lub lim tiam, saib qhov kev hloov ntawm cov xim dub mica, vim tias cov mica dub. kev vibration ntawm kev daws teeb meem ntawm lub teeb nqus * muaj zog, kom cov xim dub mica rau * tob, cov kev taw qhia ntawm kev daws qhov slit yog cov kev taw qhia ntawm kev co ntawm lub polarizer qis.
3, Kho ntawm orthogonality ntawm sab sauv thiab sab polarizers
Tom qab cov kev taw qhia ntawm lub polarizer qis yog kho, tshem tawm cov ntawv thiab thawb nws mus rau hauv lub polarizer sab sauv saib seb lub teb ntawm saib yog tag nrho cov dub los yog nyob rau hauv ib tug extinction xeev. Yog tias nws yog tag nrho cov xim dub, cov lus qhia kev vibration ntawm sab sauv thiab sab polarisers yog orthogonal rau ib leeg. Txwv tsis pub, lub sab sauv polariser yuav tsum tau kho kom qhov chaw saib yog * tsaus. Cov ntsia hlau nres ntawm lub polarizer sab saud yuav tsum tau xoob thaum tig, thiab tom qab ntawd nruj tom qab kho.
